Therefore, it would be ideally suited to obtain good statistical sampling of fast-moving tissues using spectral-based techniques to derive the backscatter coefficient (BSC) and associated quantitative parameters. In UI, an image is formed by insonifying the medium with plane waves steered at different angles, beamforming them and compounding the resulting radiofrequency images. We aimed at validating, experimentally, the effect of these beamforming protocols on the BSC, under both isotropic and anisotropic conditions. Using UI techniques with a linear array transducer (5–14 MHz), we estimated the BSCs of tissue-mimicking phantoms and flowing porcine blood at depths up to 35 mm with a frame rate reaching 514 Hz. UI-based data were compared with those obtained using single-element transducers and conventional focusing imaging. Results revealed that UI compounded images can produce valid estimates of BSCs and effective scatterer size (errors less than 2.2 ± 0.8 and 0.26 ± 0.2 dB for blood and phantom experiments, respectively). This work also describes the use of pre-compounded UI images (i.e., steered images) to assess the angular dependency of circulating red blood cells. We have concluded that UI data sets can be used for BSC spectral tissue analysis and anisotropy characterization.", "publicationTitle": "Ultrasound in Medicine & Biology", "publisher": "", "place": "", "date": "septembre 2015", "volume": "41", "issue": "9", "section": "", "partNumber": "", "partTitle": "", "pages": "2506-2519", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Ultrasound in Medicine & Biology", "DOI": "10.1016/j.ultrasmedbio.2015.04.017", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0301562915003166", "accessDate": "2016-01-05T15:01:12Z", "PMID": "", "PMCID": "", "ISSN": "0301-5629", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "ScienceDirect", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Backscatter coefficient", "type": 1 }, { "tag": "Erythrocyte aggregation", "type": 1 }, { "tag": "Planar reflector technique", "type": 1 }, { "tag": "Quantitative ultrasound", "type": 1 }, { "tag": "Reference phantom technique", "type": 1 }, { "tag": "Spectral analysis", "type": 1 }, { "tag": "plane wave imaging", "type": 1 } ], "collections": [], "relations": {}, "dateAdded": "2016-01-05T15:01:12Z", "dateModified": "2016-01-05T15:01:12Z" } }, { "key": "NUWFR9V6", "version": 8, "library": { "type": "group", "id": 454820, "name": "Groupe 8 Yang, Takka, El Mamouni, Delimi", "links": { "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/454820/items/NUWFR9V6", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi/items/NUWFR9V6", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/454820/items/AGBVTXRC", "type": "application/json" } }, "meta": { "createdByUser": { "id": 2842212, "username": "divena23", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/divena23", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "NUWFR9V6", "version": 8, "parentItem": "AGBVTXRC", "itemType": "attachment", "linkMode": "imported_file", "title": "1-s2.0-S1936878X14004410-main.pdf", "accessDate": "", "url": "", "note": "", "contentType": "application/pdf", "charset": "", "filename": "1-s2.0-S1936878X14004410-main.pdf", "md5": "7e5e785c36f586f12f2af8848888ec0a", "mtime": 1452004623662, "tags": [], "relations": {}, "dateAdded": "2016-01-05T14:58:36Z", "dateModified": "2016-01-05T14:58:36Z" } }, { "key": "MSCN2DBP", "version": 5, "library": { "type": "group", "id": 454820, "name": "Groupe 8 Yang, Takka, El Mamouni, Delimi", "links": { "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/454820/items/MSCN2DBP", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi/items/MSCN2DBP", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/454820/items/AGBVTXRC", "type": "application/json" } }, "meta": { "createdByUser": { "id": 2842212, "username": "divena23", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/divena23", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "MSCN2DBP", "version": 5, "parentItem": "AGBVTXRC", "itemType": "note", "note": "Article de la revue ScienceDirect.

