Optical Coherence Tomography (OCT)
This light-based technique produces images similar to those of ultrasound but with a higher resolution. We currently use a commercial device to measure skin thickening in patients with systemic sclerosis. We are also developing bespoke OCT systems at the Photon Science Institute (with Mark Dickinson and Donna Arthur).
