DOSIMETRY VERIFICATION PHANTOMS

ATOM Phantoms

Standard phantoms include bone, lung and soft tissue compositions formulated for accurate simulation for diagnostic and therapy energies.
Photon attenuation values between 30 KEV and 20 MEV are within 1% for bone and soft tissue substitutes and within 3% for lung substitute.
The skeleton is made from an average composition of normal cortical and trabecular bone and includes vertebral disks and spinal cord.
Standard phantoms consist of 25mm thick contiguous sections.
Each section contains 5mm diameter through holes and tissue equivalent plugs for TLD placement. Hole locations are optimised for precise dosimetry in 19 internal organs (detailed list available upon request). Ion chamber cavities, other grid patterns and hole diameters are available upon request.

Standard phantom includes head, torso, upper femur and genitalia.
Legs and arms are included with the newborn and 1 year paediatric phantoms. Legs and arms can be manufactured for other phantoms upon special request.

All phantoms include detailed technical manual, positioning system and storage case. Attenuation coefficients for all materials is available upon request.

RANDO PHANTOM
REAL BONE MAN OR WOMAN

The RANDO® Phantoms provide the detailed mapping of dose distribution that is essential for evaluating radiotherapy treatment plans. There are two RANDO® models, RANDO® Man and RANDO® Woman. Breast accessories are available for both models.

Like the Sectional Phantoms, the RANDO® Phantoms are constructed with a natural human skeleton cast inside material that is radiologically equivalent to soft tissue. The RANDO® lungs are molded to fit the contours of the natural human rib cage. The lower-density material in the RANDO® lungs is designed to simulate human lungs in a median respiratory state.

Includes clamping base and permanent storage case.

ART PHANTOM
MIMICK BONE MAN OR WOMAN

The Alderson Radiation Therapy phantom (ART) and its earlier version, the Alderson RANDO phantom, have been in use for over 30 years. The ART has been refined and improved in both design and materials. These phantoms are indispensable quality-assurance tools; more than 2,000 are in use all over the world. They provide integrated tests of the entire chain of treatment planning and delivery.

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 male ART represents a 175 cm (5 ft. 9 in.) tall, 73.5 kg (162 lb) male, and 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 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 3 cm x 3 cm or 1.5 cm x 1.5 cm in 5 and 7 mm diameters. These afford detailed measurements of dose distributions.
