胶质瘤治疗系统
By using alternating electric field therapy in the glioma treatment system, AC signals are applied alternately through two pairs of insulated electrodes, solving the problem of large side effects in existing tumor treatment methods, achieving effective inhibition of gliomas, and reducing damage to normal cells.

AI Technical Summary
Existing cancer treatments such as surgery, radiotherapy, and chemotherapy have side effects, and electric field therapy is not effective enough in inhibiting tumor cell proliferation, especially for gliomas, where the treatment effect needs to be improved.
A glioma treatment system is employed, which uses two pairs of insulated electrodes to alternately apply periodic control signals to drive AC signals, forming an alternating electric field with perpendicularly intersecting directions. The AC signals switch between segmented voltage increases and slow decreases at different time periods, with a frequency of 200kHz and an electric field strength of 1V/cm. The time periods T1 and T2 are both 400ms-980ms, thus achieving the alternating switching of the electric field.
It effectively inhibits tumor cell proliferation, reduces damage to normal cells, and improves the effectiveness of tumor treatment, especially for gliomas.
