The contrast of optical microscopy, which along with resolution, ultimately determines image quality and is enhanced in techniques such as differential interference contrast (DIC) microscopy. Our recent DIC modification-- motion-enhanced DIC, or MEDIC --further improves contrast of moving objects by creating a time-averaged background that is subtracted from each image. Now, we have developed methods for simultaneous imaging using short wavelength DIC/MEDIC and standard fluorescence microscopy. Our novel method of integrating MEDIC and fluorescence imaging provides the tag-free contrast-enhanced advantages of MEDIC and the high specificity of fluorescence microscopy. An application of this new imaging method is the localization of the same moving object in both MEDIC and fluorescence, as demonstrated in this thesis. Simultaneous localization provides a richer context for the object since it can be identified from fluorescence microscopy and its interaction with unlabeled objects can be observed by DIC and MEDIC. en Wake Forest University DIC Fluorescence Live Cell Imaging MEDIC Real Time Image Processing Simultaneous Imaging LIVE CELL IMAGING BY INTEGRATING FLUORESCENCE AND MOTION- ENHANCED DIFFERENTIAL INTERFERENCE MICROSCOPY Thesis Macosko, Jed C Seeds, Michael C Ornelles, David A Molecular Medicine and Translational Science 2013-07-09 restricted
