ART phantoms are molded of tissue-equivalent material, they are designed within highly sophisticated technological constraints and follow ICRU-44 standards. They are also designed for accuracy and ease of use.
Features and Benefits
- Anatomy
- The Female ART represents a 155 cm (5 ft. 1 in.) tall, 50 kg (110 lb.) female.
- The ART phantom is transected-horizontally into 2.5 cm thick slices.
- Each slice has holes which are plugged with bone-equivalent, soft-tissue-equivalent or lung tissue equivalent pins which can be replaced by TLD holder pins.
- Soft-tissue-equivalent coatings produce slices with glass smooth interfaces.
- These coatings are cut away over the air spaces of the oronasal pharynges, trachea and stem bronchi.
- Dosimetry holes are drilled in grids 3cm x3 cm or 1.5cm x 1.5cm in 5 and 7 mm diameters.
- Breast Attachments
- They can be sliced in frontal planes (drilled or undrilled for film dosimetry).
- Slices can receive any of the pins listed below.
- Breasts of male and female ART phantoms are contoured to blend realistically with the thoraxes.
- They are attached to the thorax with nylon screws.
- The male chest with breasts attached serves as a large female.
- Materials
- Soft Tissues
- There are unlimited, small variations in density and absorption throughout the human body.
- Phantom soft tissue is closely controlled to have the average density of these tissues.
- Skeletons
- RSD skeletons are highly-detailed polymer moldings which reproduce the shape, mass density and attenuation coefficients of cortical bone and spongiosa.
- They allow continuous production of phantoms, instead of the sporadic production required by the limited availability, variable size and uncertain chemical composition of human skeletons.
- These problems, plus loss of marrows in dried natural skeletons, make RSD skeletons superior to ‘real bone’.
- Molds for the RSD cortical bone and spongiosa were made from human skeletons consistent with the sizes of the soft tissue molds.
- RSD skeletons conform closely to the standards established by the International Commission on Radiation Units and Measurements (ICRU Report No. 44), mass density is reduced slightly to take into account a small decrease in calcium content for older patients.
- Lungs
- Lungs are molded from syntactic foam, with a specific gravity of 0.30 g/cc.
- Assembly
- ART phantom slices are held between aluminum plates by nylon tie rods.
- Knobs at the end of the rods clamp the slices tightly in proper alignment.
- The external assembly facilitates film dosimetry, while the internal assembly is used generally with TLDs or ionchamber dosimetry.
