System and computer program product for radiation inverse treatment planning

A computer program product, comprising:

• a tangible computer usable medium including computer usable program code for a radiation inverse treatment planning system comprising a radiation source configured for delivering individual dose shots, each individual dose shot having a predetermined location and incidence angle inside and/or outside a target area, a size and a shape, the computer usable program code being used for
• pre-compute a set of individual dose shots,
• associate a weight to each individual dose shot, based on one or more constraints,
• characterised in that the processing unit executes the computer usable program code to
• find the sparsest subset of individual dose shots so as to satisfy said one or more constraints.

A computer data carrier storing presentation content created with a radiation inverse treatment planning method, comprising the following steps:

• pre-compute a set of individual dose shots, each individual dose shot being generated by a radiation source and having a predetermined location and incidence angle inside and/or outside a target area, a size and a shape,
• associate a weight to each individual dose shot, based on one or more constraints,
• characterised in that the processing unit executes the computer usable program code to
• find the sparsest subset of individual dose shots so as to satisfy said one or more constraint.
