Design and Properties of the Whole Body Scanner at Duke¹

ABSTRACT

The whole body scanner described measures retention and distribution of radioisotopes in vivo. The values derived by computer analysis are expressed in fractions of the administered dose. A visual presentation of distribution is provided by the computer in the form of a radioactivity contour map that permits the detection and localization of concentrations of radioactive material. The instrument is capable of making measurements of radioisotopes at tracer and therapeutic dose levels. It is helpful in clinical investigations and it may enable us to improve the dosimetry of internal radiation.
