関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an ultrasound diagnostic device for use in a body cavity, and particularly relates to a tip configuration and ultrasound signal processing suitable for sharpening ultrasound images. be.
従来の体腔内用超音波診断装置は、超音波振動子は一種
類しか配設されておらず、そのため超音波画像の鮮明部
は診断面の近傍か遠方のどちらかでしかないという欠点
があった。Conventional intrabody cavity ultrasound diagnostic equipment has the disadvantage that only one type of ultrasound transducer is installed, and the clear part of the ultrasound image is either near or far from the diagnostic surface. Ta.
本発明の目的は、超音波画像で診断面近傍及び遠方とも
同時に鮮明に表示された画像を得ることができる体腔内
用超音波診断装置を提供することにある。An object of the present invention is to provide an intra-body cavity ultrasound diagnostic apparatus that can obtain ultrasound images that are clearly displayed near and far from a diagnostic surface at the same time.
超音波振動子の周波数・フォーカス点等のちがいにより
、その超音画像の診断部の鮮明な部分が異なることから
、一体腔内用超音波診断装置に２種類の振動子を配設し
、その表示画像を同時表示することにより、超音波画像
全体が鮮明となる。Due to differences in the frequency and focus point of the ultrasound transducer, the clear part of the diagnostic part of the ultrasound image differs, so two types of transducers are installed in an integrated intracavity ultrasound diagnostic device. By displaying the display images simultaneously, the entire ultrasound image becomes clear.

るものである。That is, the present invention includes a high-frequency ultrasonic transducer and an ultrasonic transducer having a lower frequency than the above-mentioned transducer and whose focus point is located further away than the above-mentioned transducer, at the distal end of the body cavity insertion part. This device is characterized by being equipped with two types of vibrators.

駆動軸１３・従動軸９によシラシアル回転運動をする。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 shows the configuration of an intracorporeal ultrasound diagnostic apparatus. 4 is an ultrasonic image drawing and ultrasonic pulse generation/reception device. The intrabody cavity ultrasound probe 1, which has a flexible tube 2 that can be freely inserted and removed into the body cavity, obtains information signals for depicting ultrasound images inside the body cavity, and transmits the information to the body cavity 4 via a cable 3. Input the signal. The information signal inputted here is obtained by the components shown in FIG. 2, which is an enlarged view of the tip of FIG. This means that 8.70 two ultrasonic transducers with different frequencies and focus points are used.
The drive shaft 13 and the driven shaft 9 cause sillial rotational movement.

び信号線１５・１４によって４に入力されるのである。Accordingly, image information can be obtained from the information signal for drawing a 180-degree cross-sectional ultrasound image of the diagnostic site at the frequency and focus point of each transducer. In other words, information signals for two images are obtained. It is inputted to 4 through 16 electrical signal transmitters and signal lines 15 and 14.

。The input signal is amplified and displayed on the screen of the CRT 5 as an ultrasonic image 6 in which two images are superimposed on each other. Here, the base point position signal for superimposing the two images is 16
Information is obtained from changes in the magnetic force caused by the electric signal transmitting body, and the information is transmitted to 4 through the signal line 18.
このように、本実施例は、−診断の時間で、２つの異な

報を提供できる効果がある。In this way, the present embodiment provides useful diagnosis by obtaining two different ultrasound images at the time of diagnosis, amplifying the information, and superimposing the two images into one image. It has the effect of providing information.
本発明によれば、診断面の超音波画像が、診断 ・部位
の近傍・遠方とも鮮明に表示できるため、有用性の高い
診断情報を一診断・一画面で得ることができる。According to the present invention, since the ultrasound image of the diagnostic plane can be clearly displayed both near and far from the diagnostic site, highly useful diagnostic information can be obtained in one diagnosis and on one screen.
