Received: MaAccepted: FebruPublished: March 28, 2019Ĭopyright: © 2019 Kolb et al. (2019) Live video rate volumetric OCT imaging of the retina with multi-MHz A-scan rates. Applying advanced post processing concepts for numerical refocusing or computational adaptive optics should be possible in future with such a system.Ĭitation: Kolb JP, Draxinger W, Klee J, Pfeiffer T, Eibl M, Klein T, et al. We show that this volume rate is high enough to enable a sufficiently stable optical phase to a level, where remaining phase errors can be corrected. For the first time, we present point scanning volumetric OCT imaging of the posterior eye with up to 191.2 Hz volume rate. Up to now, classical OCT was to slow for this, so our system can pave the way to holographic OCT with a traditional confocal flying spot approach. These techniques can provide additional functional information of the retina. Additionally, advanced phase-based OCT techniques require 3D OCT volumes to be detected with a stable optical phase. We show that multi-MHz A-scan rates are essential for such a device. It represents a major technological step towards the possible application of OCT-only surgical microscopes in the future which would be much more compact thus enabling many additional minimal invasive applications.
#Retina scan cost update#
We demonstrate live volumetric retinal OCT imaging, which may provide a sufficiently large volume size (330x330x595 Voxel) and high update frequency (24.2 Hz) such that the surgeon may even purely rely on the OCT for certain surgical maneuvers. To present volumetric data at a high update rate, much faster OCT systems than the ones applied in today’s surgical microscopes need to be developed. However, current commercial OCT-enhanced ophthalmic surgical microscopes provide only one additional cross sectional view to the standard microscope image and feature a low update rate. Hence, these systems can drastically improve the quality and reduce the risk of surgical interventions. The recent development of an integrated OCT system for the first time allows to look at tissue features below the surface.

You are entitled to an NHS Sight Test at intervals specified by the NHS (usually, but not always, 2 years). Please bring along your NHS card or benefits booklet as evidence of entitlement. Changes in NHS regulations since 2001 mean that we may require evidence of NHS eligibility.
