INDICIA FOR BACKSCATTER DETECTION IN PORTABLE RADIOLOGICAL DETECTORS

Embodiments of secondary backscatter indicia; digital radiography detectors and radiographic imaging apparatus using the same; and methods for using the same can detect a secondary backscatter condition for a radiation exposure. In one embodiment, a DR detector can include a housing having first and second surfaces and a plurality of walls to form a cavity; a detector array mounted within the cavity to form an electronic radiographic image; and backscatter absorbing indicia distributed in a prescribed arrangement. Embodiments of methods and/or apparatus according to the application can detect secondary backscatter radiation, can notify a technician when secondary backscatter radiation is detected in an x-ray image or can detect and/or identify portions of an active imaging area of an x-ray detector subjected to secondary backscatter radiation.
