A three-dimensional renal tumor surgery simulation method based on CT film and its platform

Abstract

The invention discloses a three-dimensional kidney neoplasm surgery simulation method and a platform based on a computed tomography (CT) film. The method includes that firstly, a data base including object resources is built, multiple manners including CT film scanning are inputted into a CT faultage image, a sequence image is registered according to the sequence based on an outline gradient principle, a registered CT image is utilized to reconstruct segmentation tissue of an arterial phase, a venous phase and a lag phase by adopting of a three-dimensional reconstruction technology, and the segmentation tissue of the arterial phase, the venous phase and the lag phase are effectively fused in the same coordinate space. According to an imaging staging criteria and a treatment guideline of kidney neoplasm, and based on modeling results, various peration plan designing, operation stimulation, surgical risk analysis and response, and prognostic analysis are carried out, a personalized and benefit maximization treatment plan can be provided for an object, and skills and degree of proficiency of an operation can be improved, and the three-dimensional kidney neoplasm surgery simulation method can be used in medical teaching.

Description

technical field [0001] The invention belongs to the field of medical image processing and application, and in particular relates to a CT film-based three-dimensional kidney tumor operation simulation method and a platform thereof. The present invention can make full use of multiple sources of CT image data including CT film scanning, and effectively realize medical image segmentation and three-dimensional modeling of kidneys, renal tumors, renal arterial and venous structures, and collective drainage structures, with intuitive and three-dimensional display A virtual environment, and a collection of multiple simulated surgery scheme design, surgery simulation, surgical risk analysis and response, and prognosis analysis for renal tumors. Background technique [0002] The morbidity and mortality of renal tumors account for about 2% of systemic tumors, and renal cancer ranks second among malignant urological tumors in my country. The basic treatment for renal cancer is radical ...

Problems solved by technology

Furthermore, in view of the actual situation in our country, patients from other hospitals often only carry CT films made in other hospitals when they come for consultation, and it is impossible or difficult to obtain imaging data in digital format. Insufficient or missing presentations, differences in the focus of radiologists and clinicians and other factors are constrained. Usually, in order to solve this problem, re-examination with enhanced CT has to be carried out, which brings waste of medical resources and increases allergic reactions of patients. How to make full use of the existing resources of these patients and avoid repeated examinations is in line with the major policies of my country's medical reform

[0007] At present, the only research only focuses on certain aspects, mainly nephrectomy, preoperative analysis, and surgical planning simulation. For common treatments of various renal tumors, such as radical nephrectomy, laparoscopic surgery, and radiofrequency ablation Surgical planning and simulation studies of cryoablation and cryoablation are seldom involved, and there is a lack of effective methods and platforms for comprehensive analysis of comprehensive simulated surgical plans, risks, and prognosis
