A method of testing a portable x-ray device includes sensing an environmental stimulus experienced by the portable x-ray device, transmitting a signal related to the environmental stimulus to a processing unit, determining whether the signal meets an alert threshold, activating a detector of the portable x-ray device if the signal meets the alert threshold, producing a gray image through the activating step, comparing the gray image produced through the activating step with a control gray image corresponding to a properly functioning detector.
