PROBLEM TO BE SOLVED: To broaden a degree of freedom of imaging places for RI distribution imageries so as to implement easily-movable of a unit. SOLUTION: Since, in the unit of the present invention, aγ- ray detector 13 is divided into three parts from a first partialγ-ray detecting element 13A to a third partialγ-ray detecting element 13C and it is possible to convey separately each of the partialγ-ray detecting elements 13A to 13C to the three locations prepared in the vicinity of a test object M so as to arrange in wrap-around the test object M mode, the unit can be easily moved to the other imaging places for RI distribution imageries, compared with conventional cases where theγ- ray detector is arranged in a lump at a gantry. As a result, easily-movable of a unit resulting in broadening of degree of freedom of imaging places for RI distribution imageries. COPYRIGHT: (C)2007,JPO&INPIT
