A bifurcation identifier for IV-OCT using orthogonal least squares and supervised machine learning

Optical coherence tomography (OCT) is an imaging modality based on the technology of low-coherence interferometry. This technology has many similarities with ultrasound imaging, but instead of sound, it uses the scattering of electromagnetic radiation as the signal source. Intravascular optical coherence tomography (IV-OCT) is an in-vivo application of OCT based on the introduction of an intravascular catheter for viewing the inner wall of blood vessels. IV-OCT has many advantages over other modalities such as intravascular ultrasound, due to a superior resolution of 10μm to 20μm, which allows the visualization of tissues at the microscopic scale Prati et al.
