Detailed Description of the Invention [Field of Industrial Application] This invention relates to an ultrasonic diagnostic apparatus that irradiates an object with ultrasound and obtains a tomographic image of the object from the reflected information. .

複数の横断層像を３次元表示している。As a conventional ultrasonic diagnostic device, Japanese Patent Application Laid-Open No. 58-70757
There was an ultrasonic diagnostic device described in the publication. This device uses an electronic scanning ultrasound probe installed outside the subject to electronically scan ultrasonic waves within the cross section of the subject, and uses the reflection information to scan one side of the subject. Obtain a tomographic image. Then, the ultrasound probe is moved in the longitudinal direction of the subject (secondary scanning), and a cross-sectional image of the subject is obtained at each secondary scanning position,
Multiple cross-sectional images are displayed in three dimensions.

空気や肋骨に邪魔されそ全での横断面内での心臓の断層
像は得られず、完全な３次元表示は不可能であった。Generally, ultrasound waves are attenuated while propagating through air or bone. In conventional ultrasonic diagnostic equipment, the ultrasonic probe is installed outside the body and irradiates the subject with ultrasonic waves from outside the body. A tomographic image of the heart could not be obtained, and a complete three-dimensional display was not possible.
また、超音波探触子を２次走査させるための大型の走査
機構が必要である欠点もあった。Another drawback is that a large scanning mechanism is required for secondary scanning of the ultrasonic probe.

触子と被検体との距離があり、超音波の周波数を上げら
れず分解能が悪かった。Furthermore, since ultrasound is irradiated onto the subject from outside the body, there is a distance between the probe and the subject, making it impossible to increase the frequency of the ultrasound and resulting in poor resolution.
この発明は上述した事情に対処すべくなされたもので、
その目的は超音波を高周波化でき、解像度の高い断層像

られる。According to the ultrasonic diagnostic apparatus according to the present invention, instead of conventional scanning from outside the body, ultrasonic waves are irradiated to the subject from within the body cavity. It is possible to obtain a tomographic image in a plane, resulting in a complete three-dimensional display, and since the ultrasound is irradiated from a part close to the subject, it is possible to achieve a higher frequency of ultrasound, thus increasing the resolution. You can also do it. Further, since the secondary scanning which changes the primary scanning section of the ultrasound is performed by the operator pulling out the endoscope, the secondary scanning mechanism is simple and safe. Furthermore, since the secondary scanning position is detected by a detector that detects the insertion depth of the endoscope and a tomographic image is captured in synchronization with the output of the electrocardiograph, accurate three-dimensional information can be obtained.
