Abstract
Disclosed herein is a method of positioning a patient for radio-therapy treatment using a radiotherapy device. The method comprises determining an identity of a treatment beam that is to be used to treat the patient, determining an offset between a reference location and an isocentre location for the identified treatment beam that is to be used to treat the patient, and changing a spatial relationship between the patient and at least a part of the radiotherapy device, according to the determined offset.
Claims19
A method of positioning a patient for radiotherapy treatment using a radiotherapy device, the method comprising:
- determining an identity of a first treatment beam that is to be used to treat the patient;
- determining an offset between a reference location and an isocentre location for the determined first treatment beam that is to be used to treat the patient, wherein the reference location comprises a location of an isocentre of a second treatment beam that has an identity that is different to the identity of the first treatment beam that is to be used to treat the patient;
- and
- changing a spatial relationship between the patient and at least a part of the radiotherapy device, according to the determined offset.
A method of determining a positioning for a patient for radiotherapy treatment using a radiotherapy device, the method comprising:
- determining an identity of a first treatment beam that is to be used to treat the patient;
- determining an offset between a reference location and an isocentre location for the determined first treatment beam that is to be used to treat the patient, wherein the reference location comprises a location of an isocentre of a second treatment beam that has an identity that is different to the identity of the first treatment beam that is to be used to treat the patient;
- and
- determining a change in spatial relationship, between the patient and at least a part of the radiotherapy device, according to the determined offset.
A radiotherapy system comprising:
- a radiotherapy device comprising a treatment apparatus for providing a radiotherapy treatment beam;
- a patient positioning surface;
- and
- a controller configured to:
- determine an identity of a first treatment beam that is to be used to treat the patient;
- determine an offset between a reference location and an isocentre location for the determined first treatment beam that is to be used to treat the patient, wherein the reference location comprises a location of an isocentre of a second treatment beam that has an identity that is different to the identity of the first treatment beam that is to be used to treat the patient;
- and
- change a spatial relationship between the patient and at least a part of the radiotherapy device, according to the determined offset.
A non-transitory computer readable storage medium comprising computer-executable instructions which, when executed by a processor of a computer, cause the computer to:
- determine an identity of a first treatment beam that is to be used to treat a patient;
- determine an offset between a reference location and an isocentre location for the determined first treatment beam that is to be used to treat the patient, wherein the reference location comprises a location of an isocentre of a second treatment beam that has an identity that is different to the identity of the first treatment beam that is to be used to treat the patient;
- and
- change a spatial relationship between the patient and at least a part of a radiotherapy device, according to the determined offset.
