System and method for radiotherapy field delivery time optimization

An electronic system for radiotherapy treatment planning, the system comprising:

• a display device;
• a memory coupled to the display device;
• and
• a processor in communication with the memory, wherein the processor is operable to execute instructions for performing a method of radiotherapy treatment planning, the method comprising:
• accessing a radiotherapy treatment plan comprising a plurality of treatment layers, each treatment layer of the plurality of treatment players comprising a plurality of spots;
• assigning a weight for a treatment time objective of the radiotherapy treatment plan using input received from a graphical user interface rendered on the display device;
• modifying a spot from a treatment layer of the plurality of treatment layers based on the weight and a cost of the spot to produce a modified treatment layer;
• and
• generating a modified radiotherapy treatment plan using the modified treatment layer, wherein the modified radiotherapy treatment plan is operable to be executed by a delivery machine to apply radio therapy treatment to a target in accordance with the modified radiotherapy treatment plan.

A non-transitory computer-readable storage medium embodying instructions that, when executed by a processor, causes the processor to perform a method of radiotherapy treatment planning, the method comprising:

• accessing a radiotherapy treatment plan comprising a plurality of treatment layers, each treatment layer of the plurality of treatment layers comprising a plurality of spots;
• assigning a weight for a treatment time objective of the radiotherapy treatment plan based on received inputs;
• modifying a spot from a treatment layer of the plurality of treatment layers based on the weight and a cost of the spot to produce a modified layer;
• and
• generating a modified radiotherapy treatment plan using the modified treatment layer, wherein the modified radiotherapy treatment plan is operable to be executed by a delivery machine to apply radiotherapy treatment to a target in accordance with the modified treatment plan.
