Wireless curved plane extended field-of-view ultrasound imaging method and device

Abstract

The invention discloses a wireless curved plane extended field-of-view ultrasound imaging method and a wireless curved plane extended field-of-view ultrasound imaging device. The method comprises the steps: 1) when an ultrasound probe rotates for any angle during image acquisition, obtaining the rotating angle, the acceleration and the moving direction of the ultrasound probe, and inputting the rotating angle, the acceleration and the moving direction together with ultrasound images obtained at the moment into a computer for processing through a wireless positioning device; 2) taking an initial measurement position as an original space point, establishing a space rectangular coordinate system through a first frame of image and then sequentially obtaining coordinate values of each frame of image in the coordinate system; 3) displaying the images according to the obtained space rectangular coordinate system to realize curved plane extended field-of-view ultrasound imaging. The device comprises the computer and the ultrasound probe, wherein the wireless positioning device is arranged on the ultrasound probe, and the ultrasound probe and the wireless positioning device are respectively connected with the computer. The method and the device disclosed by the invention have the advantages that the flexibility of ultrasound probe scanning is improved and the large-angle bent tissue imaging effect is more ideal.

Description

technical field [0001] The invention relates to a medical ultrasonic wide-view imaging method, in particular to a wireless curved-surface ultrasonic wide-view imaging method and device, and belongs to the technical field of medical ultrasonic wide-view imaging. Background technique [0002] Medical ultrasound imaging is one of the important diagnostic methods in modern clinical medicine. Since traditional ultrasound probes can only generate ultrasound images with a narrow field of view and cannot reflect the overall image of the detected area, it has a certain degree of impact on the accuracy and rapidity of medical diagnosis. influences. To solve this problem, Extended field-of-view ultrasound was proposed by Weng et al. in 1996. It collects a series of ultrasound images and stitches them together in real time using image registration technology to form a larger field of view. image, which is convenient for doctors to diagnose. [0003] In clinical operations, traditional...

Problems solved by technology

When detecting tissues with a large degree of curvature, the imaging results of traditional wide-field imaging technology are quite different from the actual situation. The method usually used is a serpentine trajectory ultrasonic wide-field imaging method (see published patents for details: A serpentine trajectory ultrasonic wide-view imaging method, publication number: CN102166122A), this method is to collect a series of ultrasonic images and their position information, and then transform these images into a world coordinate system according to the position information for wide-view imaging, but the space calibration and coordinate transformation process of this method is time-consuming
