Computer-implemented method for operating an imaging facility, imaging facility, computer program and electronically readable data carrier

The disclosure relates to techniques for operating an imaging facility for preparing an imaging process. For each imaging process, at least one image dataset is reconstructed in a reconstruction step from raw data recorded in accordance with at least one recording protocol using a reconstruction facility with reconstruction software. For advance calculation of a duration for the reconstruction step, an input dataset comprising at least one protocol parameter of the recording protocol influencing the duration of the reconstruction step and at least one hardware parameter describing the hardware of the reconstruction facility and/or at least one software parameter describing the reconstruction software is compiled, and the duration is ascertained from the input dataset by way of a trained advance calculation function, which is trained by machine learning.
