Description

EVALUATION OF DETECTABILITY, EXTENT, AND SEVERITY OF MYOCARDIAL INFARCTS IN PATIENTS

The thorax is mounted on a base plate with an O-ring seal. Four rubber feet provide space under the phantom for drain fittings the base plate is removed readily to provide access to the interior of the phantom.

Specifications

The thorax is molded of polyurethane, modified for tissue equivalence, with a mass density of 1.10 g/cc. The narrow beam linear attenuation coefficient measured at 140 keV (Tc-99m) is 0.160 cm -1.

The RSD materials closely meet the standards of the International Commission on Radiation Units and Measurement (ICRU) Report No. 44 (Tissue Substitutes in Radiation Dosimetry and Measurement, 1989) for both the cortical and spongiosa components of the human skeleton. The mass densities are 1.88 g/cc for cortical bone and 1.16 g/cc for spongiosa. The narrow beam linear attenuation coefficient for the cortical component, measured at 140 keV, is 0.280 cm-1.

The volume of each vacuum-formed breast is 972 ml. A tumor, filled with a radioactive solution can be inserted to evaluate the planar and tomographic imaging techniques used for mammoscintigraphy-(2). A set of breast tumors (3, 6, 9, 12 and 15mm diameters) is included. They are supported by thin, threaded nylon rods which pass through ports and are sealed by O-rings. They can be bent by hand to reach any part of a breast.
