A system for ultrasound examination configured to examine whether or not a lesion exists, based on a dynamic image comprised of a plurality of frame arrays that are temporally continuous and are output from an ultrasound examination apparatus with an ultrasonic probe being manipulated, the system comprising: a reference data storage operable to store reference data for determining normality that are obtained by extracting cubic higher-order local autocorrelation features from a plurality of frames that constitute a dynamic image of a human body part where a lesion does not exist as obtained from a reference examinee or an examinee with an ultrasonic probe being manipulated at a speed within a predetermined speed range and analyzing extraction results by a predetermined analyzing method, a frame checker including: a feature extractor operable to extract cubic higher-order local autocorrelation features from each of a plurality of frames that constitute a dynamic image of a human body part as obtained from the ultrasound examination apparatus when an examiner manipulates the ultrasonic probe on the examinee, and a state determinator operable to determine whether a frame in question is a normal frame not containing the lesion or an abnormal frame containing the lesion, based on extraction results of cubic higher-order local autocorrelation features from each frame and the reference data for determining normality; a speed information acquirer operable to acquire speed information on a speed of the ultrasonic probe manipulated by the examiner in respect of each frame; and a speed determinator operable to determine that the speed of the ultrasonic probe, which has been obtained from the speed information acquired by the speed information acquirer, is a normal speed when the speed of the ultrasonic probe does not exceed a threshold predefined with reference to the predetermined speed range, wherein: the state determinator in the frame checker determines that the frame in question is the normal frame when the speed determinator determines that the speed of the ultrasonic probe is not the normal speed even though the frame in question can be determined as the abnormal frame, based only on the extraction results of cubic higher-order local autocorrelation features from each frame and the reference data for determining normality. a reference data storage operable to store reference data for determining normality that are obtained by extracting cubic higher-order local autocorrelation features from a plurality of frames that constitute a dynamic image of a human body part where a lesion does not exist as obtained from a reference examinee or an examinee with an ultrasonic probe being manipulated at a speed within a predetermined speed range and analyzing extraction results by a predetermined analyzing method, a frame checker including: a feature extractor operable to extract cubic higher-order local autocorrelation features from each of a plurality of frames that constitute a dynamic image of a human body part as obtained from the ultrasound examination apparatus when an examiner manipulates the ultrasonic probe on the examinee, and a state determinator operable to determine whether a frame in question is a normal frame not containing the lesion or an abnormal frame containing the lesion, based on extraction results of cubic higher-order local autocorrelation features from each frame and the reference data for determining normality;
