Abstract

Sound-speed images can be used for cancer detection and diagnosis. In soft tissues, tumors have generally different sound speeds than normal tissues. Improving ultrasound image quality and variety of imaged tissue properties should prove beneficial to breast cancer screening and diagnosis. The goal of this study is to compare the effect of five reconstruction filters on fan beam acquisition modes of ultrasound computed Tomography (UCT) and investigate the image quality parameters of the point spread function (PSF), modulate transform function (MTF) and spatial resolution for two different arrangements of ultrasonic array, ring-shaped and parallel shaped. These study results show that the spatial resolution affected by not only detector arrangement but also reconstruction filters.
