Cassettes



Cassette stands
  • Used to support cassettes for horizontal beam radiography Radiographic positioning caudocranial stifle 01 - horizontal beam.
  • Most commonly used in large animal examinations.
  • Horizontal beam radiography is used in small animals for:

Cassette holders

  • Holders on long handles are essential for large animal radiography.
  • They permit an assistant to hold the cassette while remaining well outside the primary x-ray beam.

Animal positioning

Sandbags
  • Can be made in a variety of shapes and sizes to suit any purpose.
  • Most useful shape is long and thin with loose filling so that they can wrapped around patient's appendages.
  • Commonly used in small animal radiography for:
    • Restraining animal Radiographic positioning thorax 02 - dorsoventral projection.
    • Holding limbs in particular positions Radiographic positioning tibia  fibula - lateral projection.
    • Supporting limb.
    • Preventing tilting of thorax in absence of radiographic positioning trough.

Cotton tapes

  • Ties are useful for:
    • Restraining limbs in extended position Radiographic positioning femur - craniocaudal projection.
    • Restraining contralateral limb out of the primary x-ray beam.
    • Keeping mammary tissue in females or prepuce in dogs out of primary beam during stifle radiography Radiography: stifle.

Wedges

  • Can be made in a variety of sizes and different angles for many purposes Radiographic positioning wedge.
  • Usually made from foam.
  • Used mainly to achieve true-lateral projections:

Troughs

  • Usually made from radiolucent material, ie fibre glass, foam or inflatable:
    • Essential for ventrodorsal positioning in most animals Radiographic positioning abdomen - ventrodorsal projection.
    • Dorsoventral positioning in some patients Radiographic positioning thorax 03 - dorsoventral projection (trough).

Other

Wooden blocks
  • Often padded with rubber.
  • Can be used
  • Specialized wooden blocks are used for radiography of the equine foot:
    • Cassette tunnels which protect the cassette but allow the horse to weight bear over cassette.
    • Navicular blocks on which the horse's toe rests and support the foot at specific angles alongside the cassette.

Compression bands

  • Also known asBucky bands.
  • Wide fabric strip wound onto 2 reels with a handle and ratchet to tighten band.
  • Used for:
    • Immobilization.
    • Displacement of abdominal organs.
