executing at least a part of a second package of the treatment plan to deliver additional radiation towards the patient;
automatically stopping a delivery of radiation during execution of the first or the second package in response to a breathing of the patient not meeting a criterion,
wherein the act of stopping the delivery of radiation results in non-delivered radiation for the first or the second package; and
delivering radiation to make up at least a part of the non-delivered radiation.
2. The method of claim 1 , wherein the act of stopping the delivery of radiation places the first package or the second package in a hold state for a prescribed duration.
3. The method of claim 2 , further comprising determining if a breathing of the patient meets the criterion during the hold state.
4. The method of claim 3 , further comprising lifting the hold state if the breathing meets the criterion, wherein the radiation is delivered to make up the at least a part of the non-delivered radiation in response to the hold state being lifted.
5. The method of claim 3 , further comprising executing a third package of the treatment plan to deliver additional radiation towards the patient if the breathing does not meet the criterion by an end of the hold state, wherein the act of delivering radiation to make up the at least a part of the non-delivered radiation is performed after the third package is executed.
6. The method of claim 3 , further comprising selecting the third package from a plurality of packages before the third package is executed.
7. The method of claim 6 , wherein the third package is selected based on requirements of remaining packages that need to be delivered.
8. The method of claim 6 , wherein the third package is selected based on the third package having a delivery requirement that is a closest to that of a current system configuration.
9. The method of claim 8 , wherein the delivery requirement comprises one or both of a prescribed source position and prescribed leaves' positions.
10. The method of claim 1 , further comprising providing a user interface for prescribing at least a part of the treatment plan that includes the first package and the transition, the user interface comprising a screen displaying graphics for allowing a user to input information, wherein the graphics are generated using a processing unit;
wherein the graphics include a first package input area for allowing the user to define the first package that prescribes one or more parameters for delivering radiation; and
wherein the graphics include a first transition input area for allowing the user to define the transition that prescribes one or more parameters for operating one or more components of the treatment system to change the configuration of the treatment system while radiation is not being delivered.
11. A radiation system for delivering radiation in a session, comprising:
a processing unit configured to
execute at least a part of a first package of a treatment plan to deliver radiation towards a patient based at least in part on a physiological phase or a position of the patient,
execute a transition of the treatment plan for changing a configuration of the radiation system when no radiation is being delivered by the radiation system,
execute at least a part of a second package of the treatment plan for delivering additional radiation towards the patient,
automatically stop a delivery of radiation during execution of the first package or the second package in response to a breathing of the patient not meeting a criterion, wherein the act of stopping the delivery of radiation results in non-delivered radiation for the first package or the second package, and
operate one or more components of the radiation system radiation to deliver radiation to make up at least a part of the non-delivered radiation.
12. The system of claim 11 , wherein the processing unit is configured to stop the delivery of radiation to place the first package or the second package in a hold state for a prescribed duration.
13. The system of claim 12 , wherein the processing unit is configured to determine if a breathing of the patient meets the criterion during the hold state.
14. The system of claim 13 , wherein the processing unit is configured to lift the hold state if the breathing meets the criterion, and wherein the processing unit is configured to operate the one or more components of the radiation system to deliver the radiation to make up the at least a part of the non-delivered radiation in response to the hold state being lifted.
15. The system of claim 13 , wherein the processing unit is configured to execute a third package of the treatment plan for delivering additional radiation towards the patient if the breathing does not meet the criterion by an end of the hold state, wherein the processing unit is configured to operate the one or more components of the radiation system to deliver the radiation to make up the at least a part of the non-delivered radiation after the third package is executed.
16. The system of claim 13 , wherein the processing unit is configured to select the third package from a plurality of packages before the third package is executed.
17. The system of claim 16 , wherein the processing unit is configured to select the third package based on requirements of remaining packages that need to be delivered.
18. The system of claim 16 , wherein the processing unit is configured to select the third package based on the third package having a delivery requirement that is a closest to that of a current system configuration.
19. The system of claim 18 , wherein the delivery requirement comprises one or both of a prescribed source position and prescribed leaves' positions.
