摘要
In a method and apparatus for segmentation of an examination region to be imaged, scan projection data are acquired from the examination region to be mapped. Iterative reconstruction takes place on the basis of the acquired scan projection data. Preliminary image data and preliminary textural features are reconstructed. Anticipated preliminary structures, preferably preliminary contours, are determined in the examination region on the basis of the obtained preliminary textural features. The anticipated preliminary structures are then taken into account during iterative reconstruction of preliminary image data and preliminary textural features. An image segmentation method is described, moreover. An image reconstruction device is also described.
