Claim 0:
1. An ultrasound diagnostic apparatus comprising:
at least one processor which when executing a program configures the processor to:
detect a lesion included in an ultrasonic image which is a real-time video image, and that outputs lesion information when the lesion is detected; and
cause a mark for indicating the lesion to be displayed on the ultrasonic image based on the lesion information, and restrict display of the mark when a mark display restriction condition is satisfied by a continued detection of the lesion;
delete the mark from the ultrasonic image when the mark display restriction condition is satisfied even if the lesion continues to be detected; and
judge that the mark display restriction condition is satisfied, based on the lesion information,
wherein the lesion information includes position information which shows a position of the lesion, and size information which shows a size of the lesion,
wherein the at least one processor is further configured to judge that the mark display restriction condition is satisfied, based on at least one of the position information and the size information of the lesion, and
wherein the mark display restriction condition includes a first condition, a second condition, and a third condition, the first condition being a condition of determining that detection of the lesion is continued over n frames, where n is an integer greater than or equal to m, the second condition is a condition of determining that the amount of movement of a center coordinate of the lesion between the reference frame and the current frame is within a second range, the third condition being a condition of determining that the amount of change of the size of the lesion between the reference frame and the current frame is within a third range, and when all of the first, second and third conditions are simultaneously satisfied, the mark is not displayed on the screen.
