Fluoroscopy Introduction

6. The photons that are emitted from the output phosphor
7. The charge of the electrostatic lenses
10. Ratio of the number of light photons at the output phosphor to the number of x-rays at the input phosphor
11. The result of insufficient amount of exposure
13. The purpose of the image intensifier
15. Result of patient dose with a magnified image

1. Phosphor that emits electrons when illuminated by light
2. Television camera tube most often used in television fluoroscopy
3. The signal to noise ratio that yields the best image
4. Size of the input phosphor that results in a magnified image (small or large)
5. Phosphor that is made of cesium iodide
8. A reduction in brightness at the periphery of the image
9. Minification gain x flux gain
12. Positively charged structure in the image intensifier
14. The function that increases mA and/or kVp based on patient anatomy
