Week 2: Radiographic Equipment

1. Week 2: Radiographic Equipment

2. Game Plan • Identify generic components of the radiographic equipment • Describe various planes of x-ray tube and table movement • Deliverables etc • DQ 1 • Quiz 1 • Delegate Current Event Candidates

3. X-Ray Machine Design Features • X-ray tube and x-ray tube support • Collimator assembly • X-ray table • X-ray generator and control • Upright image receptor Fig. 8-3 Radiographic system with variable-height radiographic table. The table is in a lowered position.

4. Radiographic Room

5. X-ray Tube Housing

6. X-RAY Tube Housing • Lead and steel • Absorbs stray radiation • Prevents x-ray photons from leaking from tube

7. Collimator Knobs

8. Collimator • Attaches directly below the x-ray tube • Projects a high-intensity light field on the patient, which represents the area of the x-ray field exposure • Serves as a beam limiting device • Controls size and shape of the x-ray field

9. Cone collimator

10. Radiographic Table

12. Tables • Tilting tables • diagnostic and fluoroscopic work • 90 degrees in one direction • 15 – 30 degrees in the other direction • ancillary equipment: • footboard, shoulder support, handgrips, compression bands

16. TABLE OR UPRIGHT BUCKY TRAY

17. The ‘bucky’ is like a drawer

19. Image Receptors and Bucky tray Intensifying screens Film

20. Image Receptors Cassette Based 1) Film /screen (FS) 2) Computed Radiography (CR) Cassette-less 1)Digital Radiography (DR) • Indirect Capture • Direct Capture

21. CR Reader for Computed Radiography image receptors

22. Multiloader

23. FLUOROSCOPY: Images in motion

24. REMOTEROOM Conventional Room

25. FLUOROSCOPYmust wear shielding while x-ray beam is on Lead apron Lead Curtain

26. Tube Supports • Designed to help technologists with various tube locations for creative imaging. • Tube suspension systems are available in 5 versions

27. Tube Movement • Longitudinal • Transverse • Vertical • Angling or Rolling • Rotating • Telescoping

28. CONTROL CONSOLE • Gives the technologist control of the xray machine • Technique selection • Located OUTSIDE of the Radiographic Room

30. The Control Console • Set technical factors (mAs & kVp) • Make an exposure • Only a legally licensed individual is authorized to energize the console

33. Other x-ray equipment • Positioning phantoms • Pixie

34. Positioning sponges Lead markers Other x-ray equipement

35. Positioning sponges

37. Gonad shields Lead Shields Lead wrap arounds Lead aprons

38. Lead Gloves and Glasses

39. Are x-ray machines prisoner to one room???

40. Mobile X-RAY equipment • Portables • Take machine to patient • Still images • C-arm • Used in interventional procedures • Used in surgery • Dynamic images • Fluoroscopy

41. PORTABLE UNITS

42. Trauma wrist done portable- using positioning devices Lead apron TAPE sponge

48. Review

49. TUBE HOUSING What is it made of?
