Mathematical Analysis of Ultrafast Ultrasound Imaging
This paper provides a mathematical analysis of ultrafast ultrasound imaging. This newly emerging modality for biomedical imaging uses plane waves instead of focused waves in order to achieve very high frame rates. We derive the point spread function of the system in the Born approximation for wave propagation and study its properties. We consider dynamic data for blood flow imaging, and introdu...
متن کاملUltrafast Ultrasound Imaging
Ultrasound can be considered as a disruptive technology in the medical device arena (Christensen, 2003). A disruptive technology has the potential to break the rules of existing markets. Thanks to its real time capabilities, its non ionizing properties and its cost much lower than any other medical modality ultrasound has significantly impacted clinical segments within radiology, obstetrics, va...
متن کامل3 D ultrafast ultrasound imaging in vivo
Very high frame rate ultrasound imaging has recently allowed for the extension of the applications of echography to new fields of study such as the functional imaging of the brain, cardiac electrophysiology, and the quantitative imaging of the intrinsic mechanical properties of tumors, to name a few, noninvasively and in real time. In this study, we present the first implementation of Ultrafast...

متن کاملUltrafast Ultrasound Imaging of Ocular Anatomy and Blood Flow
PURPOSE Ophthalmic ultrasound imaging is currently performed with mechanically scanned single-element probes. These probes have limited capabilities overall and lack the ability to image blood flow. Linear-array systems are able to detect blood flow, but these systems exceed ophthalmic acoustic intensity safety guidelines. Our aim was to implement and evaluate a new linear-array-based technolog...
