Specifications NOMENCLATURE: X-Ray Diagnostic System The minimum essential physical, functional and performance characteristics for a new X-Ray Diagnostic System are:

· Must be able to measure and display radiation exposure in units of roentgen and radiation dose in units of gray (and appropriate subunits).

· Must measure and display dose (exposure) rate with a visual indicator that measurement is occurring. The measurement interval over which the dose is measured and displayed shall be between 0.3 and 5 seconds.

· Must have a mode to be able to measure and display maximum dose rate, if the measured rate is greater than the displayed value.

· Must be able to manually start dose measurements commonly called “dose accumulate and hold” and display the result.

· Must be able to automatically measure and display the dose and duration of a single exposure (“auto dose”).

· Must be able to be use both ion chambers and solid state dose sensors.
