Female ART Head and Neck (Sections 0-9) with 3cm x 3cm hole grid spacing; either 5mm or 7mm diameter holes, tissue-equivalent plugs. Internal and external assembly systems.
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.
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. The holder pins are ordered separately. 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. These afford detailed measurements of dose distributions.
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.
TLD Dosimeters & Fittings: Phantoms are shipped with all dosimetry holes filled with blank pins. Pins for TLD chips have recesses at one end 3.2 x 3.2 x 0.9 mm. Pins for TLD rods have 1 mm-diameter holes cross-drilled at the centers of the pins. All pins are 2.50 cm long unless otherwise specified.
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. Both internal and external assembly devices are included. The external assembly facilitates film dosimetry, while the internal assembly is used generally with TLDs or ionchamber dosimetry.
