ULTRASOUND DIAGNOSTIC DEVICE, MEDICAL IMAGE PROCESSOR AND MEDICAL IMAGE PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic device capable of determining a perfusion response characteristic in an object region on the basis of a time intensity curve.SOLUTION: The ultrasound diagnostic device includes: transmission/reception sections 111, 112 which transmit/receive ultrasonic waves to/from an analyte to whom a contrast agent is administrated via an ultrasonic transducer; a volume data generation section which generates a series of volume data in time sequence on the basis of outputs from the transmission/reception sections; a curve determination section which determines a time intensity curve of each of multiple voxels in the volume data on the basis of the volume data; a setting section which sets an object voxel to be an analysis object of perfusion response characteristics and a transit-related voxel which is positioned at a different location from the object voxel; and a response characteristics determination section which determines the perfusion response characteristics on the basis of the time intensity curve in each of the transit-related voxel and the object voxel.
