Researchers at the University of South Florida have developed a method to improve the wavelength scanning digital interference holography.
This technique allows non-invasive imaging of tissues such as in retina, skin and gastrointestinal epithelial tissues, with speed and enhanced capabilities. Diagnostic imaging systems, which enable clinicians to visualize the anatomic structure and evaluate the functional performance of the body’s internal organs and tissues, are indispensable in the practice of modern medicine.
