MiniMAX: A Compact, Portable X-Ray System For Field Inspection

MiniMAX takes x-ray images that are as detailed or even better than conventional hospital systems. However, unlike such systems, MiniMAX is easy to use, portable, lightweight, and inexpensive. MiniMAX takes advantage of the form factor of x-ray film, the physics of computed radiography (CR), and the compact technology of digital radiography (DR) panels to implement the benefits of each in a very simple, reliable, and compact system.

MiniMAX: A Compact, Portable X-Ray System For Field Inspection

Summary:

MiniMAX takes x-ray images that are as detailed or even better than conventional hospital systems. However, unlike such systems, MiniMAX is easy to use, portable, lightweight, and inexpensive. MiniMAX takes advantage of the form factor of x-ray film, the physics of computed radiography (CR), and the compact technology of digital radiography (DR) panels to implement the benefits of each in a very simple, reliable, and compact system.

Abstract:

The use of x-rays for inspection is ubiquitous, and yet large, expensive, fixed facilities are presently required to accomplish this important task. We present the design of a unique, lightweight, compact, low-cost, x-ray system: MiniMAX (Miniature, Mobile, Agile, X-ray) along with typical radiographic data obtained in our trials. This system exploits the best aspects of Computed Radiography (CR) and Digital Radiography (DR) technology. In contrast to a conventional, flying-spot scanner, MiniMAX records a photostimulated emission-image from a CsBr or BaFBr:Eu storage phosphor using a single flash from a bright, red LED filtered through an extremely efficient (OD>9) dichroic filter. When combined with compact, sealed, radioisotopic x-ray sourse (eg. 57Co, 75Se, 99Ir, or 60Co), the complete system weighs less than 6 lbs and is suitable for inspecting sealed containers, facilities, and cargo. Because digital images are made immediately available, these can be readily uploaded and analyzed on a tablet computer.

Concept:

Computed Radiography (CR) uses the principle of photostimulation (bottom) to record an x-ray image onto a storage phosphor material. Conventional scanners (top) use a raster-scanning laser to provide the red photostimulation light . The blue emission light is then collected on a point-wise basis using a photomultipiler tube.

With MiniMAX (middle), the entire storage phosphor is illuminated at once with a bright-red LED flash source and only the blue, emission light passes through a dichroic filter forming an image onto a CCD.
