Abstract

In a method and medical imaging apparatus for determining a feature characterizing intentional breath-holding by an examination object for acquiring medical raw data with breath-holding algorithm, an algorithm, the algorithm being designed to allocate at least one feature characterizing intentional breath-holding to at least one physiological property. The algorithm includes or accesses trained artificial neural network. A physiological property of the examination object is detected during free breathing of the examination object. The feature characterizing intentional breath-holding by the examination object is determined by the computer, by executing the algorithm with the detected physiological property of the examination object, as an input to the algorithm.
