Mechanical treatment chair and its control system

Technical field

The present invention relates to a chair, and more particularly to a mechanical treatment chair.

Background technique

Due to its superior radiophysical and radiobiological properties, proton heavy ion radiotherapy has a greater advantage than conventional photon radiotherapy. Proton heavy ions have a "Prague peak" energy release trajectory throughout the range, which can be used for tumors. The cells are accurately killed, and the damage to surrounding normal tissues is significantly reduced, but there is a high precision requirement for tumor localization. The existing proton heavy ion therapy uses a treatment bed, which is not suitable for the treatment of head and neck cancer. Traditional mechanical treatment chairs are usually only used as tools for carrying patients, lacking positioning functions, and can not meet the needs of precision radiotherapy.
