Digital radiography for the field: a portable prototype.

The US military has been investigating methods for improving radiographic support for field medical operations. The purpose of this project was to develop and test a portable digital radiography (DR) system to determine its feasibility for field operations. A prototype portable digital radiography device was designed and assembled using a commercially available DR sensor. The sensor and necessary hardware were mounted into a ruggedized aluminum case. The device underwent testing in the hospital and field environments. The prototype rapidly provided digital radiographs in a variety of settings. Shortcomings of the device affecting usability and reliable operation were identified. The successful construction and operation of a portable digital radiography prototype shows that such a device is feasible for field applications. The prototype requires further modification and testing to improve its usability and reliability, and to explore other potential applications, both military and civilian.
