Imaging Excellence
The Carleton DIO produces a rectangular full-frame image with a maximum field angle of 50 degrees. The DIO’s versatile optical design enhances the ability to photograph the peripheral retina, and reduces loss of contrast when media opacity is present. Observation and alignment is performed in non-mydriatic mode while image acquisition requires a low intensity pulse of visible light reducing discomfort for patients. Imaging is possible through pupils of 4mm diameter or greater, with or without dilation. Alignment is performed using a real-time full frame image on the computer screen that has indicators to assist with correct focusing and positioning. Carleton offer three software solutions for use with the DIO:
DIO live image capture software interfaces seamlessly with third party software providers.
ARC LE is a simple database and archiving solution for use with the DIO, as well as Takagi slit lamps and DSLR's for anterior segment imaging.
ARC offers a powerful imaging application offering enhanced viewing and image maniupulation options. In addition to integration with the DIO, ARC is compatible with Takagi slit lamps and most other popular models where a beam splitter and C-mount adapter are available as accessories.
ARC software can be purchased separately for those customers requiring anterior segment imaging only. Utilising a high quality megapixel Firewire camera, images are stored in raw Bayer format rather than as a pre-processed colour image. The advantage of this approach is that the post processing of images allows for excellent red-free, green-free, fluorescein and lissamine green filtering.
Key features of the ARC anterior segment system are:
- Compact C-mount 1.4 megapixel Firewire camera
- Software control of key camera parameters
- Presets for typical slit lamp imaging scenarios
- Full resolution video capture, playback and storage
- Exceptional imaging of fluorescein and lissamine green
- Session and single image export function.
- Image comparison screen for loading images recorded on different dates.
ARC software is designed to be installed as a 'stand alone' application or set up within a networked environment. Review station and additional capture station licences are available.
