Radiation Therapy Phantom

Full Body Imaging Phantom

The male ART represents a male standing at 175 cm (5 ft 9 in) tall and weighing 73.5 kg (162 lb).

The female ART represents a female standing at 155 cm (5 ft 1 in) tall and weighing 50 kg (110 lb) .

The ART Phantom is transected horizontally into 2.5 cm thick slices. Each slice has holes which are plugged with material equivalent to bone, soft tissue or lung tissue, which can be replaced by TLD holder pins (available separately). 

Soft tissue 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 3 x 3 cm or 1.5 x 1.5 cm in 5 and 7 mm diameters, thereby allowing for detailed measurements of dose distributions.

There are unlimited, small variations in density and absorption throughout the human body. The ART Phantom's soft tissue is closely controlled to have the average density of these tissues.

RSD skeletons are highly detailed polymer mouldings which reproduce the shape, mass density and attenuation coefficients of cortical bone and spongiosa. This allows for continuous production of phantoms, instead of the sporadic production required by the limited availability, variable size and uncertain chemical composition of human skeletons. Our proprietary mouldings allow for continuous production, eliminate the restrictions of human skeleton bones (including limited availability, variable size, and uncertain chemical composition), and avoid the loss of marrows in dried natural skeletons thereby making RSD skeletons superior to “real bone.”

Moulds for the RSD cortical bone and spongiosa were made from human skeletons consistent with the sizes of the soft tissue moulds.

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 are moulded from syntactic foam with a specific gravity of 0.30 g/cc.

Breasts are available in various sizes. They can be sliced in frontal planes, drilled or undrilled for film dosimetry. Breasts for male and female ART Phantoms are contoured to blend realistically with the thoraxes and attached with nylon screws. The male chest with attached breasts serves as a large female.
