AmCAD-US is a software device intended to visualize and quantify the statistical distributions of backscattered signals echoed by tissue compositions in the body from FDA-cleared ultrasound systems. The device provides dual mode images, including conventional B-mode ultrasound images in gray scale and color-mapped US (ultrasound structure) mode images. The US-mode provides a means for viewing and displaying the backscatter statistical values. The information may be useful in assisting interpretation of variation in tissue states of any scanned tissues.
