Interferometric synthetic aperture microscopy: tissue structure inferred by computed imaging techniques

Interferometric Synthetic Aperture Microscopy (ISAM)1 is an optical microscopy computed-imaging technique for measuring the optical properties of three-dimensional structures and biological tissues. In this work, the principle of ISAM is reviewed, and its application to imaging tissue properties in various scanning geometries and instrument configurations is explored. The practicality of ISAM is demonstrated by imaging a rat heart and muscle using a real-time implementation of ISAM in conjunction with a clinical cart Optical Coherence Tomography instrument.
