<p>The invention covers a method to determine the relative lung perfusion image with the fluoroscopic principle. Transmitted X-ray radiation through the lungs of the patient under examination is measured at least during one heart cycle. An image intensifier is used to collect the images which are digitized, taken to the apparatus and further analysed. The results are the grey scale image and numerical map depicting the lung perfusion distribution.</p> |
