American RSD phantom ART-200X Alderson radiotherapy model phantom

Overview

American RSD phantom ART-200X Alderson radiotherapy model phantomChoose between male or female.

The Alderson Radiotherapy Model (ART) and its earlier version, the Alderson RANDO Model, have been used for more than 30 years. ART has made improvements and improvements in both design and materials. These phantoms are quality assurance tools; used by approximately 10,000 people. They offer comprehensive testing of the entire treatment plan and delivery chain.

ART phantoms are molded from tissue-equivalent materials; they are designed under highly complex technical constraints and adhere to ICRU-44 standards. They are also designed for accuracy and ease of use. A big woman.

Anatomy

maleART stands for 175 centimeters (5 feet 9 inches) tall and 73.5 kilograms (162 pounds) for men, and ART stands for 155 centimeters (5 feet 1 inch) tall and 50 kilograms (110 pounds) for women.

Features

1. Cut the ART phantom crosswise and horizontally into 2.5 cm thick slices. Each slice has holes for insertion of soft tissue equivalents of bone or lung tissue equivalent needles, which can be replaced by TLD fixation pins. Bracket pins are ordered separately.

2. Molded from tissue-equivalent materials; they are designed under highly complex technical constraints and comply with ICRU-44 standards. Research topics related to radiation protection and radiation accident dosimetry research require models that simulate the human body for experimental research and measurement of simulated measurement of whole-body dose and organ dose. It is also needed to conduct confirmatory experimental research in the study of dosimetry theoretical estimation systems, especially computer estimation systems.

3. The phantom is layered into 35 layers (32 layers for women), and the human bones are cast in soft tissue equivalent materials. The lungs are cast to fit the contours of the ribs. The air gaps in the head, neck and trunk bronchi are the same as those of a real person. The phantom is cut into pieces, each piece is 2.5cm thick, and film can be placed between the pieces. There is a grid of holes on the chip, which can be used as a thermoluminescence detector.

4. Soft tissue: There are infinite small changes in the density and absorption of the human body. The soft tissues of the phantom are closely controlled to obtain an average density of these tissues.

5. Bones: The bones meet the standards of ICRU No. 44 report. Made of polymer, taking into account the different mass densities and attenuation coefficients of cortical and cancellous bone. Cortical and cancellous casts are made from human bone and conform to the dimensions of soft tissue. Taking into account the decrease in calcium content in the elderly.

6. Lungs: The lungs are made of syntactic foam casting material with a specific gravity of 0.30g/cc.

7. Mold body piece: placed between aluminum plates by using nylon steering tie rods. The button at the end of the wand clamps the phantom piece tightly and in the same axis. The plate adjusts the inner and outer rods and can therefore support many phantoms。

Soft tissue equivalent coating produces slices with a glass-smooth interface. These coatings are excised in the spaces between the oronasopharynx, trachea and stoma bronchus. The dosimetry hole is3cm x 3cm or 1.5cm x 1.5cm 5 and 7mm diameter grid drilling holes. These provide detailed measurements of dose distribution.

Breasts are available in a variety of sizes. They can be sectioned in the frontal plane (drilled or undrilled for film dosimetry). Slices can receive any of the pins listed below. male and femaleThe breast contour of the ART phantom blends realistically with the chest. Secure them to the chest with nylon screws. Male boobs are connected with breasts as a large female.

Material

Soft Tissue: The human body has infinitesimal small variations in density and absorption. The soft tissues of the phantom are closely controlled to obtain an average density of these tissues.

Skeleton: RSD skeletons are highly detailed polymer moldings that reproduce the shape, mass density and attenuation coefficients of cortical bone and spongy body. They allow continuous production of phantoms rather than the sporadic production required due to the limited availability, variable dimensions and uncertain chemical composition of the human skeleton. These issues, coupled with the loss of bone marrow in natural dry skeletons, make RSD bones superior to "real bones."

used forRSD cortical bone and spongy body molds are made from human bone and are consistent in size with soft tissue molds.

The RSD skeleton complies with the standards set by the International Commission on Radiation Units and Measurements (ICRU Report No. 44); the mass density is slightly reduced to take into account the slight decrease in calcium content in elderly patients.

Lungs: Lungs are shaped from composite foam with a specific gravity of0.30 g/cm3.

TLD DOSIMETERS & ACCESSORIES

All dose test holes are equipped with blank pins.The pins of the TLD chip have a recess of 3.2×3.2×0.9 mm at one end. The pins for the TLD rods have 1 mm diameter holes cross-drilled in the center of the pins. Unless otherwise noted, all pins are 2.50 cm long.
