The invention relates to a method, a device and a program for enhancing the image quality of images of the cardiovascular system of a patient which are produced by means of an X-ray device which includes a pulse generator for producing successive images at a given rate. The method includes the steps of: a) measuring the activity of the heart of the patient, b) controlling the pulse generator on the basis of the heart activity, and also the steps of: c) adjusting the desired number of images per heart beat, d) calculating an instant for issuing a pulse on the basis of the heart activity as measured in the step a) and the number of images per heart beat as adjusted in the step c), e) determining the amount of the X-ray dose per pulse, and f) controlling the generator on the basis of the pulse issue instant as calculated in the step d) and the amount of the X-ray dose as determined in the step e).
