  94. Although radiology seldom yields a final diagnosis how does it contribute
    ddx list
  95. how is teh visible image or radiograph created
    Passage of ionized radiation through the body, interaction of the escaped radiation with intensifying screens, the action of subsequent emitted light with film and the effect of developing chemicals
  96. a radiograph is basically a negative, therefore the whiter or darker the film tells us what
    • darker- more overexposed
    • whiter- underexposed
  97. how does a radiograph machine create a directed beam of electrodes
    • passes electrons from a cathode through a vacuum to hit the anode giving off x rays- photons, as a beam and creating heat
    • beam leaves lead box through shuttered opening
  98. describe a radiograph cassette
    hold the radiograph film sandwiched between intensifying screens
  99. How is the object to be radiographed placed in relationship to the x ray machine and the cassette
    placed on the cassette between it and the tube head

  101. describe a radiograph
    a piece of plastic with a bilayer of silver halide emulsion
  102. how does the silver halide emulsion on a radiographic film react with x ray or light and become a radiograph
    x ray or ligh activates the silver halide, process developer crystalliees activated silver halide = silver metal, and it appears black, and sticks to the plastic, fixer clears the unreactive silver halide leaving only the plastic film
  103. What is a fluorescent light source for viewing radiographs
  104. what is a strong source of ligh placed behind the film to view overexposed areas - ie darker than desired
    spotlight or hot light
  105. what are the three things that can happen to part of the beam hitting the object
    reflection further transmission or absorption
  106. What is scatter
    relection or compton scatter- the redirection of a percentatge of the primary beam striking an object's surface
  107. What affects penetration or transmittance
    both the object's thickness and density
  108. what is the inverse square law
    intensity varies with the square of the distance or doubling the distance quarters the effective power
  109. what is divergence in relationship to radiology
    spreading the primary beam or scatter as it moves away from the source
  110. because of divergence in radiology how does placement on the cassette affect the radiograph
    closer the object to the cassette the less the divergence thus the smaller or closer to normal size and sharper the image is
  111. is an overexposed or an underexposed film better
    overexposed if not in film there is no way to get it in the film but if its in may be able to use a spot light
  112. What is denser fat or water
    water as fat floats
  113. what are the water densities seen in a radiograph
    soft tissue densities are viscera muscles and fluids, all appear similar not easily distingusihed
  114. how does the heart appear radiographically why
    soldi gray shadow disc as fluid filled ventrical not demarcated from the soft tissue walls
  115. what identiication does a film need in addition to r and l markers
    client name animal date facilty timed study and time elapsed after procedure
  116. what can be sued to properly place the animal in relation to the beam direction without having to use people
    sand bags and positional devices
  117. what are artifacts on radiographs
    not part of the animal ie dirt wet hair ointments static iodine processing mistakes and physical damage of the screens
  118. how are laterals usually taken
    med to lateral so the animal can put its limb on the cassette
  119. silhouetted caudal and cranial structures indicate the beam was directed how
    lateromedially or mediolaterally
  120. what does silhouetteed mean when discussing radiographs
    edges of a structure are contrasted against air or soft tissue
