| Question | Answer |
|---|---|
| Q: What does angling the CR 25 degrees cephalic mean? | A: The central ray is directed 25 degrees toward the patient’s head. |
| Q: What does caudal (caudad) mean? | A: Toward the feet. A caudal CR angle points the beam toward the feet. |
| Q: Define proximal and distal. | A: Proximal = closer to the trunk. Distal = farther from the trunk. Example: elbow is proximal to the wrist. |
| Q: What are the two classifications of the human skeleton? | A: Axial (skull, spine, ribs, sternum) and appendicular (limbs plus shoulder and pelvic girdles). |
| Q: What is the Trendelenburg position? | A: Recumbent with the head lower than the feet. |
| Q: Define supine and recumbent. | A: Recumbent = lying down. Supine = lying on the back, face up. |
| Q: Name the main body planes and why they matter in radiography. | A: Sagittal (left/right), coronal (front/back), transverse (top/bottom). They guide CR direction and part rotation. |
| Q: Why use positioning landmarks? Name three. | A: They help center the CR when you can’t see internal anatomy. Examples: jugular notch, iliac crest, ASIS, 3rd MCP joint. |
| Q: What are routine positions for most upper extremities, and why? | A: Two views 90° apart (usually PA/AP and lateral; some parts also need obliques) so fractures and overlap aren’t missed. |
| Q: How do you adjust kVp for a fiberglass cast? | A: Increase about 3–4 kVp. Plaster needs more (about +5–7 small/medium, +8–10 large). |
| Q: What is AEC and how does it help safety? | A: It stops the exposure when the detector has enough radiation. That keeps dose more consistent if the part is centered correctly. |
| Q: When and why are grids used? | A: When the part is thicker than about 10 cm or kVp is high. Grids soak up scatter and improve contrast. |
| Q: List main parts of an x-ray system. | A: Tube, collimator, generator/console, table or upright Bucky, and image receptor. |
| Q: How do tables and tube supports differ? | A: Tables can be fixed, floating, or tilting. Tube supports can be floor-mounted, ceiling-mounted, or C-arm. |
| Q: Where do you center the CR for a PA hand and a PA wrist? | A: Hand: 3rd MCP joint. Wrist: midcarpal area. |
| Q: Define supination and pronation. | A: Supination = palm up. Pronation = palm down. |
| Q: Why align the long axis of the part with the IR? | A: So the image hangs correctly, uses the receptor well, and left/right errors are less likely. |
| Q: A CR angled toward the head is a _____ angle; toward the feet is a _____ angle. | A: cephalic; caudal |
