Title:
An ultrasound test system and an ultrasonic inspection method
Document Type and Number:
Japanese Patent JP6281994
Kind Code:
B2
Abstract:
The ultrasound examination system automatically detects a lesion, based on a dynamic image comprised of 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 71 in a frame checker 7 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 3 while an examiner manipulates an ultrasonic probe 1 on the examinee. A final determinator 75 determines that the frame in question is a normal frame when a speed determinator determines that the speed of the ultrasonic probe 1 is not a normal speed even though the frame in question can be determined as an abnormal frame containing a lesion.
