Abstract:
1. A nuclear medicine diagnosis device for obtaining nuclear medicine data on a subject injected with a radiopharmaceutical based on radiant rays generated from the subject, comprising: a radiation detection unit configured to contain an element emitting a plurality of radiant rays simultaneously; a blank data collection unit collecting coincidence count data as blank data, the coincidence count data being coincidentally counted by causing the radiation detection unit configured to contain the element to count some of the radiant rays emitted from the element contained in the radiation detection unit and causing another radiation detection unit to count other radiant rays in a state in which the subject is absent; a transmission data collection unit collecting coincident count data as transmission data, the coincidence count data being coincidentally counted by causing the radiation detection unit configured to contain the element to count some of the radiant rays emitted from the element contained in the radiation detection unit and another radiation detection unit to count other radiant rays in a state in which the subject is present; an emission data collection unit collecting coincidence count data as emission data, the coincidence count data being coincidentally counted by causing the radiation detection unit to count the radiant rays generated from the subject injected with the radiopharmaceutical; an absorption-corrected data calculation unit calculating absorption-corrected data on the subject based on at least one of the blank data collected by the blank data collection unit and the transmission data collected by the transmission data collection unit; and an absorption correction unit absorption-correcting the emission data collected by the emission data collection unit using the absorption-corrected data, and finally obtaining the absorption-corrected emission data as the nuclear medicine data.
