Radiographic equipment

• (1) X-ray tube-
• - anode/cathode
• - tube stand allows for sliding-longitudinal,
  transverse, and vertical.

3

• (2) Collimator-
• below x-ray tube- controls size and shape of
  x-ray field-
• use a light source to project a representation
  of the x-ray field onto the patient.
• Automatic collimation- PBL-positive beam
  limitation
• - Built in tape measure to check SID

4

• (3) X-ray table- tilt, non-tilt, free floating or
  stationary and height adjustable or
  nonadjustable.
• Tilt from horizontal to vertical
• Bucky tray- below table, holds x-ray cassette,
  can be manually moved the entire length of the
  table and locked into place

5
Console- cockpit of an airplane- command of the
x-ray machine- set exposure factors. 5 main
controls- power switch, kVp, mA, timer and
rotor-exposure switch
6
console

• kVp- 1 kv1000 volts
• minor and major knobs range 30-150 kvp
• mA- 1 mA 1/1000 of an ampere-
• amt of current- range 100-400 mA for dx
  radiography
• Time- seconds- 25 increments
• mAs- how many x-rays for how long
• Exposure- activate the rotor to begin- cause
  anode to rotate-prepare tube for exposure-second
  switch takes the exposure- automatic timer shuts
  it off.

Wall mounted Bucky

• Standing patients
• Pull out tray and place cassette in the tray and
  lock it in place- can move entire Bucky system
  along vertical plane.
• Alignment- table, tube and Bucky all move
  separately- be careful to check after positioning
  the patient that all parts are in alignment.

Components of Fluoroscopy

• X-ray tube- located under x-ray table
• opposite from the tube-image intensifier-
  intercept attenuated beam-transform into
  electronic image.
• Television monitor displays the image
• Radiologist views a physiologic event

The image is DYNAMIC Radiologists take spot
films of the process. Technologist takes
overheads after fluoro There is mobile fluoro
