Abstract
A method for determining a monitor unit that is associated with a process using ions, includes obtaining a depth dose curve, determining a characteristic parameter based on the depth dose curve, and using the characteristic parameter to determine a first monitor unit factor. A system for determining a monitor unit that is associated with a process using protons, includes a processor that is configured for obtaining a depth dose curve, determining a characteristic parameter based on the depth dose curve, and using the characteristic parameter to determine a first monitor unit factor.
Claims38
A method for determining a monitor unit that is associated with a process using ions, comprising:
- obtaining a depth dose curve;
- determining a characteristic parameter based on the depth dose curve;
- using the characteristic parameter to determine a first monitor unit factor for a first layer that is associated with a first feature of a range modulator;
- and
- storing the first monitor unit factor in a device having a non-transitory medium;
- wherein the act of using the characteristic parameter to determine the first monitor unit factor is performed by a processor.
A system for determining a monitor unit that is associated with a process using ions, the system comprising a processor, wherein the processor is configured for:
- obtaining a depth dose curve;
- determining a characteristic parameter based on the depth dose curve;
- and
- using the characteristic parameter to determine a first monitor unit factor for a first layer that is associated with a first feature of a range modulator.
A computer product having a set of instructions stored in a non-transitory medium, an execution of which causes a process to be performed, wherein the process is for determining a monitor unit that is associated with a process using ions, the process comprising:
- obtaining a depth dose curve;
- determining a characteristic parameter based on the depth dose curve;
- and
- using the characteristic parameter to determine a first monitor unit factor for a first layer that is associated with a first feature of a range modulator.
