Fluorescence calibration based on manual lumen detection
A method and system for calibrating fluorescence data in a multimodality image acquired from a vessel imaged by an imaging catheter. A fluorescence signal acquired by a first modality is calibrated by applying a first calibration factor based on a lumen distance and/or radiation angle from the catheter to the vessel wall. If a parameter of the calibrated fluorescence signal is different from a predetermined condition, a user is prompted to manually select a lumen boundary and/or a region of interest (ROI) on the image of the vessel. An optical attenuation property of the selected boundary and/or ROI is calculated based on backscattered radiation collected by a second modality, and the fluorescence signal is further calibrated by applying a second calibration factor based on the optical attenuation property.
