SPECTRALIS OCT Angiography Module update enhances speed and expands the field of view
Heidelberg Engineering has released a new version of software for the SPECTRALIS OCT Angiography Module with significantly faster image processing time and the ability to customise the field of view to suit the level of detail required for clinical assessment.
The field of view ranges from a high resolution 10°x10° view at 5.7µm/pixel lateral resolution, which is suitable for indicating the presence or absence of flow in even the smallest capillaries, a high speed 15°x15° view and a full field 30°x15° view both at 11µm/pixel lateral resolution.
“The unique algorithm utilised in the SPECTRALIS OCT Angiography Module separates vascular flow from structural movement using a sophisticated statistical analysis that, put simply, assigns flow as white and structure as black in the image”, explains Christopher Mody, Director of Clinical Affairs. “This approach, only possible with patented TruTrack Active Eye Tracking, ensures there are no shades of grey in the OCTA image causing uncertainty due to the potential presence of structural motion. The result is high contrast OCTA images that enable you to make fast clinical decisions with confidence."
Also included in the new version is the fusion of high resolution OCT images with flow. The flow is colour-coded as yellow on the OCT image to allow you to visualise its precise location in abnormal vessels to aid assessment of pathology.
