Environmental Testing of the XiScan 1000, Portable Fluoroscopic and Radiographic Imaging System

Abstract : The Xi Scan 1000, Portable Fluoroscopic and Radiographic Imaging System, (Xi Tech, Inc., Windsor Locks, CT), is a hand-held unit which can be configured as a 2.6 inch, direct view fluoroscope or a standard X-ray machine for 8xlO film. This study used the System 3 package including a C-arm, cassette tray, image Intensifier, and rechargeable battery power supply which weigh 30 pounds In the commercial carrying case. Although this system could not replace existing military radiography equipment, it could enhance current capability. The fluoroscope would benefit surgeons during procedures in far-forward facilities and it could provide instant feedback to other medical personnel as to the severity of common injuries. Although the Xi Scan 1000 appears robust, it was not designed for harsh environmental conditions. For this study, a container was procured that meets the Deployable Medical Systems (DEPMEDS) packaging standard (MIL-D-42048). With this container, the system was subjected to environmental tests IAW MIL-STD-810E, Environmental Test Methods and Engineering Guidelines, to include: storage and operation at high and low high temperatures, transit shock, and vibration. After each environmental insult, performance tests were conducted to determine whether the system continued to meet specifications. Whereas the results showed the system susceptible to damage from temperature extremes and shock, the failure modes were related to design features currently being addressed by the manufacturer or involve only minor mechanical design modification.
