WebOct 20, 2024 · Coherence-based adaptive imaging The quality of an ultrasonic image is degraded by phase aberrations from an inhomogeneous distribution of sound speeds in a biological tissue. The coherence factor (CF) [ 7, 8, 9] was developed for evaluation of such degradation in image quality. WebOptical coherence tomography, or OCT, is an imaging method used to generate a picture of the back of your eye, called your retina. The noninvasive method produces an image …
WebJun 1, 2024 · Lastly, coherence imaging introduces artifacts not seen in B-mode imaging. Though some of these artifacts, such as the dark-region artifact, are well characterized in the literature (Dahl et al. 2024), they are not widely recognizable to sonographers and clinicians unfamiliar with coherence-based techniques. Without proper training to identify ... WebApr 1, 2024 · This work tries to achieve the image quality of TFM and M-PWI with a single plane-wave insonification to provide ultra-fast imaging at frame rates of tens of KHz. This is achieved by weighting the plane wave image with a phase coherence factor that keeps in-focus indications and suppresses spurious signals.
WebHe has developed groundbreaking physical methods for high-resolution 3D imaging of nanoscale materials and biological specimens. He pioneered coherent diffraction imaging ( CDI ), a lensless imaging (or computational microscopy) technique that is under rapid development worldwide.
One of the most important tasks in holography is phase recovery, as an opto-electronic sensor is only sensitive to the intensity of impinging light. The specifics of the phase recovery process depend on the holographic encoding strategy used, one of which is in-line holography, where the sample wave and … See more A recent work5 further demonstrated the ability of a trained deep neural network to perform simultaneously autofocusing and phase recovery to … See more In addition to the reconstruction of holograms, deep learning has also been used to perform resolution enhancement in coherent imaging … See more The applications of deep learning in coherent imaging systems are not limited to holography, which is based on the assumption of a single-scattering event.
