Abstract
A method of radiotherapy treatment planning is described. A planned target volume is identified for radiotherapy treatment and at least one volume of interest is identified. The mass, density, and total deposited energy contained in the planned target volume and the volumes of interest are identified and dose objectives are determined. At least one of the objectives is a function of the identified mass, density, or deposited energy. A composite objective function is determined using the dose objectives for the planned target volume and the volumes of interest. A near optimal solution to the composite objective function is determined to produce a radiotherapy treatment plan.
