AI Technical Summary
During the use of existing radiotherapy equipment, patients are unable to maintain a good posture, causing the equipment to be unable to accurately target the affected area.
A system including a radiotherapy device and a radiotherapy bed was designed. The radiotherapy bed is equipped with a bed board, a drive mechanism, a positioning mechanism, and a neck brace. The positioning mechanism achieves the fixed positioning of the patient through a thermoplastic film, a connecting rod, and a connecting mechanism. Combined with the drive mechanism and the neck brace, the patient's comfort and treatment efficiency are improved.
Through simplified operating procedures and structural design, stable and fixed positioning of patients was achieved, improving the accuracy and efficiency of radiotherapy and enhancing patient comfort.
