Multi-modal fusion surgical navigation system and method based on three-dimensional reconstruction

Abstract

The invention discloses a multi-modal fusion surgical navigation system and method based on three-dimensional reconstruction. The system comprises an image data preprocessing module, a pre-surgery planning module and a real-time surgical navigation module; the image data preprocessing module is used for the collection and processing of medical image data; the pre-surgery planning module performs multi-modal fusion of the processed medical image data to establish a pre-surgery lesion location model and plan a surgical path; and the real-time surgical navigation module establishes a dynamic model according to an intra-surgery four-dimensional ultrasound scan data, and compares the dynamic model with the pre-surgery lesion model to update the surgical path. The beneficial effects are: conducting fusion processing of different medical image data, integrating the advantages of each model, achieving information complementarity, and performing real-time comparison of the real-time establisheddynamic model with the pre-surgery lesion positioning navigation model, so as to make navigation more accurate. Accurate monitoring of the lesion changes is performed during the surgery process, so as to improve the accuracy and effect of interventional surgery.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a three-dimensional reconstruction-based multi-modal fusion surgical navigation system and method. Background technique [0002] Medical imaging has been an important source of clinical diagnostic information since its birth. With the vigorous development of medical imaging, it can provide more and more comprehensive diagnostic information for the clinic. According to the information content provided by medical images, anatomical structure images and functional images, these two types of images have their own advantages and disadvantages, and the resolution of functional images is poor, but the organ function and metabolism information it provides cannot be replaced by anatomical images; Anatomical images provide information on the anatomical shape of organs with high resolution, but cannot reflect the function of organs. [0003] With the development of technology, in the exi...
