<P>PROBLEM TO BE SOLVED: To provide a nuclear medicine diagnosis device suitable for photographing an organ existing at a position decentered from a center of a body cross section, and a SPECT photographing method. <P>SOLUTION: A nuclear medicine diagnosis device for detecting radiation rays emitted from a radioactive isotope administered inside a patient's body and for obtaining image data inside the patient's body is provided with: first and second gamma cameras each including an asymmetric fan beam type collimator which limits the incident direction of the radiation rays and a detector for detecting the radiation rays having passed through the collimator; a rotary ring to which the first and second gamma cameras are attached rotatably around the patient's body axis in such a manner that they are combined by a set angle based on 90 degrees so that the collimators are directed toward an observation object of the patient's body; and a rotation control part for rotating the first and second gamma cameras around the patient's body axis within a preset range. <P>COPYRIGHT: (C)2013,JPO&INPIT |
