- 6. A positively charged electrode within the x-ray tube composed of copper, tungsten and graphite
- 9. Lack of sharpness resulting from patient motion
- 10. Light box for viewing radiographs
- 12. Electromagnetic radiation that has neither mass nor electric charge but interacts with matter as though it were a particle
