explain the physics behind the production of an ultrasound image in language that is easy to understand and with ample illustrations. I think the perfect audience for this volume is a staff physi- cian who teaches ultrasound to radiology residents and ...
Emerging single-photon-sensitive sensors produce picosecond-accurate time-stamped photon counts. Applying advanced inverse methods to process these data has resulted in unprecedented imaging capabilities, such as non-line-of-sight (NLOS) imaging. Rather than imaging photons that travel along direct paths...
Ultrasound is used in breast imaging for differentiation of cysts from solid masses and to provide real-time guidance for interventional procedures. Breast... RJ Stafford,GJ Whitman - 《Ultrasound Clinics》 被引量: 11发表: 2011年 3D microwave tomography of the breast using prior anatomical informat...
PINNs take advantage of the governing physical laws behind the processes that generate the data, hence reducing greatly the reliance of the DNN on the labeled data during the training process. PINNs simply bridge the gap between data-scarcity and the data-intensive nature of DNNs and have been ...
the image produced behind the fluid-filled structure will appear bright compared to surrounding tissue. The hyperechoic signal may obscure detail in the tissue. A common application to illustrate posterior acoustic enhancement is bladder ultrasound, where time gain compensation must often be decreased to...

In case of convex mirror, the center of curvature lies behind the mirror. The radius of the sphere of which, the reflecting surface of a spherical mirror forms a part, is known as the radius of curvature of the mirror and represented by the English letter ‘R.’ Remember, the distance ...
