ULTRASOUND DIAGNOSTIC APPARATUS AND OPERATION METHOD OF ULTRASOUND DIAGNOSTIC APPARATUS

摘要

An ultrasound diagnostic apparatus includes: a beam former that drives an ultrasound transducer including two-dimensionally arranged vibration elements and that acquires ultrasound data of a three-dimensional space; a delay calculating circuit sets scan conditions including a drive delay amount of the beam former; a graphic circuit that generates an ultrasound slice image of a predetermined cut surface from the ultrasound data of the three-dimensional space; and a CPU that determines a focal length or a focal depth of the ultrasound according to a distance from the ultrasound transducer to the desirably set cut surface to set an amount of delay to cause the delay calculating circuit to change the scan conditions.

1. An ultrasound diagnostic apparatus that performs scanning with ultrasound, the ultrasound diagnostic apparatus comprising:
an ultrasound transducer including two-dimensionally arranged ultrasound vibration elements; a scanning section that drives the ultrasound transducer to generate the ultrasound and transmit the ultrasound for scanning in a three-dimensional space, and acquires ultrasound data of the three-dimensional space from the ultrasound received; a scan condition setting section that sets scan conditions of the scanning section including an amount of delay related to drive timing of the ultrasound vibration elements; a slice image generating section that generates an ultrasound slice image of a predetermined cut surface in the three-dimensional space from the ultrasound data of the three-dimensional space; a cut surface setting section that sets the cut surface at a desired position; and a control section that performs control of changing the scan conditions set by the scan condition setting section according to the cut surface set by the cut surface setting section, wherein the control section determines a focal length of the ultrasound or a focal depth of the ultrasound according to a distance from the ultrasound transducer to the cut surface and sets the amount of delay based on the determined focal length or focal depth.
