A Novel Hand-Held Optical Imager with Real-Time Coregistration Facilities Toward Diagnostic Mammography

Abstract

Hand-held optical imaging devices using near-infrared (NIR) light are currently developed toward clinical translation of the technology. However, none of the devices developed to date have been used toward 3D tomography since they are not able to coregister the image to the tissue geometry. The objective for the work described herein is the clinical translation of a hand-held optical imager with automated coregistration facilities toward 3D tomography. Studies were performed in vivo with healthy female volunteers. A spherical target filled with a fluorescent contrast agent was placed superficially underneath the breast tissue to represent a tumor. Images were collected and coregistered using the hand-held imager. The data from the coregistered image was used to generate a 3D image of the target within the breast tissue. The results show for the first time the feasibility of performing 3D tomography in human breast tissue using a hand-held optical imager.
