The Anthropomorphic Teaching/Training Phantom 

  

  •  A small adult female to facilitate handling
  • Can be positioned for most views
  • Permits evaluation of student performance
  • Organs accept contrast media
  • Opaque or transparent

PIXY is a small, female, anthropomorphic phantom designed specifically for training radiologic technologists. PIXY is 5 ft. 1 in. tall and weighs 105 lbs. She is a repeatable, virtually indestructible and convenient substitute for patients. 

She 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 technique, 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 plantarflexion; the right foot is in a neutral position. 

Cl, 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 accept air, water or contrast media and can be easily flushed after use. Custom fractures, custom pathologies and arterial trees are optional. 

PIXY MATERIALS 

Soft Tissues 

PIXY is available in opaque or transparent tissue-equivalent materials. The transparent PIXY has visible organs and skeleton except at the hips, knees, and elbows, which are opaque because, as on the opaque PIXY, latex coverings are needed to retain tissue-equivalent gels for soft-tissue continuity at these articulations. Two-ply coverings protect against gel leakage. 

Lungs 

Standard PIXY lungs are tissue-equivalent foam with a mass density of inflated human lungs (0.30 g/cc). They are connected to the oro-nasal cavity by the stem bronchi and trachea. The oro-nasal pharynx is filled with a nearly air-equivalent foam. Optional animal lungs, which duplicate the intricate detail of the vascular trees, are available. These lungs are fixed in the inflated state and are molded to conform to the pleural cavities of the phantom. The pulmonary arteries are injected with a blood-equivalent plastic. In addition, low or high contrast material may be selected by the user.

Skeletons  

RSD* polymer skeletons, with trabecular patterns, fit precisely within the soft-tissue molds. The bones of a single individual, who matched PIXY molds very closely, were used in making the RSD skeletal molds. Skeletons have a fixed chemical composition 

(no osteoporosis or contamination). The medullary cavities were reproduced, with only minor simplification, to make molds for the spongiosa, about which the cortical bone is molded. Both cortical bone and spongiosa are radio-equivalent to natural bone. 

Skeletons are in continuous production, so quick shipments are routine. Human skeletons are available, nevertheless, for users who desire them. There is a surcharge to cover the high cost of rarely-available natural skeletons and for added labor for their rework. 

The matching of skeletons and soft-tissues permits external and bony landmarks to coincide. The position of bones within the soft tissues is anatomically correct. 

The detail cast into RSD skeletons is considered a triumph of the sculptural moldmaker's craft. The skull, for example, has frontal and sphenoidal sinuses, ethmoidal and mastoid air cells and the auditory ossicles. Bone sutures are radiographically visible. 

REFURBISHMENT 

RSD offers PIXY refurbishment service which corrects the wear and tear resulting from usage over an extended period of time and restores PIXY to its original condition. This service includes repair of minor bone fractures of hands and feet. Quotes are furnished upon request for more extensive damage.  

* Highly detailed polymer skeletons which reproduce the shape, mass density and attenuation coefficients of the cortical bone and spongiosa, allow continuous production of phantoms instead of sporadic production due to limited availability, variable size and uncertain chemical composition of human skeletons.

NATURAL SKULL: Note the compromises needed to fit a variable skull into a fixed head mold (on right)

 

RSD SKULL: The intricate shape of the skull requires that it be made in four parts, plus the mandible. Manufacturing artifacts have been minimized