Although optical microscopy is still limited to surface imaging owing to optical wave diffusion and fast decorrelation in tissue, revolutionary approaches such as fluorescence photo-activated localization microscopy led to a striking increase in resolution by more than an order of magnitude in the last decade. In contrast with optics, ultrasonic waves propagate deep into organs without losing their coherence and are much less affected by in vivo decorrelation processes. However, their resolution is impeded by the fundamental limits of diffraction, which impose a long-standing trade-off between resolution and penetration. This limits clinical and preclinical ultrasound imaging to a sub-millimetre scale. Here we demonstrate in vivo that ultrasound imaging at ultrafast frame rates (more than 500 frames per second) provides an analogue to optical localization microscopy by capturing the transient signal decorrelation of contrast agents--inert gas microbubbles. Ultrafast ultrasound localization microscopy allowed both non-invasive sub-wavelength structural imaging and haemodynamic quantification of rodent cerebral microvessels (less than ten micrometres in diameter) more than ten millimetres below the tissue surface, leading to transcranial whole-brain imaging within short acquisition times (tens of seconds). After intravenous injection, single echoes from individual microbubbles were detected through ultrafast imaging. Their localization, not limited by diffraction, was accumulated over 75,000 images, yielding 1,000,000 events per coronal plane and statistically independent pixels of ten micrometres in size. Precise temporal tracking of microbubble positions allowed us to extract accurately in-plane velocities of the blood flow with a large dynamic range (from one millimetre per second to several centimetres per second). These results pave the way for deep non-invasive microscopy in animals and humans using ultrasound. We anticipate that ultrafast ultrasound localization microscopy may become an invaluable tool for the fundamental understanding and diagnostics of various disease processes that modify the microvascular blood flow, such as cancer, stroke and arteriosclerosis.", "publicationTitle": "Nature", "publisher": "", "place": "", "date": "Nov 26, 2015", "volume": "527", "issue": "7579",

The majority of CAD-induced deaths are due to the rupture of vulnerable plaques. Accurate assessment of plaques is crucial to optimize treatment and prevent death in patients with CAD. Current diagnostic techniques are often limited by either spatial resolution or penetration depth. Several studies have proved that the combined use of optical and ultrasonic imaging techniques increase diagnostic accuracy of vulnerable plaques. Here, we introduce an ultrafast optical-ultrasonic dual-modality imaging system and flexible miniaturized catheter, which enables the translation of this technology into clinical practice. This system can perform simultaneous optical coherence tomography (OCT)-intravascular ultrasound (IVUS) imaging at 72 frames per second safely in vivo, i.e., visualizing a 72 mm-long artery in 4 seconds. Results obtained in atherosclerotic rabbits in vivo and human coronary artery segments show that this ultrafast technique can rapidly provide volumetric mapping of plaques and clearly identify vulnerable plaques. By providing ultrafast imaging of arteries with high resolution and deep penetration depth simultaneously, this hybrid IVUS-OCT technology opens new and safe opportunities to evaluate in real-time the risk posed by plaques, detect vulnerable plaques, and optimize treatment decisions.", "publicationTitle": "Scientific Reports", "publisher": "", "place": "", "date": "2015", "volume": "5", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "18406", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Sci Rep", "DOI": "10.1038/srep18406", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "2045-2322", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "eng", "libraryCatalog": "PubMed", "callNumber": "", "rights": "", "extra": "PMID: 26678300\nPMCID: PMC4683418", "tags": [], "collections": [], "relations": {}, "dateAdded": "2016-01-04T21:57:34Z", "dateModified": "2016-01-04T21:57:34Z" } }, { "key": "3MXKNJVP", "version": 2, "library": { "type": "group", "id": 454820, "name": "Groupe 8 Yang, Takka, El Mamouni, Delimi", "links": { "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/454820/items/3MXKNJVP", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi/items/3MXKNJVP", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/454820/items/WRX3HN6C", "type": "application/json" } }, "meta": { "createdByUser": { "id": 2844797, "username": "elias.takka", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/elias.takka", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "3MXKNJVP", "version": 2, "parentItem": "WRX3HN6C", "itemType": "note", "note": "Recherche à partir de la base de donnée du portail paris sud puis redirection vers PubMed avec les mots-clés \"ultrafast ultrasound\"

