					Radiographic and
  Fluoroscopy
   Equipment
Radiographic equipment:

      (1) X-ray tube-

       - anode/cathode

       - tube stand allows for sliding-
       longitudinal, transverse, and vertical.
(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
   (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
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
console

   kVp- 1 kv=1000 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 equip- C arm-
OR,IR..
