Abstract
An interface system is provided for planning a surgical procedure for inserting an object into a patient along a surgical planning trajectory from an entry point on the patient to a target point within the patient. Using an imaging device, a first scan of the patient is performed to generate a first image volume data set of a first area of the patient. A first sectional image of the patient is displayed on a human-readable display device associated with the imaging device. The first sectional image is based on the first image volume data set. Using an operator interface device, a second planning image of the patient is defined by placing a plurality of graphical point symbols in the first sectional image of the patient displayed on the display device. The plurality of graphical point symbols define a second area of the patient to be subject of display as a second sectional image of the patient. The second sectional image of the patient is derived either directly from the first image volume data set, indirectly from the first image volume data set by interpolation, or by performing a second scan of the patient with the imaging device.
