Spectral-Domain with Dual Beam Eye Tracking
The most demanding retinal cases deserve the best in comprehensive diagnostic assessment. Spectralis® combines the best of confocal scanning laser ophthalmoscopy (cSLO) and spectral-domain OCT (SD-OCT). Simultaneous fundus imaging and spectral-domain OCT offer high quality images with the certainty of knowing location.
Whether it is glaucoma, pre-op surgical assessment or adjusting anti-VEGF therapy, confidently detecting and assessing small changes may change your treatment decision. In diagnostic imaging, motion artifact is the number one problem limiting confident detection of small change.
Spectralis® solves this problem by using cSLO technology to track the eye and guide OCT to the selected location. TruTrack™ Eye Tracking comes from a long history of image alignment know-how, validated in longitudinal studies such as the Ocular Hypertension Treatment Study. Not only are the scans guided on first examination, TruTrack™ automatic retinal recognition technology enables follow-up examinations to be scanned in the same exact location without relying on subjective operator judgment.
In the new era of spectral-domain OCT, fast scanning speed is not enough. Just like Dolby® noise reduction eliminates static in sound recordings, Heidelberg Noise Reduction technology eliminates speckle (static) in images, revealing fine detail in the retinal layers.
Combining eye tracking with noise filtering technology enables the Spectralis® to produce stunning new images of all of the retinal layers. New anatomical structures are already being uncovered which may lead to a better understanding of disease and help guide therapeutic decisions.
As with all Heidelberg Engineering products, the Spectralis® is a flexible, upgradable and multi-application platform. Three different models with either 2, 5 or 6 imaging modes are available so the clinician can select the right combination for their practice needs.
Upgradeable technology has been the hallmark of Heidelberg Engineering. It is the only scanning laser company which has stood behind multiple generations of instruments without obsolescing data acquired from earlier versions.
Spectral-domain OCT is adding volumes of new information. In fact, 3-D volume scans are becoming the standard imaging method for assessing the retina. Printed reports cannot display 3-D data and movies the way a computer monitor can, so Spectralis® is pre-installed with remote viewing capabilities. Clinicians are able to review images at their desk and laptop, and even display them on large monitors for educating patients.
Multi-modality imaging on a single platform means that patients get all modes at a single point, increasing throughput and enabling on-the-spot changes when discovering unexpected pathology.
Spectralis® OCT will take your breath away. Large, detailed fundus images captured simultaneously with ultra high resolution OCT scans. We have combined the best of confocal scanning laser ophthalmoscopy with the fastest spectral-domain OCT to bring you the highest performing and most flexible imaging platform available.
More than just high resolution OCT, the Spectralis® tracks the retina using one beam and “locks-on” to guide the location of the second beam’s cross-sectional image. This eliminates the uncertainty of scan location and motion artifact found in systems which are dependent on so-called “real time” registration.
Tracking Laser Tomography is different than single beam “OCT only” systems. By combining the best of confocal scanning laser technology (cSLO) and spectral-domain OCT, the Spectralis® not only guides the images to the retina on the first scan, it can be used to guide the follow-up exam. The system uses the doctor’s decision on scan location, automatically scanning in the same location on follow-up and does not rely on the operator’s subjective judgment.
The real breakthrough in imaging has not been “high resolution” imaging, it is the ability to minimize or eliminate eye motion artifact, enabling highly detailed images of retinal pathology. Having the fastest scan speeds, combined with TruTrack™ dual beam scanning, enables Spectralis® to outrun most saccades which cause motion artifact in other 3-D OCT images.
The 2-mode and 5-mode versions can be upgraded to 6 modes at a later date as your practice needs change.
