Abstract

PROBLEM TO BE SOLVED: To allow an ultrasonograph to perform image measuring functions with accurate measurements near the lowest resolution. SOLUTION: A cruciform measuring cursor 5 is displayed on the grid point closest to indicating coordinates and on the grid point next closest thereto as it is superimposed on an ultrasonogram 4 on the display 3 of this ultrasonograph. A measuring cursor display brightness control means 8 varies the display brightness ratio of the measuring cursor 5 according to a division ratio between the grid points. A point intermediate between the grid points or the position of one of the grid points is used as measuring cursor position information. The above operation is performed twice to provide a numerical display 10 of the distance measurement between two points on the ultrasonogram 4, etc. Thus, the position resolution of the measuring cursor 5 can be more than doubled.

Since there is a deviation between the center of the ultrasonic image 4 having the multi-gradation luminance information and the measurement cursor 5, the cursor movement instructing means on the console 6 is slightly moved to the right (for example, the minimum cursor movement distance is 0.5 mm).