However, the diffraction-limit can be overcome by super-localizing single events from isolated sources. In recent years, we developed plane-wave ultrasound allowing frame rates up to 20 000 fps. Ultrafast processes such as rapid movement or disruption of ultrasound contrast agents (UCA) can thus be monitored, providing us with distinct punctual sources that could be localized beyond the diffraction limit. We previously showed experimentally that resolutions beyond λ/10 can be reached in ultrafast ultrasound localization microscopy (uULM) using a 128 transducer matrix in reception. Higher resolutions are theoretically achievable and the aim of this study is to predict the maximum resolution in uULM with respect to acquisition parameters (frequency, transducer geometry, sampling electronics). The accuracy of uULM is the error on the localization of a bubble, considered a point-source in a homogeneous medium. The proposed model consists in two steps: determining the timing accuracy of the microbubble echo in radiofrequency data, then transferring this time accuracy into spatial accuracy. The simplified model predicts a maximum resolution of 40 μm for a 1.75 MHz transducer matrix composed of two rows of 64 elements. Experimental confirmation of the model was performed by flowing microbubbles within a 60 μm microfluidic channel and localizing their blinking under ultrafast imaging (500 Hz frame rate). The experimental resolution, determined as the standard deviation in the positioning of the microbubbles, was predicted within 6 μm (13%) of the theoretical values and followed the analytical relationship with respect to the number of elements and depth. Understanding the underlying physical principles determining the resolution of superlocalization will allow the optimization of the imaging setup for each organ. Ultimately, accuracies better than the size of capillaries are achievable at several centimeter depths.", "publicationTitle": "Physics in Medicine and Biology", "publisher": "", "place": "", "date": "Nov 21, 2015", "volume": "60", "issue": "22", "section": "", "partNumber": "", "partTitle": "", "pages": "8723-8740", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "Phys Med Biol", "DOI": "10.1088/0031-9155/60/22/8723", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1361-6560", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "eng", "libraryCatalog": "PubMed", "callNumber": "", "rights": "", "extra": "PMID: 26509596", "tags": [], "collections": [], "relations": {}, "dateAdded": "2016-01-04T21:57:32Z", "dateModified": "2016-01-04T21:57:32Z" } }, { "key": "I5MASUKN", "version": 2, "library": { "type": "group", "id": 454820, "name": "Groupe 8 Yang, Takka, El Mamouni, Delimi", "links": { "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/454820/items/I5MASUKN", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi/items/I5MASUKN", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/454820/items/8AZXAAUN", "type": "application/json" } }, "meta": { "createdByUser": { "id": 2844797, "username": "elias.takka", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/elias.takka", "type": "text/html" } } } }, "data": { "key": "I5MASUKN", "version": 2, "parentItem": "8AZXAAUN", "itemType": "attachment", "linkMode": "linked_url", "title": "PubMed entry", "accessDate": "2016-01-04T21:49:52Z", "url": "http://www.ncbi.nlm.nih.gov/pubmed/26248323", "note": "", "contentType": "text/html", "charset": "", "tags": [], "relations": {}, "dateAdded": "2016-01-04T21:57:29Z", "dateModified": "2016-01-04T21:57:29Z" } }, { "key": "KHKBS5DX", "version": 2, "library": { "type": "group", "id": 454820, "name": "Groupe 8 Yang, Takka, El Mamouni, Delimi", "links": { "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/454820/items/KHKBS5DX", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/groupe_8_yang_takka_el_mamouni_delimi/items/KHKBS5DX", "type": "text/html" }, "up": { "href": "https://api.zotero.org/groups/454820/items/8AZXAAUN", "type": "application/json" } }, "meta": { "createdByUser": { "id": 2844797, "username": "elias.takka", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/elias.takka", "type": "text/html" } } }, "numChildren": 0 }, "data": { "key": "KHKBS5DX", "version": 2, "parentItem": "8AZXAAUN", "itemType": "note", "note": "Recherche à partir de la base de donnée du portail paris sud puis redirection vers PubMed avec les mots-clés \"ultrafast ultrasound\"

