Lesion focus generation method and lesion focus damage system

Abstract

The embodiment of the invention relates to a lesion focus generation method and a lesion focus damage system. The damage focus generation method comprises the steps that a three-dimensional cross damage grid covering a focus is established, the three-dimensional cross damage grid comprises a plurality of nodes and a plurality of edges, the nodes are contacts of electrodes, and the distance between the contacts of the two electrodes corresponding to the edges is smaller than or equal to the damage distance; and power supply control on the electrode is carried out to generate a damage focus of the focus. In the embodiment of the invention, in the established three-dimensional cross damage grid, a dipole electric field can be formed between electric shocks of two electrodes corresponding to each edge, and then a damage focus is formed; and the distance between the contact points of the two electrodes corresponding to the edges is smaller than or equal to the damage distance, so that the damage focus is a continuous damage focus, the damage range of the damage focus is enlarged through the established three-dimensional cross damage grids, and the three-dimensional focus can be completely covered.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of lesion damage, and in particular to a lesion damage generation method, 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. However, conventional RF-TC methods cannot simu...

AI Technical Summary

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
