NIDEK has launched AngioScan, an upgraded OCT-Angiography software, that enables visualisation of retinal and choroidal microvasculature and blood flow using the RS-3000 Advance 2 Optical Coherence Tomography.
“The new analysis function quantifies vessels in each layer providing metrics to assess disease progression and the effects of treatment. The NIDEK AngioScan [also] presents a vessel density map and a perfusion density map. Additionally, the foveal avascular zone (FAZ) is automatically detected and shape metrics are provided for rapid assessment,” said a company spokesman.
“A newly designed interface displays seven slabs for each layer on one screen. The interface is intuitive and summary charts facilitate quick evaluation of the most relevant clinical features.”
Improved image-processing algorithms enable visualisation of sub-clinical neovascularisation. New projection artifact removal algorithms provide an accurate representation of vasculature by reducing artifacts for better OCT-angiography image interpretation,
