FIELD: medicine.
SUBSTANCE: invention refers to a method and a system for improved planning and radiation therapy delivery. Substance of the invention consists in planning the radiation therapy; the radiation therapy plan consists of a number of exposure doses; pre-therapeutic target volume (30) and off-target volumes images are presented; the target volume (30) and at least one off-target volume are contoured and positioned on the basis of the presented pre-therapeutic image; an exposure dose is supplied; the exposure dose contains a number of radiation beam traces and at least one radiation beam geometry; an actual exposure dose delivered to each area of the target volume (30) and at least one off-target volume is determined on the basis of the determined contours and positions and at least one radiation beam geometry; the method additionally comprises the stages, whereat supplying the exposure dose accompanies forming a number of one-dimensional therapeutic target volume (30) and off-target volumes images; the target volume (30) and at least one off-target volume are contoured and positioned on the basis of the one-dimensional therapeutic image presentation; an actual exposure dose supplied to each area of the target volume (30) and at least one off-target volume is determined on the basis of their specified contours and positions according to the presented pre-therapeutic images and presented therapeutic one-dimensional images, radiation beam traces and at least one radiation beam geometry.
EFFECT: improved exposure dose planning.
