PURPOSE:To provide the ultrasonic diagnostic system which can represent even a small lesion part and also represent even fine size variation of the lesion part in three dimensions and is suitable for early-stage detection and development observation. CONSTITUTION:This system is provided with an image data acquisition means (ultrasonic probe 10, electronic switch circuit 12, transmission and reception parts 13 and 14, controller 15, and three-dimensional image composition part 6) which obtains data of a 1st three-dimensional image of a diagnostic part of a patient P by scanning the diagnostic part in three dimensions with an ultrasonic wave beam, a difference detecting means (database part 17, image deviation correction part 18, and inter-pixel subtraction part 19) which detects differences in shape between the 1st three-dimensional image and a 2nd three- dimensional image obtained as to the past identical diagnosed part of the same sample, and a display means (display part 20) which displays an image based upon shape difference information. |
