Radiation control and minimization system and method using collimation/filtering

摘要

A radiation control system and method are provided in which radiation delivered to a patient and/or the operator of the equipment is minimized. The radiation control system may be used in a large variety of applications including applications in which radiation source is used to inspect an object, such as, for example, medical imaging, diagnosis and therapy, in manufacturing operation using radiation, in airports scanning systems, in different security setups, and in nuclear reactors automation and process control. The radiation control system and method may also be used with 3D imaging.

1. A radiation device, comprising:
a radiation source that generates a radiation beam that is directable towards a subject; a radiation controller connected to the radiation source, the radiation controller having a fixation zone module that determines a fixation zone of an operator of the radiation source and the radiation controller generates a collimator control signal based in part on the determined fixation zone of the operator; and a collimator, connected to the radiation controller, 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 for radiation that is outside of the region of interest.
