<p>An image processing method includes the acquisition of a succession of low-resolution images. A succession of mask images is derived from the low-resolution images. Furthermore, a high-resolution image is acquired. The mask images are applied to the high-resolution image as bandpass filters in order to form a filtered high-resolution image. The filtered high-resolution image represents image information relating to a particular phase of a dynamic process, such as the passage of blood through the vascular system of a patient. The image processing method is used, for example in MR angiography or in X-ray angiography. An MRI system or an X-ray examination apparatus is provided with an image processor for carrying out the image processing method according to the invention.</p> |
