WebSep 9, 2024 · Abstract: The point spread function (PSF), namely the response of an ultrasound system to a point source, is a powerful measure of the quality of an imaging system. The lack of an analytical formulation inhibits many applications ranging from apodization optimization, array-design, and deconvolution algorithms. WebApr 11, 2024 · An extra loss function must be added to the generator to generate images near the ground truth. In this work, a PSNR served as the loss function of the generator: (6) L psnr G = E x − 10 ⋅ log 10 M A X 2 / M S E y, G x where MAX denotes the maximum pixel value of the image; thus, the final objective function is: (7) L pix 2 pix = min G max D L G, D + λ L …

WebIts mathematical description is Point Spread Function (PSF), which expresses the normalized intensity distribution of the point-source image (it should be noted that this diffraction PSF is different from the geometrical PSF, which is based on the distribution of rays in point image). WebFeb 26, 2024 · Axial resolution in ultrasound refers to the ability to discern two separate objects that are longitudinally adjacent to each other in the ultrasound image. Axial resolution is generally around four times better than lateral resolution.. Axial resolution is defined by the equation: axial resolution = ½ ⨉ spatial pulse length.The spatial pulse … WebBlind deconvolution of ultrasound image using a parametric model for the PSF (Major Investigator).
