Ultrasound diagnostic apparatus

Abstract

An ultrasound diagnostic apparatus (1) having a plurality of transducer groups (31 and 32) which are provided at a distal end portion of a probe (20a), and are configured by a plurality of transducers arranged in a circumferential form or an arc form having a same radius of curvature, and a common sound ray synthesis table (43) storing control data of the respective transducer groups (31 and 32).

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus, and more particularly to an ultrasonic diagnostic apparatus provided with an ultrasonic endoscope having a plurality of transducer groups scanning in mutually orthogonal planes at the distal end of a probe. Background technique [0002] In recent years, a method of inserting an ultrasonic endoscope into a living body, discovering a lesion in the body from its optical image, irradiating ultrasonic waves, and diagnosing ultrasonic tomographic images of the lesion from the reflected waves has become widespread. In addition, the following method is also implemented, using a puncture needle under the guidance of an optical image / ultrasound tomographic image, visually identifying and performing puncture to absorb cells, and confirming the diagnosis by absorbing cells. [0003] When making such a diagnosis, it is necessary to collect the tissue accurately, and as a collection method, there a...

Problems solved by technology

[0006] The biplanar ultrasonic diagnostic devices using two transducer groups disclosed in Japanese Patent Application Laid-Open No. 8-56948 and Japanese Patent Laid-Open No. 2004-135693 require separate sound ray synthesis tables and transmission and reception tables corresponding to each transducer group. part and image generation part, etc., the device structure becomes complicated

[0007] In addition, in the ultrasonic diagnostic apparatus disclosed in Japanese Patent Laid-Open No. 2002-177278, only a probe using a plurality of vibrator groups having the same shape and driving method is disclosed, and the same control device, etc. are used for switching.
