METHOD FOR DEFINING A SCANNING SEQUENCE FOR RADIATION TREATMENT OF A TARGET VOLUME, BY PENCIL BEAM SCANNING (PBS) AT ULTRA HIGH DOSE DEPOSITION RATE (HDR)

METHOD FOR DEFINING A SCANNING SEQUENCE FOR RADIATION TREATMENT OF A TARGET VOLUME, BY PENCIL BEAM SCANNING (PBS) AT ULTRA HIGH DOSE DEPOSITION RATE (HDR)

The present invention concerns a method for defining an irradiation scanning sequence of spots characterizing a target area (At) of a target volume (Vt) of complex geometry, ensuring that doses (Dj) are deposited at a ultra-high dose deposition rate (HDR) onto a significant fraction of specific volu...

description The present invention concerns a method for defining an irradiation scanning sequence of spots characterizing a target area (At) of a target volume (Vt) of complex geometry, ensuring that doses (Dj) are deposited at a ultra-high dose deposition rate (HDR) onto a significant fraction of specific volumes (vi) defining a critical volume (Vc). An array of spots (Sj) is defined covering at least the target area (At). A pseudo-mediatrix (M) is determined, defining a backbone of the geometry of the target area. The spots are joined to one another to define an irradiation path (IP) as a function of the trajectory of the pseudo-mediatrix (M), to define the irradiation scanning sequence.
