Abstract
A method for preventing an emission head or arm assembly from entering an exclusion zone. The method may include calculating a variable dimension exclusion zone of a radiosurgery system, and preventing at least one of the emission head or arm assembly from entering the variable dimension exclusion zone. The method may also include establishing a exclusion zone of a radiosurgery system, the radiosurgery system comprising an x-ray source having an emission head, moving the emission head during treatment of a patient, wherein the exclusion zone travels with the emission head, and detecting a presence and location of an object in the traveling exclusion zone.
Claims28
A method, comprising:
- calculating a variable dimension exclusion zone of a radiosurgery system, the radiosurgery system comprising an x-ray source having an emission head and an arm assembly;
- and
- preventing at least one of the emission head or arm assembly from entering the variable dimension exclusion zone.
A method, comprising:
- establishing a exclusion zone of a radiosurgery system, the radiosurgery system comprising an x-ray source having an emission head;
- moving the emission head during treatment of a patient, wherein the exclusion zone travels with the emission head;
- and
- detecting a presence and location of an object in the traveling exclusion zone.
An apparatus, comprising:
- a radiosurgery system comprising an x-ray source having an emission head and an arm assembly;
- and
- a controller coupled to the radiosurgery system, the controller to calculate a variable dimension exclusion zone of a radiosurgery system, wherein the controller is configured to prevent at least one of the emission head or arm assembly from entering the variable dimension exclusion zone.
An apparatus, comprising:
- a radiosurgery system comprising an x-ray source having an emission head and an arm assembly;
- and
- means for calculating a variable dimension exclusion zone of a radiosurgery system.
An apparatus, comprising:
- means for establishing a exclusion zone of a radiosurgery system, the radiosurgery system comprising an x-ray source having an emission head;
- means for moving the emission head during treatment of a patient, wherein the exclusion zone travels with the emission head;
- and
- means for detecting a presence and location of an object in the traveling exclusion zone.
