Abstract
A radiotherapy system, comprising: a patient support, a radiation beam generator, a gantry on which the radiation beam generator is mounted, the gantry being moveable so as to rotate the radiation beam generator around the patient support, and a control system including a real-time control system mounted on the gantry and configured to provide real-time control signals to the patient support, the radiation beam generator, and the gantry.
Claims14
A radiotherapy system, comprising:
- a patient support,
- a radiation beam generator,
- a gantry on which the radiation beam generator is mounted, the gantry being moveable so as to rotate the radiation beam generator around the patient support, and
- a control system including:
- a real-time control system mounted on the gantry and configured to provide real-time control signals to at least one of the patient support, the radiation beam generator, or the gantry to control the dynamic operational aspects of the radiation beam generator or the relative positioning of the patient support or the radiation beam generator;
- and
- an off-gantry control system mounted separately from the gantry and configured to exchange control signals with the real-time control system mounted on the gantry via a data link,
- wherein the real-time control system mounted on the gantry comprises a central controller which stores sets of instructions enabling the control system to continue to function in the event that the data link between the off-gantry control system and the real-time control system is severed;
- wherein the off-gantry control system includes a treatment planning system that is configured to provide real-time control routines for implementation by the real-time control system mounted on the gantry, and wherein the off-gantry control system is operable to transmit control instructions to the real-time control system mounted on the gantry for storage in the central controller, the central controller being configured to store instructions such that the system can continue to implement the real-time control routines in the event that the data link between the off-gantry control system and the real-time control system is severed.

- a gantry on which the radiation beam generator is mounted, the gantry being moveable so as to rotate the radiation beam generator around the patient support;
- a control system including a real-time control system mounted on the gantry and configured to provide real-time control signals to at least one of the patient support, the radiation beam generator, or the gantry;
- and
- a hardwire link that provides a data signal path between an off-gantry control system and the real-time control system mounted on the gantry, the data signal path extending through a slip ring on the gantry;
- wherein the off-gantry control system includes a treatment planning system that is configured to provide real-time control routines for implementation by the real-time control system mounted on the gantry, and wherein the off-gantry control system is operable to transmit control instructions to the real-time control system mounted on the gantry for storage in a central controller, the central controller being configured to store instructions such that the system can continue to implement the real-time control routines in the event that the hardware link between the off-gantry control system and the real-time control system is severed.
