Abstract:
1. A method of radiation planning comprising the steps of: (a) obtaining an image of a patient encompassing tumorous and non-tumorous tissue; (b) applying an encompassing field to the image having an area covering the tumorous and non-tumorous tissue; (c) using a graphical user interface to subtract subset fields corresponding to radiation sensitive non-tumorous tissues from the encompassing field to define a treatment area; and (d) inputting the treatment area to a computer program to generate a radiation treatment plan controlling radiation placement and intensity based on at least one prescribed dose to the treatment area, wherein the encompassing field is a pattern from a library of encompassing fields for different procedures and wherein the step of applying the encompassing field fits one encompassing field from the library to the patient image based on anatomical image landmarks.
