Claim Text:
1. A medical image processing system, comprising: analytical devices for generating patient images of a patient; and a computer for determining data which are referred to as atlas data and comprise information on a description of an image of a general anatomical structure, wherein this image is referred to as an atlas image, the computer being constituted to perform following steps: acquiring patient data which comprise a description of a set of one or more of the patient images of an anatomical structure of a set of one or more patients, wherein the set of one or more of the patient images being referred to as patient image set and each patient image is associated with a parameter set which comprises one or more parameters which are obtained when the patient images are generated, wherein the one or more parameters influence representations of anatomical elements as expressed by image values in the patient images, the patient data comprising the patient image set and the parameter sets associated with the patient image set; acquiring model data which comprise information on a description of an image of a model of an anatomical structure of a patient which is referred to as the model image and is associated with the parameter set; wherein the model of an anatomical structure is referred to as the model structure and comprises a model of at least one anatomical element which is referred to as model element; wherein the model data comprise: wherein acquiring the model data involves determining, on the basis of the model data and the patient data, a set of one or more of the model images which respectively represent at least a part of the model structure by using the spatial information on the model structure and particular model representation data sets which are determined by applying the determination rule in accordance with the one or more associated parameter sets and at least one particular model element referred to as corresponding model element, which is to be matched to at least one corresponding anatomical element represented in the patient image and referred to as patient element, the set of one or more of the model images being referred to as model image set; determining matching transformations which are referred to as PM transformations and which are constituted to respectively match the patient image set to the model image set by matching images associated with the same parameter set; determining an inverse average transformation by applying an inverting and averaging operation to the determined PM transformations; and
