Method, X-ray device and computer program for enhancing the image quality of images of the cardiovascular system of a patient

摘要

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).
