Abstract
A radiation treatment apparatus ( ) includes a diagnostic imaging scanner ( ) that acquires a diagnostic image of a subject. A contouring processor ( ) computes a radiation treatment objective based thereon. A radiation delivery apparatus ( ) delivers radiation to the subject. An inverse planning processor ( ) computes radiation beamlet parameters conforming with the radiation treatment objective by: grouping the beamlet parameters; assigning a weight to each group ( ); optimizing a first group ( ) to produce an intermediate dosage objective corresponding to the treatment objective weighted by a weight of the first group ( ); and optimizing successive groups ( ) to produce with the previously optimized groups ( ) an increasing intermediate dosage objective corresponding to the treatment objective weighted by the combined weights of the previous and current groups ( ). A conversion processor ( ) converts the optimized beamlet parameters into configuration parameters of the radiation delivery apparatus ( ).
