Method for determining at least one applicable path of movement for an object in tissue

摘要

The invention relates to a method for determining at least one applicable path (32) for the movement of an object, especially of a surgical and/or diagnostical device, in human tissue (14) or animal tissue by means of a data set of intensity data obtained by a 3D imaging technique, the applicable path (32) of movement connecting a starting position (28) of the device with a defined target location (30). According to the invention the method comprises the steps: defining the target location (30) of a reference point of the device and choosing at least one possible starting position of the reference point of the device; determining a candidate path of movement (18, 20, 22) between the corresponding possible starting position (24,26, 28) and the defined target location (30); and evaluating the candidate path of movement (18, 20, 22) as being an applicable path (32) depending on information about local intensity extrema and/or intensity variation resulting from the intensity data along the candidate path of movement (18, 20, 22). The invention further relates to a corresponding computer-readable medium, a corresponding computer program product, and a corresponding computerized system.

1. A method to determine an applicable path for a therapy, the applicable path connecting a starting position with a target position, the method comprising:
defining the target position; selecting at least one possible starting position; determining a candidate path between each position of the at least one possible starting position and the defined target position; evaluating the candidate path as being the applicable path based on intensity data obtained from unsegmented image data along each candidate path; generating an output having the applicable path; and rendering the output on a rendering device.
