Microwave ablation simulation system

Abstract

The invention provides a microwave ablation simulation system. The types of ablation needles are received by virtue of a simulation computing module, and after configuring corresponding parameters to the types of the ablation needles in accordance with parameters of the different types of the ablation needles, an optimum scheme is computed out in accordance with a received 3D model of tumor and surrounding environment thereof as well as the corresponding parameters of the types of the ablation needles, so that the problem that normal tissues of a patient can get injured easily in the case that an ablation range is too large or tumor residue can be caused when the ablation range is too small; and then, the optimum ablation scheme, as tumor ablation simulation scheme information is outputted, so that an optimum multi-needle arranging microwave ablation scheme is offered to relatively large tumors.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a microwave ablation simulation system. Background technique [0002] Microwave ablation refers to the use of electromagnetic waves with a frequency >30MHz to puncture into the lesion tissue area through the microwave treatment pole (microwave antenna) under the guidance of images. During microwave ablation, the rotation of dipole molecules is used to generate heat, and the friction between ions generates heat. , so that the temperature of the tissue in the ablation zone reaches a temperature of about 100 degrees Celsius, resulting in coagulation necrosis of the ablation tissue. Microwave ablation technology has the advantages of high thermal efficiency, fast heating speed, uniform thermal field, etc., and is less affected by the heat sinking effect of blood vessels. It is often used for surgical treatment of human tumors. [0003] The shape of human tumors is generally irr...

AI Technical Summary

Problems solved by technology

In theory, if a 7cm-diameter tumor is treated with a 4cm-diameter spherical lesion, 22 points are required to completely cover it, and a 5cm-diameter spherical lesion also requires 12 points, which is very difficult in practice

[0004] The multi-point ablation scheme in the prior art lacks effective technical support means and relies entirely on the experience of clinicians to formulate

However, in clinical practice, it is difficult to formulate the best plan for multi-needle needle ablation. To completely ablate the tumor, the ablation range is often too large, which will damage the patient's normal tissue, and too small will cause tumor residues.
