摘要： A processing device (1) and method for determining a position and/or orientation for a multi-hole grid template in a medical interventional procedure is disclosed. An anatomical spatial information processing unit (2) receives and/or processes data representative of a target spatial volume in the body, and a grid position sampler (4) generates candidate positions of the grid template. A quality calculator (5) calculates, for each candidate, a quality metric indicating the suitability of the candidate position of the grid template for the interventional procedure. A position selector (6) selects the position and/or orientation from the candidates based on the quality metric. For each candidate, an spatial relationship between each grid hole trajectory and the target volume is determined, and the quality metric takes, at least, this spatial relationship into account.

摘要： Disclosed herein is a method of operating a medical instrument (100, 200, 400, 500). The medical instrument comprises a user interface (108) with a display.
The method comprises receiving (300) an anatomical segmentation (122) identifying a location of an anatomical structure (416) and receiving (302) a target zone segmentation (124) identifying a location of a volume (416) at least partially within the anatomical segmentation. The method further comprises displaying (304) a planning graphical user interface (112) using the display. The planning graphical user interface comprises a first panel (130) configured for rendering a cross sectional view of the anatomical segmentation (136) and the target zone segmentation (138). The planning graphical user interface comprises a second panel (132) configured for displaying a first three-dimensional model (140) of the anatomical segmentation and the target zone segmentation. The planning graphical user interface further comprises a third panel (134) configured for displaying a second three-dimensional model (142) of a remaining portion of the target zone segmentation. The planning graphical user interface further comprises an ablation selector (144, 144', 146) configured for providing an ablation zone. The method further comprises repeatedly: receiving (306) the ablation zone from the ablation selector; and updating (308) the remaining portion by removing the ablation zone from the remaining portion.
