| Question | Answer |
| What effect does OID have on receptor exposure? | INVERSE - more OID decreases receptor exposure |
| What effect does SID have on receptor exposure? | INVERSE - more SID decreases receptor exposure |
| What factors affect DISTORTION? | SID, OID, CR Angle, Patient Thickness |
| What factors affect SPATIAL RESOLUTION? | OID, SID, FSS, Patient Thickness, Motion, CR angle |
| What is the controlling factor for CONTRAST? | kVp |
| What is the controlling factor for receptor exposure? | mAs |
| What factor affects BRIGHTNESS? | NONE - brightness is a quality of the monitor |
| What factors affect CONTRAST? | kVp, OID, Grid, Beam Restriction, Field Size, Patient Thickness, Filtration |
| What factors affect RECEPTOR EXPOSURE? | mAs, kVp, OID, SID, Grid, Beam restriction, Field Size, Patient Thickness, Filtration, CR angle, |
| What does FSS affect? | only SPATIAL RESOLUTION |
| How does increasing patient thickness affect DR factors? | DECREASES Receptor exposure, DECREASES contrast, DECREASES spatial resolution, INCREASES distortion |
| Which factors does motion affect? | DECREASES spatial resolution |
| What factors does increasing filtration affect? | DECREASES Receptor exposure, DECREASES contrast |
| What factors does increasing CR angle affect? | DECREASES Receptor exposure, DECREASES spatial resolution, INCREASES distortion |
| Which factors can the tech use to decrease distortion? | DECREASE OID, INCREASE SID, DECREASE patient thickness, DECREASE CR angle |
| Which factors can the tech use to increase spatial resolution? | DECREASE OID, INCREASE SID, DECREASE FSS, DECREASE patient thickness, DECREASE patient motion, DECREASE CR angle |
| Which factors can the tech use to decrease contrast? | INCREASE kVp, DECREASE OID, DECREASE grid ratio, DECREASE beam restriction, INCREASE field size, INCREASE patient thickness, INCREASE filtration |
| What factors can the tech use to decrease brightness? | NONE - brightness is a quality of the monitor. |
| Which factors affect visibility? | Brightness and spatial resolution |
| Which factor is the primary controller of Receptor exposure? | mAs |
