Method for recording medical images of a moving object

Device for evaluating medical images of a heart, comprising:

• measuring means for evaluating an available ECG signal to generate a movement signal that dynamically represents the state of movement of the heart,
• evaluating means for identifying a phase position and the frequency of the heart from the movement signal,
• recording means for recording images of the heart and reconstructing these images on the basis of the phase position and the frequency of the heart;
• and
• means for carrying out at least one further scan of the heart wherein rate of recording images is adjusted for each cardiac cycle of the heart such that same number of images are recorded in each cardiac cycle of the heart,
• wherein each cardiac cycle extends from one R-spike of the ECG signal to the next R-spike of the ECG signal, and wherein the heart is moving in irregular cardiac cycles.
