Abstract

An imaging probe for a biological sample includes an OCT probe and an ultrasound probe combined with the OCT probe in an integral probe package capable of providing by a single scanning operation images from the OCT probe and ultrasound probe to simultaneously provide integrated optical coherence tomography (OCT) and ultrasound imaging of the same biological sample. A method to provide high resolution imaging of biomedical tissue includes the steps of finding an area of interest using the guidance of ultrasound imaging, and obtaining an OCT image and once the area of interest is identified where the combination of the two imaging modalities yields high resolution OCT and deep penetration depth ultrasound imaging.
