Abstract
The present invention concerns a radiation inverse treatment planning system for a linear accelerator. The system includes a radiation source, configured for delivering individual radiotherapeutic dose shots (aj), each individual radiotherapeutic dose shot having a predetermined location and incidence angle inside and/or outside a target area, a size and a shape. The system also includes at least a data bus system (102), and a memory (106) coupled to the data bus system (102), wherein the memory (106) includes a computer usable program code. The system also includes a processing unit (104) coupled to the data bus system (102), wherein the processing unit (104) is configured to execute the computer usable program code to pre-compute (10) a set of individual radiotherapeutie dose shots (aj), and associate (40) a weight (sj) to each individual radiotherapeutic dose shot (aj), based on one or more constraints (20). The processing unit (104) executes the computer usable program code to find (30) the sparsest subset of individual radiotherapeutic dose shots, so as to satisfy said one or more constraints (20).
