IPC: A61B5/0275
Filed: 2001-03-06
Abstract: PROBLEM TO BE SOLVED: To measure with good precision the radioactivity of a radioactive reagent administered to a subject. SOLUTION: A pre-dose sample is taken from a subject before administration of a radioactive reagent, subsequently the radioactive reagent is administered, and a post-dose sample is taken. The radiation from the pre-dose and post-dose samples is counted at the same time using radiation detectors 2 and 4.

The normalized counting value NBG for the pre-dose sample corresponds to the contributing part of background radiation contained in the normalized counting value NS for the post-dose sample. A subtracter 34 removes the influence of background radiation by calculating (NBG-NS) and determines a counting value attributed to the radioactive reagent contained in the post-dose sample.  In addition, a reagent concentration operation part 36 calculates the concentration of the radioactive reagent in the samples.
