Abstract
A system and method for monitoring progress of a radiographic exposure is disclosed. The system samples the cumulative radiation as an exposure progresses, and aborts the exposure if the rate of rise in cumulative radiation is insufficiently low to cause a good exposure. Similarly, the system will terminate an exposure early, at a properly timed out interval, even if the radiation accumulation rises excessively fast due to an erroneous system set up.
