Teledyne e2v, an innovator of imaging solutions, has developed a new range of line scan cameras for Optical Coherence Tomography (OCT) applications in healthcare and industrial markets. The new OctoPlus range will have an immediate impact in ophthalmic OCT by reducing patient examination times and increasing the field of view available to practitioners when carrying out non-invasive eye examinations.
Image sensor pixel architecture
OctoPlus was developed following discussions with doctors and medical industry professionals. It is based on new image sensor pixel architecture and is specifically tuned to provide users with the most accurate images of the retina and cornea; mapping tissue structure, measuring thickness and visualising blood flow dynamics for diagnostics.
OctoPlus will benefit patients, doctors, and OCT equipment manufacturers by increasing patient comfort during eye tests, reducing examination time and enabling doctors to make more timely decisions. For doctors, OctoPlus will more than double the eye surface captured in a single scan without sacrificing resolution, and will improve confidence in the diagnosis protocol. This will lead to more effective treatment decisions based on OCT angiography and will allow for earlier detection of peripheral pathologies like diabetic retinopathy.
Specific advantages of OctoPlus include a 250 percent larger field of view compared to the Food and Drug Administration (FDA) approved commercial Swept Source OCT (SS-OCT) and a +5dB signal-to-noise ratio (SNR) in comparison with equipment currently available in Spectral-Domain OCT (SD-OCT).
“OctoPlus is a very exciting technology development for OCT”
A further benefit of OctoPlus is that it saves 60 percent of the power used by previous designs. This reduces heat generation, improves the stability of OCT equipment and increases maintenance intervals.
François Thouret, President of Professional Imaging at Teledyne e2v, said, “OctoPlus is a very exciting technology development for OCT. Within the next year, doctors will have wider access to functional imaging, which will benefit both patients and healthcare systems. Thinking beyond existing OCT markets, our ambition is to collaborate with partners to develop further innovation in OCT for emerging applications like neurology and dermatology.”
The launch of OctoPlus follows the introduction of Teledyne e2v’s ADQ14OCT, the first 14bit digitiser for SS-OCT, enabling high speed and high depth imaging.
