INTRAVASCULAR IMAGING DIAGNOSTICS

There is provided a system and method for recommending a treatment of a vessel. The system is for use in conjunction with an intravascular imaging system which obtains images of the vessel and measures the position of each image along a longitudinal length of the vessel. The system comprises a processor adapted to receive a plurality of intravascular images of the vessel and respective positions along the vessel, determine, from the images, a cross sectional area of a section of the vessel at a plurality of positions along the vessel, determine, from the images and the respective position of the images along the vessel, a flow resistance of the vessel, and output a treatment recommendation based on the cross sectional area of the vessel and the flow resistance of the vessel.
