Problems solved by technology

However, due to the deep location and small size of the lesion, it is usually impossible to accurately locate the position, depth and direction of the puncture through the body surface, which will cause problems such as misdiagnosis and missed diagnosis.
At present, ultrasound imaging is the most widely used intraoperative real-time imaging method for puncture guidance. It has the advantages of simple operation and good real-time performance, but its disadvantages are low resolution, large image noise, low tissue and organ differentiation, and a single imaging method.
Magnetic resonance imaging has high resolution and can provide a variety of imaging methods, with a high degree of di

Abstract

The invention discloses a real-time puncture navigation system, which comprises a puncture needle; a host computer to display puncture navigation space of a multimodal image based on the fusion of a magnetic resonance image prior to a surgery and an ultrasonic image during the surgery; an ultrasonic detecting device comprising an ultrasonic probe and an ultrasonic imaging apparatus wherein the ultrasonic probe sends acquired ultrasonic data to the ultrasonic imaging apparatus for processing and outputs the ultrasonic image during the surgery for display and transmission to the host computer; a space registering device comprising a magnetic locator and a calibration body die wherein the magnetic locator receiver is fixedly arranged on the ultrasonic probe through a probe fixture, the calibration body die calibrates the corresponding positions of the magnetic locator receiver and the ultrasonic image plane during the surgery and the magnetic locator receiver acquires the space position of the ultrasonic probe so as to further obtain the space position of the ultrasonic image plane during the surgery; and reality augmented glasses in connection with the host machine and the puncture needle. According to the invention, no special ultrasonic probe and imaging apparatus are needed, making the system not limited to specific puncture parts, and achieving convenient and high puncture navigation.

Description

technical field [0001] The invention relates to the field of medical instruments, and more specifically, the invention relates to a real-time puncture navigation system and a navigation method thereof. Background technique [0002] With the development of medical technology, minimally invasive diagnosis and treatment have been more and more widely used in clinical practice, such as biopsy of prostate cancer and ablation of liver lesions. However, due to the deep location and small size of the lesion, usually the puncture through the body surface cannot accurately locate the position, depth and direction of the puncture, which will cause problems such as misdiagnosis and missed diagnosis. At present, ultrasound imaging is the most widely used intraoperative real-time imaging method for puncture guidance. It has the advantages of simple operation and good real-time performance, but its disadvantages are low resolution, high image noise, low tissue and organ differentiation, an...
