Abstract

A technique to display digitally sampled RF A-lines using false color is described. The backscattered 5 MHz ultrasonic signal obtained from the constant laminar flow of a blood-mimicking substance is sampled at 50 MHz with an 8 bit A/D converter. The RF samples of each backscattered A-line are displayed vertically and consecutive A-lines are displayed side-by-side horizontally to form a 2D false color image. The 2D image of a typical blood flow phantom data set is used to graphically demonstrate the manner in which conventional Doppler processing and newer correlation processing concepts are related to patterns in the 2D M-mode RF display.
