Abstract
The present disclosure provides systems and methods for adjusting a multi-leaf collimator (MLC) in a treatment process according to a treatment plan or a portion thereof. The MLC may include at least one closed leaf pair in the treatment process. The method may include: for each of the at least one closed leaf pair, determining an offset for the closed leaf pair; and causing the at least one closed leaf pair to move based on the determined at least one offset before or during the treatment process.
Claims20
A method implemented on at least one machine each of which has at least one processor and at least one storage device for adjusting a multi-leaf collimator (MLC) in a treatment process according to a treatment plan or a portion thereof, the MLC including at least one closed leaf pair in the treatment process, the method comprising:
- for each of the at least one closed leaf pair, determining an offset for the closed leaf pair;
- and
- causing the at least one closed leaf pair to move based on the determined at least one offset before or during the treatment process.
A system for adjusting a multi-leaf collimator (MLC) in a treatment process according to a treatment plan or a portion thereof, the MLC including at least one closed leaf pair in the treatment process, the system comprising:
- a drive mechanism configured to drive the at least one closed leaf pair to move;
- and
- a controller configured to:
- for each of the at least one closed leaf pair, determining an offset for the closed leaf pair;
- and
- causing the at least one closed leaf pair to move based on the determined at least one offset before or during the treatment process.
A system for adjusting a multi-leaf collimator (MLC) in a treatment process according to a treatment plan or a portion thereof, the MLC including at least one closed leaf pair in the treatment process, the system comprising:
- at least one storage device storing a set of instructions;
- and
- at least one processor in communication with the storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to perform operations including:
- for each of the at least one closed leaf pair, determining an offset for the closed leaf pair;
- and
- causing the at least one closed leaf pair to move based on the determined at least one offset before or during the treatment process.
