OVERVIEW
Product Features
The LUMISCAN ACR-2000 is a precision instrument designed to scan storage phosphor screens
and produce high quality x-ray images over a wide dynamic range with a high signal-to noise ratio.
This is accomplished by illuminating the screen with a laser as the screen is moved perpendicular to the
laser. The emitted light is collected, converted to an electrical signal and digitized to provide a 12 bit
resolution image .
*High Resolution
*High Positional Accuracy
A precision galvanometer scanner is utilized to produce a line scan that is perpendicular to the
direction of plate travel. This provides the positional accuracy required for high resolution
digitizing.
*Precision Optics
The optical system is designed to provide diffraction limited performance over the scan
envelope.
*Proprietary Light Collection System
This sets the LUMISCAN apart from other systems. The light collection system permits
collection angles of over 150 degrees at each point, allowing measurements to be extended to
low exposure areas. The collection system coupled with the detector electronics leads to a true
and precise digital representation of the image information on the plate.
This document contains a basic technical overview of the LUMISCAN ACR-2000. The optics, digital
hardware, and software subsystems are explained, as well as the systems' functionality and general user
operation. Unpacking, hardware and software installation, system specifications, service adjustments
and troubleshooting are also included. This document is intended for users who may need to
understand the principles of operation for the LUMISCAN ACR-2000.
