ARC is an advanced ophthalmic imaging system offering significant performance enhancements over conventional technologies. It uses large format CCD sensors, greatly reducing the loss of focus commonly experienced when magnifying high pixel count camera images.
Along with high optical resolution, these large format sensors offer high levels of infrared and ultra violet sensitivity. ARC stores images to disk as raw Bayer image sensor data rather than a pre-processed colour image. Images are then interpolated to colour when viewed or exported from the database. An unprocessed Bayer image occupies only one third of the disc space of the resultant RGB image negating the need for compression. As all colour balance calculations are performed post acquisition ARC provides excellent red free and green free filtering, the raw sensor data being reprocessed prior to interpolation. This data storage technique allows live mega pixel video capture at resolutions typically 400% higher than standard video cameras.
Live retinal video capture is now also possible using the latest scanning digital ophthalmoscope technologies for both colour and fluorescein angiography video production. As ARC directly controls the imaging sensor, preset parameters for specific tasks such as fluorescein imaging are automatically programmed into the camera when selected, offering “WYSIWYG” (What you see is what you get) imaging. ARC upgrades are available for many existing imaging systems including fundus cameras that were previously not considered suitable for digital imaging. ARC image capture and storage software is available with various patient database and practice management options and can be easily interfaced with existing patient databases
