Method for analysing image data of a patient intended for automatically interpreting and/or categorizing the content of an image data set: - in a first step a first image data set of the patient is provided by an imaging instrument being a CT-, NMR-, PET- or X-ray-instrument; - subsequently, the first image data set is analysed by using a first analysis algorithm at a workstation having a processor for running the first analysis algorithm in a second step; - afterwards, in a third step, the first image data set is saved in a memory device and a piece of information about the first analysis algorithm is saved along with the first image data set; - a server having a database for analysis algorithms is provided, - wherein the first analysis algorithm and a second analysis algorithm are stored on the database and the first analysis algorithm is available on the server during the first and the second step, while the second analysis algorithm is not available during the first and the second step, - and wherein the first analysis algorithm is stored in a closed first container comprising a first run time environment (11") and the second analysis algorithm is stored in a second container comprising a second run time environment (12"), - the second analysis algorithm is added in a fourth step to the database after the second step and/or the third step, - for performing the analysis of a second image data set, the second image data set is assigned to the patient in a fifth step; - based on the piece of information saved along with the first image data set, selecting the first container from the database for analysing the second image data set, wherein the first container is transferred from the server to the workstation in a sixth step, thereby analysing the second image data set with the first analysis algorithm; and wherein: - the second analysis algorithm is an updated version of the first analysis algorithm, and - the first analysis algorithm and the second analysis algorithm are a band filter, a reconstruction from raw data, and/or a quantitative evaluation. - in a first step a first image data set of the patient is provided by an imaging instrument being a CT-, NMR-, PET- or X-ray-instrument; - subsequently, the first image data set is analysed by using a first analysis algorithm at a workstation having a processor for running the first analysis algorithm in a second step; - afterwards, in a third step, the first image data set is saved in a memory device and a piece of information about the first analysis algorithm is saved along with the first image data set; - a server having a database for analysis algorithms is provided, - wherein the first analysis algorithm and a second analysis algorithm are stored on the database and the first analysis algorithm is available on the server during the first and the second step, while the second analysis algorithm is not available during the first and the second step, - and wherein the first analysis algorithm is stored in a closed first container comprising a first run time environment (11") and the second analysis algorithm is stored in a second container comprising a second run time environment (12"), - wherein the first analysis algorithm and a second analysis algorithm are stored on the database and the first analysis algorithm is available on the server during the first and the second step, while the second analysis algorithm is not available during the first and the second step, - and wherein the first analysis algorithm is stored in a closed first container comprising a first run time environment (11") and the second analysis algorithm is stored in a second container comprising a second run time environment (12"), - the second analysis algorithm is added in a fourth step to the database after the second step and/or the third step, - for performing the analysis of a second image data set, the second image data set is assigned to the patient in a fifth step; - based on the piece of information saved along with the first image data set, selecting the first container from the database for analysing the second image data set, wherein the first container is transferred from the server to the workstation in a sixth step, thereby analysing the second image data set with the first analysis algorithm; - the second analysis algorithm is an updated version of the first analysis algorithm, and - the first analysis algorithm and the second analysis algorithm are a band filter, a reconstruction from raw data, and/or a quantitative evaluation.
