Abstract
A control circuit accesses at least one objective function to be optimized pursuant to radiation treatment planning via an iterative optimization process comprising a plurality of iteration rounds where, in at least some of the iteration rounds, the control circuit employs a neural network that outputs at least one corresponding fluence map before ultimately outputting an optimized radiation treatment plan.
Claims21
A method for optimizing a radiation treatment plan for a particular patient using a particular radiation treatment apparatus, the radiation treatment plan comprising a control point sequence, the method comprising:
- by a control circuit:
- accessing at least one objective function to be optimized via an iterative optimization process comprising a plurality of iteration rounds;
- in at least some of the iteration rounds, employing a neural network that outputs at least one corresponding fluence map;
- outputting an optimized radiation treatment plan.
An apparatus for optimizing a radiation treatment plan for a particular patient using a particular radiation treatment apparatus, the radiation treatment plan comprising a control point sequence, the apparatus comprising:
- a control circuit configured to:
- access at least one objective function to be optimized via an iterative optimization process comprising a plurality of iteration rounds;
- in at least some of the iteration rounds, employ a neural network that outputs at least one corresponding fluence map;
