The invention claimed is: 1. A method of testing imaging quality of a medical imaging device, comprising: sensing an environmental stimulus experienced by the medical imaging device; transmitting a signal related to the environmental stimulus to a processing unit; determining whether the signal meets an alert threshold; activating only a detector of the medical imaging device if the signal meets the alert threshold; producing a gray image through said activating; and comparing the gray image produced through said activating with a control gray image corresponding to a properly functioning detector in order to determine the imaging quality of the medical imaging device. 2. The method of claim 1, wherein the medical imaging device is a portable x-ray device. 3. The method of claim 1, wherein the environmental stimulus is a physical shock to the medical imaging device. 4. The method of claim 1, wherein the environmental stimulus is a power surge. 5. The method of claim 1, wherein the environmental stimulus is a temperature of the medical imaging device. 6. The method of claim 1, wherein the environmental stimulus is an ambient temperature. 7. The method of claim 1, further comprises providing a sensor on or within the medical imaging device, wherein said sensing comprises sensing an environmental stimulus through said sensor. 8. The method of claim 7, wherein the sensor comprises an accelerometer. 9. The method of claim 7, wherein the sensor comprises a thermometer. 10. The method of claim 1, further comprising displaying an alert graphic if the signal meets the alert threshold. 11. A system for testing imaging quality of a portable x-ray device, comprising: a portable x-ray device comprising (i) an x-ray source; (ii) a detector; and (iii) at least one sensor adapted to sense at least one environmental stimulus; and a processing unit in communication with said at least one sensor, said processing unit receiving a stimulus signal from said at least one sensor, said processing unit responsive to determine whether the stimulus signal meets a predetermined alert threshold related to damage to said portable x-ray device in order to test the imaging quality of the portable x-ray device, wherein said processing unit is responsive to activate only said detector if the stimulus signal meets the predetermined alert threshold to produce a gray image, and wherein said processing unit compares the gray image with a control gray image corresponding to a properly functioning detector. 12. The system of claim 11, further comprising a monitor in communication with said processing unit, wherein said processing unit is responsive to display an alert message on said monitor if the stimulus signal meets the predetermined threshold. 13. The system of claim 11, wherein the environmental stimulus is a physical shock to the portable x-ray device. 14. The system of claim 11, wherein the environmental stimulus is a power surge. 15. The system of claim 11, wherein the environmental stimulus is a temperature of the portable x-ray device. 16. The system of claim 11, wherein the environmental stimulus is an ambient temperature. 17. The system of claim 11, wherein said at least one sensor comprises an accelerometer. 18. The system of claim 11, wherein said at least one sensor comprises a thermometer. 19. A method of testing imaging quality of an x-ray imaging device, comprising: providing at least one stimulus sensor on or within the x-ray imaging device; sensing an environmental stimulus experienced by the x-ray imaging device through the at least one stimulus sensor, wherein the environmental stimulus includes at least one of a physical shock, power surge, temperature of the x-ray imaging device, and ambient temperature of an imaging environment; transmitting a signal related to the environmental stimulus to a processing unit; determining whether the signal meets an alert threshold; displaying an alert graphic if the signal meets the alert threshold; activating only a detector of the x-ray imaging device if the signal meets the alert threshold; producing a gray image through said activating; and comparing the gray image produced through said activating with a control gray image corresponding to a properly functioning detector in order to determine the imaging quality of the x-ray imaging device.
