title = "Estimation of coronary stenosis severity based on flow distribution ratios",
abstract = "We suggest improving minimally-invasive stenosis severity estimation, using a combination of existing geometry-based methods with Transluminal Attenuation Gradient measurements. Instead of local flow values, the method uses flow distribution ratios along the entire tree. The tree geometry is used to derive a lumped model and predict the {\textquoteleft}theoretical{\textquoteright} ratios in each bifurcation, while attenuation measurements are used for extracting {\textquoteleft}actual{\textquoteright} ratios. The discrepancies between the measured and the theoretical values are utilized to assess a functional degree of stenosis. Our experimental and numerical analyses show that the quantitative value of discrepancy is proportional to stenosis severity, regardless of boundary conditions.",
