OCT Moves from Clinic to OR to . . . Home?
Optical coherence tomography has proved its worth in the physician’s office, but now it wants to make inroads into the surgical suite as well – and possibly beyond. Optical coherence tomography, or OCT, is a rapid, noncontact, noninvasive imaging method that allows precise examination of fine layers of tissues. Although it can be used for dermatological purposes, it most often is associated with ophthalmology because it efficiently shows the details of various structures within...
