Method and apparatus to detect and respond to radiation treatment plan spot weight edits
A radiation treatment plan for a particular patient is optimized that provides corresponding resultant radiation dosing information. Such optimization can include, by one approach, calculating a corresponding influence matrix. Upon detecting at least one manual edit to at least one spot weight that corresponds to the radiation treatment plan, these teachings can provide for responsively generating new radiation dosing information in at least near real-time as a function of a corresponding influence matrix.
