General Information
1.1 Introduction
These phantoms can be used with any computed tomography (CT) system designed to image both head
and body. They can separate dose information for each. When performing dose profile measurements,
the dose phantoms allow the user to collect information for the maximum, minimum and mid-range value
of the nominal tomographic section thickness.
This essential phantom consists of two parts: a body phantom and a head phantom. Both are made of
solid acrylic, 15 cm thick, with diameters of 32 cm and 16 cm, respectively. Each part contains five probe
holes, one in the center and four around the perimeter, 90° apart and 1 cm from the edge. The inside
diameter of the holes is 1.31 cm. Each part includes five acrylic rods for plugging all the holes in the
phantom. A storage and carrying case is available as an option.
1.2 Applications
The CT Dose Phantoms were designed in accordance with the Food and Drug Administration's
performance standard for diagnostic x-ray systems, which includes regulations specifically applicable to
CT systems (21 CFR 1020.33).
