Wasatch Photonics, a provider for gratings, spectrometers and optical coherence tomography instrumentation, has launched a new imaging device, WP MicroAngio, for high-resolution angiographic imaging for research and original equipment manufacturer (OEM) applications.

MicroAngio technology allows visualisation of blood vessels at a microscopic level without using external contrast agents. The device, based on a variation of optical coherence tomography (OCT), creates a three-dimensional profile of the micro vasculature. WP MicroAngio is to be used for several medical research applications related to animal model imaging in ophthalmology, dermatology, oncology and other areas.

MicroAngio’s technique could provide an advantage over other angiography techniques like optical fluorescence and X-ray fluoroscopy. Unlike such techniques, MicroAngio doesn’t require the injection of external contrast agents that can interfere with the physiology of the sample. In addition, the technique provides 3D localised information compared to the 2D data obtained from most other existing techniques.

MicroAngio’s OCT angiography software allows users to choose from processing based on only intensity or phase of the signal, or a combination of both. The system will also provide techniques to allow for motion correction that is essential for artifact free imaging.
