Abstract

A system for determining a cross-sectional geometry of a vessel (110), is provided. The system includes one or more processors. The processor(s) receive intravascular imaging device data representing a cross sectional geometry (w₁, h₁) of the vessel (110). The processor(s) also receive fluoroscopic data (150). The fluoroscopic data includes one or more fluoroscopic images representing the intravascular imaging device (140) in the vessel (110) during the generation of the intravascular imaging device data (130). The fluoroscopic image(s) are registered to the angiographic image(s) to determine an orientation (α, β) of the intravascular imaging device (140) with respect to the vessel (110) in the angiographic image(s). The cross sectional geometry (w₁, h₁) of the vessel (110) is then adjusted based on the orientation (α, β) of the intravascular imaging device (140) with respect to the vessel (110) in the one or more angiographic images. The adjusted cross-sectional geometry (w'₁, h'₁) of the vessel (110) is then outputted.
