Abstract

Ultrasonic scan data is displayed within a display (10) and is arranged in a plurality of two and three-dimensional colored displays (20, 30, 40, 50). A C-scan display (40) is a composite plot of a region of interest using color to designate echo amplitude. The composite plot (40) is time-gated to limit the range of depths of data presented and thereby limit the plot to a thin section such as a surface. Surface breaking discontinuities (100) are visible as highly colored echoes within this C-scan display (40). Within C-scan display (40), once a discontinuity such as a reflector is detected, additional gates (150-165) may be set which permit other specialized displays such as D-scan (50) and B-scan (20) windows to portray the discontinuities. The D-scan plots index direction (54) against time (52), and readily displays circumferential reflectors (130-145) therein, while also enabling rapid estimation of the depth (142) of these reflectors. A B-scan plot (20) which enables fine profilming of reflectors may be a single pane taken at a single axial location determined by an index cursor (168), or may alternatively be a composite plot. Various modifications to the basic system are disclosed that further enhance the utility of the display (10).
