Three-dimensional spatial positioning system for medical ultrasonic probe relative to part to be checked and method

Abstract

The invention discloses a three-dimensional spatial positioning system for a medical ultrasonic probe relative to a part to be checked, which comprises an image acquisition module, an ultrasonic probe, a communication module and a computer module. The inside or surface of the ultrasonic probe is provided with a three-axis gyroscope. In a specific positioning method, video signals of the probe on a specific anatomical part of a human body are obtained through the image acquisition module, the three-axis gyroscope is used for determining the state of the three-dimensional space with the ultrasonic probe, and the communication module is used for respectively transmitting data obtained by the three-axis gyroscope and the image acquisition module to the computer module; and the computer module is used for processing the video signals of the probe on the specific anatomical part obtained through the image acquisition module and information on the state of the space with the probe sensed by the three-axis gyroscope, and promptly and synchronously displaying the information on a screen. The defect of no probe information in the current ultrasonic diagnosis can be overcome, and necessary diagnostic information can be provided for ultrasonic diagnosis.

Description

technical field [0001] The invention relates to a three-dimensional space position information positioning system of a medical ultrasonic probe, includes the specific application of space positioning technology, and belongs to the field of medical equipment. Background technique [0002] With the development of modern medical imaging technology, the help of ultrasonic imaging diagnosis to clinical disease diagnosis is becoming more and more significant. For ultrasound diagnosis, image quality is of course very important. However, ultrasound images are partial tomographic images of the human body, and there is no positioning map similar to CT and MRI examinations. It is impossible to judge the cross-section of which part this picture is. If the spatial position information of the ultrasonic probe to the examination site can be provided at the same time, such as the position of the probe center on the body surface and the spatial angle relationship, the diagnostician can acc...
