| PIXY® Anthropomorphic Training/Teaching Phantom. |
  | 
PIXY® was designed specifically for training radiologic technologists. PIXY is 5 ft. 1 in. (156cm) tall and weighs 105 lbs. (48kg) She is repeatable, virtually indestructible and a convenient substitute for patients. PIXY is made of tissue-equivalent materals 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 90º to 100º. Hips flex 130º with 30º 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. 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. PIXY MATERIALS Skeletons Skeletons are in continuous production, so prompt shipments are routine. Nevertheless, human skeletons are available for |
| users who desire them. There is a surcharge to cover the high cost of scarce natural skeletons and for added labor
needed to rework them to fit PIXY molds.* 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. * 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. 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 molded of tissue-equivalent foam with the mass density of inflated human lungs (0.30g/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 molded to conform to the pleural cavities of the phantom. The pulmonary arteries are injected with a blood-equivalent plastic. In addition, low, medium or high contrast material may be selected by the user. REFURBISHMENT RSD offers a PIXY refurbishment service which, after wear and tear from usage over an extended period of time, 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. Approximate shipping weights and dims: 265lbs (81" x 32" x 25") RS-102SP are included in the RS-102 |

| Wounded Willy/Damaged Debbie Versions of RSD's PIXY Phantom. |

ANTHROPOMORPHIC RADIOLOGICAL PHANTOMS DIMENSIONS: The size and weight of both Willy and Debbie is a small adult. Since technologists must learn to work with patients of all sizes and weights, a smaller phantom is as valid for training as a larger phantom, and positioning is facilitated. Each is 5 ft., 1" tall (156cm) and weighs 105 lbs. (48 kg). ANATOMY: Willy and Debbie are articulated at the neck, shoulders, elbows, hips and knees. Fractures of the left shoulder and left hip are located in Debbie. To minimize handling problems, all other traumas of the arms and legs are located in Willy and on the right side of Debbie. The articulations provide a broad range of positioning of capabilities, even the "frog position". LUNGS: Lungs are molded of durable materials with radiodensities matched to humans in a median respiratory state. Animal lungs matching the human in size and blood vessels are available, but they are oriented towards research rather than training. SOFT TISSUES: Willy and Debbie have solid "soft tissues" that are hard and rigid. They cannot be palpated to locate traumas. However, radiological technologists are generally informed by the physician as to the views to be taken. |
| SKELETONS: RSD manufactured skeletons are used rather than natural human skeleton. The latter are generally unavailable and usually consist of an assortment of bones ranging from children to adults of ages for which osteoporosis becomes a factor. RSD skeletons are not to be confused with plastic skeletons for teaching anatomy. RSD skeletons are made to fit the soft-tissie molds precisely. They have spongiosa moldings within marrow cavitities and outer, cortical bone. Both constituents meet the internationally-accepted standards for radiodensity and specific gravity. Willy and Debbie Differences: The most obvious difference between them is in the complement of traumas and pathologies assigned to each. Another difference is that Debbie has female breasts, while Willy has natural male chest contours. Debbie is fitted with a wig, while Willy is bald. They are dressed in camo fatigues.
