ABLATION PLANNING WITH LESION COVERAGE FEEDBACK
First Claim
1. A planning device for tumour targeting ablation planning, comprising;
- a processing unit;
an interface unit; and
a display unit;
wherein the interface unit is configured to provide at least one segmented tumour in a 3D data set to be treated in an ablation procedure; and
to provide a predetermined ablation profile;
wherein the processing unit is configured to generate a contour of the segmented tumour;
to overlap the predetermined ablation profile with at least a part of the at least one segmented tumour;
to identify an overlapping region;
to apply a predetermined safety factor at least to a part of the overlapping region to generate a modified overlapping region; and
to determine parts of the overlapping region that are arranged outside the modified overlapping region as critical overlapping portions; and
wherein the display unit is configured to display the contour of the segmented tumour;
to display the predetermined ablation profile overlapped with at least a part of the at least one segmented tumour; and
to display the critical overlapping portions in relation with the contour and the ablation profile as virtual planning ablation result.

Abstract
The present invention relates to tumour targeting ablation planning. As a facilitated and improved image-based planning method, a method (100) for tumour targeting ablation planning is provided: At least one segmented tumour in a 3D data set (112) to be treated in an ablation procedure is provided (110). A contour (116) of the segmented tumour is generated and displayed (114). A predetermined ablation profile (120) to overlap with at least a part of the at least one segmented tumour is provided and displayed (118). An overlapping region (124) is identified (122) and a predetermined safety factor (128) is applied (126) to at least a part of the overlapping region to generate (130) a modified overlapping region (132). Parts of the overlapping region arranged outside the modified overlapping region are then determined (134) as critical overlapping portions (136). The critical overlapping portions are displayed (138) in relation with the contour and the ablation profile as virtual planning ablation result (140).
