Method for intraoperative generation of an updated volume data set |
摘要 |
To intraoperatively generate an updated volume data set in which a image information of biological tissue is volume data set representing reconstructed from a series of n 2D biological tissue x-ray projections, one version, in intraoperatively acquired m 2D biological tissue x-ray projections the biological tissue 2D contour is segmented and this is back-projected in the reconstructed volume data set. In another version, in the volume data set the biological tissue 3D contour is segmented and this is projected in intraoperatively acquired m biological tissue 2D x-ray projections. The 3D contour is visually repositioned by projection in the m 2D x-ray projections in the volume data set, until its projection is substantially congruent with the biological tissue image information in the respective 2D x-ray projections. In both versions, a volume data set updated around the intraoperatively determined biological tissue 3D contour is generated.
