Optical Microangiography: High-Resolution 3-D Imaging of Blood Flow

Ruikang K. Wang and Hrebesh M. Subhash

Using Fourier domain optical coherence tomography, researchers have developed a new method for producing 3-D images of microvascular blood flow.



There are many instances when doctors need to visually monitor their patients’ microvascular blood flow—including when they are diagnosing or treating cancer, heart disease and other conditions. Over the past decade, a number of technologies have emerged to meet this need, but each one has limitations. Some traumatize the tissue in a way that may seriously disturb the circulation, for example; others have practical limitations in clinical use. The ideal method of monitoring microcirculation should be noninvasive, versatile and easy to use.
