We present a unique, lightweight, compact, low-cost, x-ray imager: MiniMAX (Miniature, Mobile, Agile, X-ray). This
system, which exploits the best aspects of Computed Radiography (CR) and Digital Radiography (DR) technology,
weighs less than 6lbs, fits into a 6" diameter x 16" long carbon-fiber tube, and is constructed almost entirely from offthe-
shelf components. MiniMAX is suitable for use in weld inspection, archaeology, homeland security, and veterinary
medicine. While quantum limited for MeV radiography, the quantum-efficiency is too low for routine medical use.
Formats include: 4"x6", 8"x12", or 16"x24" and can be readily displayed on the camera back, using a pocket projector,
or on a tablet computer. In contrast to a conventional, flying-spot scanner, MiniMAX records a photostimulated image
from the entire phosphor at once using a bright, red LED flash filtered through an extremely efficient (OD>9) dichroic
filter.