Ultrafast ultrasound imaging, a unique ultrahigh frame rate technique (>10, 000 images/s), recently emerged enabling direct measurement of carotid PWV and its variation over the cardiac cycle. Our goal was to characterize the carotid diastolic-systolic arterial stiffening using ultrafast ultrasound imaging in healthy individuals and in vascular Ehlers-Danlos syndrome (vEDS), in which collagen type III is defectuous.\nMETHODS: Ultrafast ultrasound imaging was performed on common carotids of 102 healthy individuals and 37 consecutive patients with vEDS. Results are mean ± standard deviation.\nRESULTS: Carotid ultrafast ultrasound imaging PWV in healthy individuals was 5.6 ± 1.2 in early systole and 7.3 ± 2.0 m/s in end systole, and correlated with age (r = 0.48; P < 0.0001 and r = 0.68; P < 0.0001, respectively). Difference between early and end-systole PWV increased with age independently of blood pressure (r = 0.54; P < 0.0001). In patients with vEDS, ultrafast ultrasound imaging PWV was 6.0 ± 1.5 in early systole and 6.7 ± 1.5 m/s in end systole. Carotid stiffness change over the cardiac cycle was lower than in healthy people (0.021 vs. 0.057 m/s per mmHg; P = 0.0035).\nCONCLUSION: Ultrafast ultrasound imaging can evaluate carotid PWV and its variation over the cardiac cycle. This allowed to demonstrate the age-induced increase of the arterial diastolic-systolic stiffening in healthy people and a lower stiffening in vEDS, both characterized by arterial complications.

However, this technique only focuses on the propagation of the axial displacement of the artery wall, and most techniques are not specific to the intima-media complex and do not take into account the longitudinal motion of this complex. Within this perspective, this paper presents a study of two-dimensional tissue motion estimation in ultrafast imaging combining transverse oscillations, which can improve motion estimation in the transverse direction, i.e., perpendicular to the beam axis, and a phase-based motion estimation. First, the method was validated in simulation. Two-dimensional motion, inspired from a real data set acquired on a human carotid artery, was applied to a numerical phantom to produce a simulation data set. The estimated motion showed axial and lateral mean errors of 4.2 ± 3.4 μm and 9.9 ± 7.9 μm, respectively. Afterward, experimental results were obtained on three artery phantoms with different wall stiffnesses. In this study, the vessel phantoms did not contain a pure longitudinal displacement. The longitudinal displacements were induced by the axial force produced by the wall's axial dilatation. This paper shows that the approach presented is able to perform 2-D tissue motion estimation very accurately even if the displacement values are very small and even in the lateral direction, making it possible to estimate the pulse wave velocity in both the axial and longitudinal directions. This demonstrates the method's potential to estimate the velocity of purely longitudinal waves propagating in the longitudinal direction. Finally, the stiffnesses of the three vessel phantom walls investigated were estimated with an average relative error of 2.2%.", "publicationTitle": "IEEE transactions on ultrasonics, ferroelectrics, and frequency control", "publisher": "", "place": "", "date": "Jun 2015", "volume": "62", "issue": "6", "section": "", "partNumber": "", "partTitle": "", "pages": "1047-1058", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "IEEE Trans Ultrason Ferroelectr Freq Control", "DOI": "10.1109/TUFFC.2014.006910", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1525-8955", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "eng", "libraryCatalog": "PubMed", "callNumber": "", "rights": "", "extra": "PMID: 26067039", "tags": [], "collections": [], "relations": {}, "dateAdded": "2016-01-04T21:57:25Z", "dateModified": "2016-01-04T21:57:25Z" } } ]
