PROBLEM TO BE SOLVED: To provide an ultrasonic display equipment that can quantitatively evaluate the ventricle motions by arranging a frame comparison means and a mapping function allotting means in an ultrasonic heart imaging device, spatially in a device that accurately images the ventricle motions. SOLUTION: Output signals of scanner 10 that scans a special area of a patient body such as a heart by ultrasonic waves are inputted into a frame memory 13 through a scan converter 12, and are displayed in a displayer 14 while collecting the data. At this time, in a sound quantifying unit 30, each pixel points are classified whether it is a blood pixel point or is a tissue pixel point and whether it appears in a diastole or in a contraction. Namely, the sound quantifying unit 30 is equipped with a frame comparison means that judges the pixel points changing to different type images, and a mapping function allotting means that allots the mapping function in order to easily distinguish the changed pixel points. |
