METHOD AND DEVICE FOR OBTAINING A VOLUME DATA SET OF A MOBILE TISSUE OR ORGAN OF A PATIENT |
摘要 |
<p>A method and a device for obtaining a volume data set of a mobile tissue or organ of a patient by a C-arm X-ray device are provided. An electromagnetic sensor of a position detection system is arranged indirectly on the tissue or organ. The X-ray device obtains a plurality of X-ray projections from the tissue or organ from various projection directions. A first method consists of reconstructing a volume data set from the X-ray projections, in which the electromagnetic sensor adopts a position characterizing a displacement phase of the tissue or organ. A second method consists of reconstructing a volume data set from the X-ray projections captured when the electromagnetic sensor was located in a position characterizing a displacement phase of the tissue or organ. A third method does not capture an X-ray projection for the reconstruction if the electromagnetic sensor is located in a position characterizing a displacement phase.</p> |
