摘要：
A radiation minimisation method is disclosed and a radiation device, comprising a radiation source (26) that generates a radiation beam that is directable towards a subject (20)； a radiation controller (46) connected to the radiation source (24), the radiation controller (46) having a fixation zone module (42) that determines a fixation zone of an operator of the radiation source (24) and the radiation controller (46) generates a collimator control signal based in part on the determined fixation zone of the operator； and a collimator (461), connected to the radiation controller (46), that based on the collimator control signal, continually filters the radiation that is outside of a region of interest to reduce a radiation dose from the radiation source (24) for radiation that is outside of the region of interest.
