Radiotherapy devices and access authorisation

A computer-implemented method of determining whether a radiotherapy device configured to provide therapeutic radiation to a patient should be authorized for use;

• the device comprising one or more components, each component of the one or more components being coupled with at least one identifier configured to provide data identifying the component it is coupled with;
• the method comprising:
• receiving, from the at least one identifier, data identifying each of the one or more plurality of components of the radiotherapy device;
• sending the identifying data to a central processor to determine whether at least one authorization criterion is met based on the identifying data and authorization data;
• and
• receiving an indication which indicates whether the radiotherapy device is authorized for use.

A radiotherapy device configured to provide therapeutic radiation to a patient, the device comprising one or more components, each component of the one or more components being coupled with at least one identifier, wherein the at least one identifier provides data identifying a particular component that the at least one identifier coupled with;

• and
• a device processor coupled to a device memory storing computer executable instructions which, when executed by the device processor, cause the device processor to perform operations comprising:
• receiving, from the at least one identifier, data identifying each component of the one or more components of the radiotherapy device;
• determining whether at least one authorization criterion is met based on the identifying data and authorization data;
• and
• responsive to determining that the at least one authorization criterion is met, determining that the radiotherapy device is authorized for use.
