ZEISS CIRRUS HD-OCT 4000 OCT

Description

ZEISS CIRRUS HD-OCT 4000

The ZEISS CIRRUS HD-OCT 4000 OCT allows examination of the posterior and anterior of the eye at an extremely fine spatial scale, without surgical biopsy or even any contact with the eye. Employing the advanced imaging technology of spectral domain optical coherence tomography, Cirrus HD-OCT acquires OCT data about 70 times faster (27,000 vs. 400 A-scans per second) and with better resolution (5 μm vs. ~10 μm axial resolution in tissue), compared to first-generation OCT technology.

ZEISS CIRRUS HD-OCT 4000 OCT acquires whole cubes of OCT image data, composed of hundreds of line scans, in about the same time as Stratus acquires a six-line scan. You can view these data cubes in three planes, or through three dimensions, giving you access to an extensive amount of retinal image data in one scan.

KEY FEATURES

Built on 10 years experience at the vanguard of innovation, Carl Zeiss Meditec OCT technology has become the recognized standard of care. Now, Cirrus HD-OCT offers another leap forward with a superior platform that delivers unprecedented imaging details for clinical decision making.

• ZEISS optics provide superior visualization of anatomical details across a wider range of patients.
• Robust engineering with premium components ensures consistent precision performance.
• Unique HD layer maps and images highlight clinically relevant details for identification and monitoring of specific diseases – all at a glance.

The powerful Cirrus HD-OCT scan engine delivers superior image data. The new HD Enhanced Raster Scan leverages this power to produce images with outstanding detail while maintaining patient throughput. The proprietary Selective Pixel Profiling™ technology enhances anatomical features while reducing image noise.

Cirrus HD-OCT enables repeatable visualization of clinically relevant anatomy with exact correlation between the OCT scan and the fundus image. Comprehensive navigational tools ensure efficient and simple operation.

ZEISS CIRRUS HD-OCT 4000 OCT DESIGNED FOR EFFICIENCY

• Small footprint and integrated design are ideal for crowded or busy practice
• 90 degree orientation facilitates observation of patient throughout exam
• Advanced optics aid in the examination of patients with cataracts
• Dilation is not required even for pupils as small as 2.5 mm
• Mouse Driven Alignment™ delivers superior image capture and analysis in just a few clicks, resulting in reduced chair time for the patient
• Auto Patient Recall™ assures patient position and instrument setting are repeated from previous visit
