Patients on radiation treatment of the head and neck require an uncomfortable device to limit patient movement to 3mm. We propose a novel cyber-physical system approach with a vision-infrared based motorized positioning system (VIMPS) and soft robotic fingers to both monitor and correct the position of a patient’s head. The proposed system aims to constantly detect the patient’s head position and any movement in real-time while the patient is undergoing radiotherapy. If any positional change greater than 2mm is detected, this system will trigger a pre-set action, such as halting the treatment, thereby allowing corrections to be made before treatment is resumed. The threshold of 2mm is chosen to match existing treatment standards. With a secure network connection and robust control between the VIMPS system, soft robotic manipulators and radiation device, we could realize accurate radiation doses distribution.
