In order to reconstruct a composite X-ray image of larger size than the basic images obtained by radiography of the blood circulation system, the invention comprises the steps of picking-up and digitizing a predetermined number of basic images in respect of a number of relative positions between the patient-supporting table and an X-ray unit, in storing these images in a memory and in reconstructing a composite image, for example by transferring selected portions of the basic images into a collecting memory. |
