Microwave ablation system

Abstract

A microwave ablation system includes a target management module, a needle passage management module, a thermal field calculation module, and an ablation parameter calculation module. The target area management module generates a three-dimensional model according to tumor image data, the needle passage management module can perform addition, deletion, modification and check operations on ablation parameters, the thermal field calculation module performs thermal field simulation according to the ablation parameters, and the ablation parameter calculation module calculates the ablation parametersaccording to the target area three-dimensional model and a simulation thermal field. The invention can provide an ablation scheme which is based on tumor conformity and can meet the requirements of different needle distribution numbers and needle distribution modes. The invention further provides a visualization module and an interaction module, so the man-machine interaction is facilitated, andthe ablation safety is guaranteed through visualization.

Description

technical field [0001] The invention relates to the field of microwave ablation, in particular to a microwave ablation system. Background technique [0002] Puncture path planning in microwave ablation is a key step to ensure efficient and safe treatment planning. In clinical practice, two or more ablation needles are often used to ablate large tumors simultaneously or sequentially. For the purpose of controlling the ablation range and estimating the ablation effect, clinicians often have requirements for the spatial positions of these ablation needles. In terms of ablation needles, they are required to arrange ablation needles according to certain rules. [0003] The existing ablation system mainly adopts two points, that is, parallel needle placement and conformal ablation. For large tumors, the method of arranging multiple parallel needles is used to expand the ablation range, and then the ablation ranges are combined to ensure conformal ablation. However, according to...

Problems solved by technology

However, according to these two rules, there are still countless ways of needle placement, making it difficult to make a plan, complicated to operate, and unsatisfactory in the implementation of the plan.

[0004] At present, doctors have different habits of needle placement when making surgical plans, resulting in vastly different surgical difficulties and therapeutic effects. At the same time, doctors cannot accurately predict the distance between parallel needles and needle withdrawal to control the range of the formed thermal field.
