Abstract
Stenosis information is obtained by obtaining photographic image data () from a displayed image of a blood vessel () containing the stenosis. Contours of the blood vessel and the stenosis are detected and dimensions are estimated from the photographic image data. A blood vessel model is reconstructed and fractional flow reserve data is calculated using the blood vessel model.
