Multimode image based surgical operation navigation system

Abstract

The invention relates to a multimode image based surgical operation navigation system which comprises a preoperative image acquisition device, an ultrasonic scanning device, a multimode image registration device, an integrated endoscopic device and a postoperative evaluation device. The preoperative image acquisition device acquires a three-dimensional image, the ultrasonic scanning device acquires an ultrasonic image in real time, the multimode image registration device registers the three-dimensional image with the ultrasonic image to obtain a registered image, the integrated endoscopic device acquires current image information of an operational position during operation, and the multimode image registration device fuses the registered image and the current image information to obtain a fused image. The preoperative three-dimensional image, the intraoperative ultrasonic image and the intraoperative current image are fused, therefore, real-time image information which is accurate, reliable and rich in information content can be provided for doctors; meanwhile, by the aid of the postoperative evaluation device, bases are provided for subsequent disease diagnosis, tracking or operation implementation.

Description

【Technical field】 [0001] The invention relates to the field of medical instruments, in particular to a surgical operation navigation system based on multi-mode images. 【Background technique】 [0002] Computed Tomography (Computed Tomography, CT), Magnetic Resonance Imaging (Magnetic Resonance Imaging, MRI) and Ultrasound Imaging (Ultrasound, US) are widely used in computer-aided diagnosis and surgical navigation technology due to their respective characteristics and advantages. In the process of traditional minimally invasive surgery, the lack of accurate description of the three-dimensional structure of the lesion before operation directly affects the accuracy of preoperative planning. The safety and accuracy of spatial conception and speculation to comprehensively determine the specific location of the lesion will be affected subjectively, and severe cases will lead to surgical failure. [0003] With the aid of computer, the surgical navigator processes the image data suc...

Problems solved by technology

[0004] The surgical navigation system in the prior art lacks a set of composite detection and navigation solutions that combine preoperative imaging and intraoperative imaging, so that it cannot provide doctors with accurate, reliable, and informative real-time image information, and the quality of surgery cannot be further improved.

In addition, the surgical navigator in the prior art is not an open platform, and the software system and interface can only be operated according to the standards of each manufacturer's instrument, and cannot be updated, and basically do not have postoperative tracking analysis and evaluation functions, so there are It is necessary to establish an image-guided open and postoperative evaluation system, which can not only provide medical staff with a postoperative historical data reference platform, but also provide a basis for subsequent disease diagnosis, tracking, or surgical implementation based on historical surgical data. platform
