1. A method of ablative treatment planning comprising the steps of:(A) receive three-dimensional image data set of the region of interest(b) a three-dimensional model data introduced ablation volume in a three-dimensional image data set(C) two-dimensional image is drawn containing the cross-section of the region of interest and MPR ablation volume MPR plane, using the MPR plane as the clipping plane.2. The method of ablation treatment planning according to claim. 1,wherein when drawing a two-dimensional image and the projection portion ablation volume ablation volume three-dimensional model data marked throughout MPR plane in the stencil buffer, andwherein marked parts are then mixed in a color buffer for subsequent two-dimensional image drawing.3. The method of ablation treatment planning n. 2,wherein in the first stage, the outer part of the volume of ablation is discarded so that only the inner part of the volume of ablation is marked throughout MPR plane stencil buffer, and the second stage of the internal part of the volume of ablation is discarded so that the outer part of the volume of ablation is visualized throughout MPR plane buffer stencil while pixels that are part of the outside of the ablation volume, and labeled in the first stage is discharged before mixing color buffer.4. A method of ablative treatment planning n. 2 or 3, wherein the three-dimensional model data sets of ablation volumes are entered in the three-dimensional image data set, and wherein the plurality of labeled portions corresponding to the plurality of ablation volumes, colors are mixed in the buffer so that the sections do not overlap showing the volume of ablation.5. The method of ablative treatment planning according to one of the preceding claims. 1-3, wherein prior to step (c) conversion model configured to scale, placement and / or three-dimensional model conversion data ablation volume in a predetermined direction.6. A method of ablative treatment planning according to one of t
