Method and apparatus for calibration of and imaging by means of an X ray imaging apparatus sensitive to the field of gravity

摘要

Method for calibrating a gravitationally sensitive image recording unit has the following steps: determination of calibration data at a number of selected base positions of the support unit with which corresponding image data at the same positions can be corrected; determination of position data relative to gravity at the corresponding base positions; and assignment of position data to calibration data in a look-up table. ??The invention also relates to a corresponding calibration device, a method for imaging using a device calibrated with the inventive method, a surgical navigation method, a data processing program and a device for implementing imagining or surgical navigation.
