Description

Technical Field

[0001] The invention relates to the field of tumor treatment electric field measurement, and in particular to a system for clearly displaying a double-layer filament test image. Background Art

[0002] Tumor treating fields are delivered through a portable, non-invasive medical device that uses a low-intensity, medium-frequency (usually 200kHz) alternating electric field to act on the tubulin of proliferating cancer cells. This electric field can interfere with the mitotic process of tumor cells, causing apoptosis of affected cancer cells and inhibiting tumor growth.

[0003] Although tumor treatment electric fields have become the fourth way to treat tumors, at present, when conducting tumor treatment electric fields, only simulation research is used to analyze the electric field distribution inside the brain, and there is no actual measurement method to directly measure the electric field value. Therefore, a direct measurement method to measure the electric field of the tumor during tumor treatment electric fields is very important.

[0004] To this end, the present invention proposes a system for clearly displaying a double-layer filament test image. Summary of the invention
