Optical Frequency Domain Imaging of Ex vivo Pulmonary Resection Specimens: Obtaining One to One Image to Histopathology Correlation
1Department of Pathology, Harvard Medical School, 2Massachusetts General Hospital, 3Wellman Center for Photomedicine, Harvard Medical School, 4Pulmonary and Critical Care Unit, Massachusetts General Hospital, 5Pulmonary and Critical Care Unit, Harvard Medical School
