Embodiment Construction

[0024] The present invention will be described in further detail in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, the present invention provides a CT image-guided thermal ablation needle positioning and navigation system for liver tumors. The hardware components of the system include: a navigation workstation, an intraoperative positioning device, and an image display device.

[0026] The navigation workstation is mainly used to process CT scan images, surgical planning, and navigation data. Specifically, it includes storing and processing a large amount of image data, segmenting and reconstructing the liver and lesions in the CT volume data, and quickly visualizing, and planning preoperative surgery based on the 3D visualization model (setting target points and puncture paths, etc.), and integrating the 3D reconstruction The visualization model and the real-time spatial positioning information of the thermal ablation needle ...

Abstract

The invention relates to a CT image-guided liver tumor thermal ablation needle location and navigation system, which comprises a hardware constituting part and a software constituting part, wherein the hardware constituting part comprises a navigation workstation, an intra-operative location device and image display equipment. The software constituting part comprises an image data management module, a 3D visualization module, a 3D image automatic division module, a preoperative operation planning module, an intra-operative navigation module and a post-operative therapeutic effect evaluation module. The CT image-guided liver tumor thermal ablation needle location and navigation system disclosed by the invention can implement computer assisted therapy from various aspects, including 3D visualization and spatial location on liver tumor and neighboring structures, preoperative operation planning, real-time spatial location and navigation on a thermal ablation needle and post-operative therapeutic effect evaluation. The location and navigation system disclosed by the invention can shorten a time of thermal ablation therapy and reduce the occurrence rate of complications, so that the safety and the effectiveness of the liver tumor thermal ablation therapy are enhanced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a CT image-guided thermal ablation needle positioning and navigation system for liver tumors Background technique [0002] Primary liver cancer is one of the most common malignant tumors in the world, with high morbidity and mortality. At present, radiofrequency ablation and microwave ablation have been widely used in the clinical treatment of liver tumors, especially for patients with liver tumors who are not suitable for surgical resection, percutaneous (microwave / radiofrequency) thermal ablation of tumors has become a commonly used minimally invasive treatment in clinic . Computed Tomography (CT) imaging technology is widely used in the diagnosis and treatment of liver cancer due to its advantages of accurate anatomical information, high resolution, short scanning time and high penetration rate. [0003] Currently, CT-guided tumor thermal ablation therapy is clinically used. B...
