Abstract
Despite promise in early pilot studies, clinical translation of intravascular PS-OCT has been limited by the complexity of incorporating polarization modulation. We present a signal processing pipeline which uses maximum-likelihood estimation to reconstruct the polarization properties of tissue measured with a single input polarization state (SIPS-OCT), enabling polarization-sensitivity with existing intravascular OCT devices. SIPS-OCT estimates both the depth resolved birefringence and optic axis orientation, with excellent qualitative and quantitative comparisons to conventional dual-input state PS-OCT. These results present an encouraging step towards removing barriers to PS-OCT adoption by enabling polarization-sensitivity in existing intravascular OCT systems.
