Abstract

The invention relates to a method for a three-dimensional representation of a moving structure by a tomographic method, in which during one recording pass a series of projection recordings is registered by an imaging unit at different recording angles between a start position and an end position, it being possible to reconstruct three-dimensional image data from the projection recordings with the following steps: a) generation of tomosynthesis projection recordings along a tomosynthesis scanning path; b) interpolation of the data of the tomosynthesis projection recordings in accordance with an interpolation algorithm in order to generate a projection data set; c) use of a tomosynthesis reconstruction method on the projection data set in order to generate a tomosynthesis volume image; d) repetition of steps b) and c) for all times of interest, and e) display of tomosynthesis representations from the tomosynthesis volume images.
