Anthropomorphic Phantoms

Anthropomorphic phantoms are ideal substitute for teaching/training radiologic technologists

  • Permit unlimited repetition of most views… patients cannot be used for this…
  • Demonstrate effects of changing technical factors…
  • Provide valid feedback to evaluate trainee performance…
  • Because the same phantom can be used year after year, performance norms can be derived to guide training procedures…

Human skeletal architecture is duplicated more realistically with rsd skeletons than with cadaveric skeletons

  • Soft-tissue molds and skeleton molds are matched for anatomic fidelity.
  • RSD skeletons meet radiation interaction properties of both cortical bone and spongiosa as standardized by the International Commission on Radiation Units and Measurements.
  • …many cadaveric human skeletons-especially when dried out for their preparation.

pixy

the anthropomorphic training/teaching phantom

  • An anatomically and radiologically correct female
  • Small size and low weight simplify positioning
  • Can be positioned for most views
  • Permits evaluation of student performance
  • Organs accept contrast media
  • Opaque or transparent
  • PIXY ® was designed specifically for training radiologic technologists. PIXY is 5 ft. 1 in. (156 cm) tall and weighs 105 lbs (48 kg). She is repeatable, virtually indestructible and a convenient substitute for patients.

    PIXY is made of tissue-equivalent materials and has life-like articulations. Students have no difficulty in maneuvering PIXY into most desired positions.

    PIXY is used to demonstrate anatomy and evaluate positioning and imaging techniques, including kVp, mAs, contrast, optical density, OFD and TFD. Radiographs of PIXY are optically equivalent in density and contrast to human patients.

    PIXY permits unlimited exposures and tolerates trainee errors.

pixy anatomy

PIXY shoulders have ball and socket joints;
elbows and knees flex 90 ° to 100 °. Hips flex 130 ° with 30 ° hyperextension.

A “frog position” is made possible by lateral flexion at the hips. The right hand is molded with fingers positioned for an AP view, while the left hand is in an oblique-lateral position. The left foot is in full plantar flexion; the right foot is in a neutral position.

C1, C2, C6 and C7 were converted to mechanical nylon joints because educators in the field prefer full positioning capabilities for the head. The design permits the remaining neck vertebrae to be fixed in a normal position, while assuring a full range of head motion.

PIXY contains abdominal and pelvic organs: stomach, gall bladder, urinary bladder, kidneys, rectum and sigmoid flexure. These are air-filled, but accept water or contrast media and can be easily flushed after use. Custom fractures and custom pathologies are optional.
