| What does caudal and cephalic mean? | Caudal means towards the feet and cephalic means towards the head. |
| Identify the components of the X-ray system | The control consol, the high voltage genrator, X-ray tube, collimator, IR, and bucky |
| What is KVp and mAs? How do they differ? | KVp (Kilovoltage peak) determines the energy pentrating the power of the x-ray mean. This can be referred to as quality. mAs (Milliampere-seconds) controls the total quantity of X-ray photons produced. |
| What us SID,OID, and and SOD? | - Source to image distance -object to image distance - source to object distance |

| SID and KVp for a routine finger | KVp of 55-65 and SID of 40" |
| Where should the CR be pointed at during a lateral thumb | The first MCP joint |
| Correct angle central ray angulation for the gaynor heart method | 20-30 degrees cephalic |
