Okoro, Chukwuemeka Onyekere 2015-07-22T22:33:59Z 2015-07-22T22:33:59Z 2017-07-23T09:15:34Z 2015-05 2015-04-30 Second-harmonic generation microscopy takes advantage of second-order nonlinear property for imaging of biological structures. Invoking quantitative image analysis techniques facilitates the assessment of tissues in varying states. This thesis presents a quantitative description of the relative structural difference in collagen-based tissues by second harmonic generation (SHG) imaging techniques involving polarization investigation. The Mueller matrix formalism demonstrates a polarization-based analysis approach for assessment of varying samples. The associated second-order Mueller matrices are generated by applying image processing algorithms to sub-grids of image sets obtained from a forward imaging microscope. By defining scalar metrics such as the degree of polarization and the depolarization, a quantitative evaluation of the samples under investigation is provided. A discussion of the capabilities for tissue assessment and techniques for improvements in the data acquisition speed and analysis will also be proffered Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-05-01 The student, Chukwuemeka Okoro, accepted the attached license on 2015-04-28 at 11:11.
