Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a phased array antenna, a microwave hyperthermia device and a device control method. Background technique [0002] Microwave hyperthermia refers to the use of microwave thermal effect to heat up biological tissue to kill tumor cells. Microwave hyperthermia has been used in clinical treatment as a synergistic therapy of radiotherapy and chemotherapy. Extracorporeal hyperthermia is a microwave hyperthermia method in which the microwave hyperthermia antenna is used outside the human body to focus electromagnetic waves on the target area for treatment, in order to reduce the damage to the patient's body tissue. [0003] However, the electric field superposition efficiency of the existing antenna is low, and there is side lobe interference, which cannot obtain good near-field focusing characteristics, and the microwave focusing effect is not good, resulting in poor treatm...
