Abstract

Fluorescence diffuse optical tomography (FT) is a promising molecular imaging technique that can spatially resolve both fluorophore concentration and lifetime parameters. In this phantom study, we built a photo-multiplier tube (PMT) based single detection system that uses fiber bundles to collect light. Measurements were acquired both with a 1 mm diameter single fiber and a 6 mm diameter fiber bundle using the very same detection unit for comparison purposes. We demonstratethat the fluorescence concentration and lifetime can be well recovered for 6 mm diameter objects deeply embedded in an 80 mm diameter breast-sized phantom when the fiber bundle is utilized.
