Abstract
A method for use in a treatment planning process or in a treatment process includes determining a type of critical organ for healthy tissue, and accumulating dose for the healthy tissue based on the type of critical organ. A method for use in a treatment planning process or in a treatment process includes determining a type of critical organ for healthy tissue, and determining a constraint for the healthy tissue, wherein the constraint is determined based on different movement trajectories and the type of critical organ.
Claims48
A method for use in a treatment planning process or in a treatment process, comprising:
- determining a type of critical organ for healthy tissue;
- and
- determining a dose for the healthy tissue based on the type of critical organ;
- wherein the dose is an average accumulated dose if the type of critical organ is parallel, and the dose is a maximum accumulated dose if the type of critical organ is serial.
A system for use in a treatment planning process or in a treatment process, comprising a processor configured for:
- determining a type of critical organ for healthy tissue;
- and
- determining a dose for the healthy tissue based on the type of critical organ;
- wherein the processor is configured to determine an average accumulated dose as the dose if the type of critical organ is parallel, and determine a maximum accumulated dose as the dose if the type of critical organ is serial.
A method for use in a treatment planning process or in a treatment process, comprising:
- determining a type of critical organ for healthy tissue;
- and
- determining a constraint for the healthy tissue based on different movement trajectories and the type of critical organ;
- wherein if the determined type is parallel, then the constraint comprises an average dose constraint, and if the determined type is serial, then the constraint comprises a maximum dose constraint.
A system for use in a treatment planning process or in a treatment process, comprising:
- a processor configured for receiving information regarding a type of critical organ for healthy tissue;
- wherein the processor is also configured for determining a constraint for the healthy tissue by based on different movement trajectories and the type of critical organ;
- and
- wherein the processor is configured to use an average dose constraint as the constrain if the type of critical organ is parallel, and a maximum dose constraint as the constraint if the type of critical organ is serial.
