Abstract: The ultrasound examination system automatically detects a lesion, based on a dynamic image including a plurality of frame arrays that are temporally continuous and are output from the ultrasound examination apparatus with an ultrasonic probe being manipulated. Detection accuracy of the ultrasound examination system can be increased. A feature extractor in a frame checker extracts cubic higher-order local autocorrelation features from each frame of a plurality frames that constitute a dynamic image of a human body part as obtained from an ultrasound examination apparatus while an examiner manipulates an ultrasonic probe on the examinee. A final determinator determines that the frame in question is a normal frame when a speed determinator determines that the speed of the ultrasonic probe is not a normal speed even though the frame in question can be determined as an abnormal frame containing a lesion.
