  75. Aligning the tube and Bucky.
    Detente
  76. Equipment: Cassettes or images receptor sizes:
    8x10, 10x12, 11x14, 14x17
  77. Equipment: (kVp) and (mA)
    Kilovoltage (kVp).       1kv = 1000 volts.         Controls quality of radiation

    Milliaperage (mA).       1 mA = 1/1000 amp.    Controls quantity of radiation

    mA x (s) = mAs

    Ex: (100 mA x 0.1 sec. = 10 mAs)
  78. Three Principles of Radiation Protection:
    • Time: keep exposure to a minimum
    •          X-rays (photons) travel at the speed of light
    •          Human senses can not detect radiation

    Distance: inverse square law - the intensity of radiation is inversely proportional to the square of the distance.

    Shielding: aprons, gloves, control panel. (lead, Ph)
  79. Abdomen: KUB
    Kidney Ureter Bladder (KUB)

    • Positioning:
    • 14x17 cassette, lengthwise
    • Center at the level of the iliac chest
    • Breathing instructions = expiration
