Method for determining receiving direction of C-arm angiography system of two-dimensional X-ray image of lung of tumor patient, involves determining receiving direction which is coaxial with axis and/or take-up direction

摘要

The method involves determining (103) position within bronchial portion of bronchial system close to tumor. The position is selected such that proximal end of bronchoscope is inserted into bronchi portion with integrated extendable biopsy instrument to position. The axis defined by position and predetermined or calculated point in tumor is determined (104) in segmented three-dimensional image data. The receiving direction which is coaxial with axis and/or take-up direction which is aligned orthogonal to axis is determined (105). The recording direction is outputted (106).
