Densitometric measurements in coronarographic images for blood flow estimation

The paper presents the experimental validation of the coronary blood flow measured from coronarographic images. Measurements of the image intensity along the cross-section lines of the artery were performed on two sequences of coronarographic images: one with the standard injection of the contrast and the second one with the small quantity of slowly injected contrast. Experimental validation was performed using a simple artery model. The preliminary results of the flow calculation show that the error is below 19%.
