Individual X-Rays
Individual X-Rays for each Doll

• Each Doll is individually X-rayed
• Customers can be reassured that there are no metal parts in the Doll by referring to the set of digital X-
• Rays which are supplied with each Doll
• Images shown were taken using medium frequency generator; no grid; fine focus; 100cm S.I.D. Fuji CR system

Positioning and CT Scanning
Positioning

• The Doll is best used in the recumbent positions as, although it is possible to use an upright bucky with supports, this makes the use of positioning blocks and immobilization devices more difficult
• The Doll will lie naturally in the neutral position, prone or supine, without support
• A wide selection of positioning aids must be at hand, e.g. foam blocks, wedges, sand bags and compression band. These are essential to maintain any position other than neutral as the skin of the Doll has some resistance to overcome. This is, of course, an advantage in the teaching as it prevents the student cutting corners by omitting the use of these positioning aids
  
• The Doll can be positioned for all standard projections with no more difficulty than a difficult patient might present.

CT Scanning

• The X-Ray Positioning Doll was positioned and imaged for a whole body CT (Computed Tomography) investigation
• Good images in terms of body outline and fundamental structure can be obtained
• Certain areas of the skeleton structure e.g. thoracic vertebrae and the head of the femur gave similar values to the typical patient
• As the doll is very different from the human body in terms of attenuation, it cannot be used for training in, or practising exposure control
