4.1 Product Overview
The LUMISCAN ACR-2000 READER is a single-image plate laser scanner designed to scan and digitize
the latent image from medical storage-phosphor image plates. The system is based on a fixed size scanning
spot and can scan up to 2048 pixels across image plates of 18 to 35 cm in width. This is achieved with a
high intensity spot of light derived from a high-power red laser diode which is scanned across the image
plate surface as the image plate is moved perpendicular to the beam scan. The stimulated light is collected
and digitized to provide an image file that can be stored on disk, transmitted to other systems for processing
and manipulation, archived, and/or printed back film.
The LUMISCAN ACR-2000 READER is a basic scanner with no image plate handling and is intended to
be used in a darkened room environment. The image plate must be removed from the cassette and placed
into the feed slot in order to be scanned. When the scan is complete the image plate must be removed from
the exit tray and erased by placing into the external eraser, then reloaded into its cassette for the next use.
