Abstract:
1. A method for operating medical imaging apparatus selected from the group consisting of computed tomography apparatuses and C-arm x-ray apparatuses, that obtains a medical image exposure of a patient, said medical image exposure encompassing a plurality of regions in the patient, comprising the steps of: defining a plurality of input parameters, dependent on a normalized input parameter, that respectively associate a desired image quality with said regions; defining a plurality of control parameters respectively corresponding to the input parameters, that respectively control irradiation of the respective regions by said medical imaging apparatus; and operating said medical imaging apparatus according to said control parameters to obtain an image exposure comprising said regions with each region receiving a localized radiation dose that causes that region to have an image quality in the overall image exposure as defined by an input parameter for that region among said plurality of input parameters.
