Radiotherapy treatment planning based on treatment delivery efficiency

A non-transitory computer-readable storage medium that includes a set of instructions which, in response to execution by a processor of a computer system, cause the processor to perform a method of radiotherapy treatment planning based on treatment delivery efficiency, wherein the method comprises:

• configuring at least one dosimetric planning objective for a subject requiring radiotherapy treatment;
• configuring at least one non-dosimetric planning objective based on a parameter for operation of a radiotherapy treatment delivery system, wherein the parameter affects efficiency of treatment delivery by the radiotherapy treatment delivery system to the subject;
• generating a set of multiple treatment plan variants based on the at least one dosimetric planning objective and the at least one non-dosimetric planning objective;
• identifying, from the set of multiple treatment plan variants, a first treatment plan associated with a first tradeoff among the at least one dosimetric planning objective and the at least one non-dosimetric planning objective;
• and
• identifying, from the set of multiple treatment plan variants, a second treatment plan associated with a second tradeoff that varies from the first tradeoff, wherein the second treatment plan is associated with improved efficiency of treatment delivery compared to the first treatment plan.

A computer system, comprising a processor and a non-transitory computer-readable medium having stored thereon instructions that, when executed by the processor, cause the processor to:

• configure at least one dosimetric planning objective for a subject requiring radiotherapy treatment;
• configure at least one non-dosimetric planning objective based on a parameter for operation of a radiotherapy treatment delivery system, wherein the parameter affects efficiency of treatment delivery by the radiotherapy treatment delivery system to the subject;
