From；
S6, pass through patient body position's photo captured by the second optical camera below accelerator head and pendulum position reference picture pair
Than after confirmation pendulum position is errorless, radiotherapy technology person or doctor leave therapeutic room, close therapeutic room's protective door, operate radiotherapy accelerator
Control computer starts this radiation exposure, carries out radiotherapy；
In S7, Patients During Radiotherapy, sound broadcasting device is breathed according to rhythm rule prompt patient, is brought with reducing respiratory movement
Radiotherapy error；
S8, patient is monitored in real time by the second optical camera below accelerator head, when patient's unintentional motion causes to regard
When the difference value of frequency image and pendulum position reference picture is greater than the set value, control system stops radiotherapy operation, radiotherapy technology person or doctor
It is raw patient is put again position it is errorless after, restore this treatment.
