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 grayscale 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 the interpretation of variation in tissue states of any scanned tissues. Characteristics Real-time visualization for the assessment of tissue variation Quantification of the statistical distribution of the backscattered signals Adaptation of several patented statistical methods to analyze the ultrasonic signals Applications to clinical interpretation and diagnosis of various organs and diseases Acceleration and enhancement of imaging performance and quality by proprietary algorithms.
