Claim 12:
13. A computed tomography device for calculating at least one examination parameter for a computed tomography examination of an area of interest of a patient, the computed tomography device comprising:
one or more processors; and
a memory storing computer-executable instructions, when executed by the one or more processors, causes the computed tomography device to
receive a topogram of the area of interest of the patient;
determine a fat distribution of the patient by applying a trained machine learning algorithm to the topogram, the fat distribution including a distribution of visceral fat of the patient and a distribution of subcutaneous fat of the patient, the distribution of visceral fat of the patient being a distribution of visceral fat of the patient along a patient length axis and the distribution of subcutaneous fat of the patient being a distribution of subcutaneous fat along the patient length axis;
calculate the at least one examination parameter for the computed tomography examination based on the fat distribution, wherein the calculated at least one examination parameter includes an x-ray tube current that is dependent on a percentage of visceral fat and a percentage of subcutaneous fat within the area of interest; and
irradiate the area of interest of the patient with x-rays from an x-ray source of the computed tomography device based on the examination parameter.
