Stereoscopic intersection damage mesh establishment method and focus damage system

Abstract

The embodiment relates to a stereoscopic intersection damage mesh establishment method and a focus damage system. The establishment method includes the steps: determining nodes of a stereoscopic intersection damage mesh as contact points of electrodes; determining edges of the stereoscopic intersection damage mesh, wherein the distance between the contact points of two electrodes corresponding to the edges is less than or equal to the damage distance; and establishing the stereoscopic intersection damage mesh based on the nodes and edges. According to the embodiment of the invention, a dipole electric field can be formed between the contact points of the two electrodes corresponding to each edge in the established stereoscopic cross damage mesh, and then a damage focus can be formed; moreover, the distance between the contact points of the two electrodes corresponding to the edges is less than or equal to the damage distance, so the damage focus is a continuous damage focus, and the established stereoscopic cross damage mesh enlarges the damage scope of the damage focus, and the stereoscopic focus can be completely covered.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of lesion damage, and in particular to a method for establishing a three-dimensional intersection damage grid, a lesion damage system, and a non-transitory computer-readable storage medium. Background technique [0002] Traditional stereotactic radiofrequency thermocoagulation has been widely criticized due to its small damage range, and it has not become an internationally recognized first-line treatment at present. Currently, the best approach to a focal, distant epileptogenic focus is to remove it. One of the clearing methods is stereotactic radiofrequency thermocoagulation (Radio Frequency thermocoagulation, RF-TC), which is to inactivate the cranium by generating heat through a bipolar electric field located in the cranium, usually at a temperature of 75-80°C. within the lesion tissue. Introduced in 1947, this method has been used in epilepsy patients for a long time. Howeve...

Problems solved by technology

However, RF-TC still stays in a lower spatial dimension (one-dimensional) all over the world at present, and the range of damage produced is relatively sporadic, which is not enough to completely cover the naturally formed epileptogenic focus

Moreover, egg white is not homogeneous and contains many layers of different densities, which is not enough to fully infer the detailed parameters of RF-TC
