Problems solved by technology

[0009] That is, in the ultrasonic diagnostic apparatus described in Japanese Patent Application Laid-Open No. 11-290318, when the display area of ​​the ultrasonic image displayed when each mode is executed is changed to a display area desired by the operator, since the focus position does not match, Therefore, a high-definition ultrasonic image cannot be displayed, and in order to make the focus position consistent, it is necessary to use the operation part to adjust, so there are problems such as troublesome and difficult to handle.

Abstract

An ultrasound diagnostic apparatus 1 includes a transmission section 11 which is transducer drive means capable of transmitting ultrasound at a predetermined focus position from an ultrasound transducer 2a, and a CPU 5 which is display region changing means capable of changing a display region to be displayed on a monitor 8 in an ultrasonic image; and controls the transmission section 11, which is the transducer driving means, in accordance with the change result to change the focus position of the ultrasound.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus capable of changing a focus position of an ultrasonic image according to the changed display area when changing a display area of ​​an ultrasonic image, and a focus position control method of the ultrasonic diagnostic apparatus. Background technique [0002] In recent years, ultrasonic diagnostic devices have been widely used in medical and industrial fields. An ultrasonic diagnostic device repeatedly transmits ultrasonic waves from an ultrasonic vibrator to living tissue, receives echo signals of ultrasonic waves reflected from living tissue, and displays information in the living body as an ultrasonic tomographic image (hereinafter simply referred to as an ultrasonic image) as a visible image. . [0003] In particular, electronic scanning ultrasonic diagnostic devices that electronically drive ultrasonic vibrators to scan the body cavity can freely change the scanning method, and ca...
