A lesion virtual puncture system based on image information fusion

Abstract

The invention relates to the technical field of medical assistance, in particular to a focus virtual puncture system based on image information fusion. The focus virtual puncture system comprises an image acquisition module, an image fusion module, a terminal point positioning module, a route generation module and a weight analysis module. Overall image data are obtained through processing of the image acquisition module and the image fusion module, the position relations between all parts in an image are determined, the focus image data are analyzed through the terminal point positioning module, the central point of the focus image data is determined, the route generation module connects all pixel points in body surface image data with the central point of the focus image data and generates a virtual route set, and the weight analysis module obtains weight values of all virtual routes according to analysis on the position relations between all the virtual routes and in-vivo image data. By means of the focus virtual puncture system, data of all the virtual routes under the parameter condition are obtained; important reference information is provided for doctors so that doctors can easily and rapidly plan the optimal virtual route in a three-dimensional image; the focus virtual puncture system does not rely on subjective experience of doctors and has a good medical assistance effect.

Description

technical field [0001] The invention relates to the field of medical assistance technology, in particular to a lesion virtual puncture system based on image information fusion. Background technique [0002] The analysis of medical images is an emerging medical analysis method with a wide range of applications. In radiofrequency ablation surgery, the design and implementation of the puncture needle path need to avoid the abdominal bones and blood vessels to avoid serious collision damage to the human body. Therefore, various requirements must be met during the path planning process, including the shortest route, avoiding Vascular and skeletal disorders, minimum trauma and best therapeutic effect, etc. [0003] In the patent document of Chinese Patent Publication No.: CN 103479430A, it proposes a planning method in which a doctor designs a virtual path based on preoperative analysis. In the technical solution of this patent, the doctor manually plans possible virtual paths a...

Problems solved by technology

This solution relies too much on the subjective judgment of the doctor, or can only obtain some possible virtual paths, and does not achieve the planning effect of the optimal virtual path, and cannot achieve the required puncture purpose of minimum trauma and best curative effect
