Ultrasonic navigation system and method

Abstract

The invention provides an ultrasonic navigation system and method, and relates to the technical field of ultrasonic assisted scanning. The ultrasonic navigation system comprises ultrasonic equipment used for performing scanning to obtain a target section image, a pose acquisition device used for acquiring real-time pose information of an ultrasonic probe, and a data processing device used for processing the target section image according to a standard section image to obtain offset position information. During the first scanning, the offset position information is fed back to the ultrasonic equipment as the current offset data of the ultrasonic probe, and an operator adjusts the scanning position according to the current offset data, carries out processing to obtain current offset data ofthe current scanning position according to the offset position information and the real-time pose information of the current scanning position and the offset position information and the real-time pose information of the previous scanning position, and feeds back the current offset data to the ultrasonic equipment until the current offset data meets a preset offset threshold value, thereby finishing a scanning navigation process. The system and the method have the advantages that real-time ultrasonic navigation information is provided for operators, and dependence on ultrasonic scanning experience of the operators is not needed.

Description

technical field [0001] The invention relates to the technical field of ultrasound-assisted scanning, in particular to an ultrasound navigation system and method. Background technique [0002] Ultrasound imaging is a medical imaging technique that uses high-frequency sound waves to observe structures in living organisms. Because ultrasound images are collected in real time, ultrasound images can also show the movement of internal organs and blood flow through the body, as well as tissue stiffness. Unlike x-ray imaging, ultrasound imaging does not involve ionizing radiation, thus enabling extended use of ultrasound imaging without the damage to tissues and internal organs caused by prolonged radiation exposure. Ultrasound images are made by measuring the reflection of ultrasound waves off structures in the body. The strength of the ultrasound signal and the time it takes for the sound waves to travel in the body provide the information necessary to calculate the image. [0...
