ABSTRACT:
The invention relates to a method for producing computer tomography images from limited data of a region of interest of an image object which can be subject to changes, comprising the steps ofa) producing a first computer tomography image of the region of interest (source image) by acquiring a sufficient set of projection data and using a standard CT-image reconstruction technique,b) selecting at least one transformation function depending on expected changes of the image object,c) acquiring CT-data of the image object from a limited number of projections under a limited range of observation angles,d) reconstructing a new image of the region of interest (target image) by an iterative procedure starting from the source image of the region of interest, deforming the source image by using the transformation function and optimizing the target image in view of the acquired CT-data from the limited number of projections.
