Week 2: Radiographic Equipment 1 Game Plan Identify generic components of the radiographic equipment Deliverables etc DQ 1 Quiz 1 Delegate Current Event Candidates Describe various planes of x-ray tube and table movement 2 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. Radiographic Room 4 X-ray Tube Housing 5 X-RAY Tube Housing • Lead and steel • Absorbs stray radiation • Prevents x-ray photons from leaking from tube 6 Collimator Knobs 7 Collimator • Attaches directly below the xray tube • Projects a high-intensity light field on the patient, which represents the area of the xray field exposure • Serves as a beam limiting device • Controls size and shape of the x-ray field 8 Cone collimator 9 Radiographic Table 10 11 • Tilting tables – diagnostic and fluoroscopic work – 90 degrees in one direction – 15 – 30 degrees in the other direction – ancillary equipment: Tables • footboard, shoulder support, handgrips, compression bands 12 13 14 http://www.youtube.com/user/ARCOMAME D?blend=1&ob=5#p/a/u/2/C9fTjmQrfj8 15 TABLE OR UPRIGHT BUCKY TRAY 16 The ‘bucky’ is like a drawer 17 18 Intensifying screens Image Receptors and Bucky tray Film 19 Image Receptors Cassette Based Cassette-less 1) Film /screen (FS) 1)Digital Radiography (DR) 2) Computed Radiography (CR) Indirect Capture Direct Capture 20 CR Reader for Computed Radiography image receptors 21 Multiloader 22 FLUOROSCOPY: Images in motion 23 REMOTE ROOM Conventional Room 24 FLUOROSCOPY must wear shielding while x-ray beam is on Lead apron Lead Curtain 25 Tube Supports Designed to help technologists with various tube locations for creative imaging. Tube suspension systems are available in 5 versions 26 Tube Movement • • • • • • Longitudinal Transverse Vertical Angling or Rolling Rotating Telescoping 27 CONTROL CONSOLE Gives the technologist control of the xray machine Technique selection Located OUTSIDE of the Radiographic Room 28 29 The Control Console • Set technical factors (mAs & kVp) • Make an exposure • Only a legally licensed individual is authorized to energize the console 30 31 32 Other x-ray equipment • Positioning phantoms • Pixie 33 Other x-ray equipement • Positioning sponges • Lead markers 34 Positioning sponges 35 36 Gonad shields Lead Shields Lead wrap arounds Lead aprons 37 Lead Gloves and Glasses 38 Are x-ray machines prisoner to one room??? 39 Mobile X-RAY equipment • Portables – Take machine to patient – Still images • C-arm – Used in interventional procedures – Used in surgery – Dynamic images – Fluoroscopy 40 PORTABLE UNITS 41 Trauma wrist done portable - using positioning devices Lead apron TAPE sponge 42 43 44 45 46 47 Review TUBE HOUSING What is it made of? 49
