Biomedical Imaging With Fourier Domain Optical Coherence Tomography Marinko V. Sarunic Engineering Science, SFU Biomedical imaging using light is an exciting area of research for high resolution structural and functional visualization of cells and tissues in vivo. Optical coherence tomography (OCT) is an interferometric technique which provides non-invasive cross sectional images of biological tissue with micrometer scale resolution. Commonly referred to as an optical analogue to ultrasonography, the applications for OCT range from diagnostic ophthalmology to imaging in small animals and developmental biology. Recently, a significant increase in attainable OCT system sensitivity has been identified by the use of spectrally resolved Fourier domain (FD) detection. In addition to novel system level benefits for functional imaging, FD OCT facilitates high speed scanning while maintaining high image quality. In this presentation, the fundamentals of low coherence interferometry and FD OCT will be introduced, including functional imaging extensions and applications.
