<P>PROBLEM TO BE SOLVED: To provide a nuclear medicine diagnosis device capable of simply determining a depth of an organ of a subject. <P>SOLUTION: The nuclear medicine diagnosis device has detection means, control means and calculation means. The detection means has a collimator. The collimator selects radiation emitted from an organ of a subject to which a radioactive isotope is administered. The detection means detects the radiation passed through the collimator. The control means makes the detection means detect a first image of the organ and a second image of the organ with different sizes. The calculation means calculates the sizes of the first image and the second image, and determines a distance from the organ to a body surface of the subject based on the difference between the size of the first image and the size of the second image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
