Therefore, ultrasound enhancement methods usually include nonlinear, adaptive or multiscale algorithms. Lichtensten, B. part of the original image has been cropped. By transmitting acoustic energy into the body and receiving and processing the returning reflections, phased-array ultrasound systems can generate images of internal organs and structures, map blood flow and tissue motion, and provide highly accurate blood velocity information. Although, these systems produce good three-dimensional images, they are far from real time, often requiring minutes to construct. Conclusions.Adaptive processing provided better image quality without loss of clinically useful information. Post-processing steps that include building image descriptors and a spatial pyramid matching (SPM) algorithm are performed. Answered: Image Analyst on 10 May 2020 Accepted Answer: Ameer Hamza.
