Novalis+Imotion is an integrated radiotherapy and operation equipment. Its rotating C-type structure can be used for radiotherapy in almost any part of the patient’s body. During the whole process, the design is wholly integrated into the development of mechanical automation, and we design a series of processes of operating environment and radiotherapy, do some research and evaluation on the usability of medical devices so that we ensure the maximum release of patients’ physiological and psychological pressure.
