摘要：
In a method to assist in the selection of an acquisition configuration from a set of adjustable acquisition configurations for the acquisition of x-ray projections of the heart of a patient with a computed tomography apparatus to examine the heart of the patient, the which method is based on an examination type to be specified. At least two acquisition configurations for the specified examination type (which acquisition configurations can be adjusted at the computed tomography apparatus) are considered for which at least one probability density function is respectively kept ready that was determined for the respective acquisition configuration for a specific variable pertaining to a person and/or for the x-ray dose to be applied to the person. Using the at least two probability density functions, the acquisition configuration that is best suited for the examination of the heart of the patient according to the specified examination type is determined from the at least two adjustable acquisition configurations under consideration, based on at least one determined variable to be specified and pertaining to the current patient to be examined and/or based on a value pertaining to the applied x-ray dose. The invention also concerns a computed tomography apparatus operable according to such a method and a storage medium encoded with programming instructions for implementing such a method.
