    • A mammography system in which the peripheral portion of the mammo-area (Ma) in the chest of a subject (M) abuts against a chest abutting box (3) during photography of RI distribution image at the mammo-area (Ma) of the subject (M), and since body motion incident to breathing of the subject (M) moves from the chest side to the back side, movement of the mammo-area (Ma) of the subject (M) incident to breathing of the subject (M) can be suppressed with no strain. Furthermore, since photography of the RI distribution image is performed in a seated posture where the subject (M) is sitting on a sitting portion (2), the system becomes compact as compared with a case where photography of the RI distribution image is performed in a sleeping posture where the subject (M) is lying on one's back or on one's side on a top plate, and thereby it can be installed even in a limited space.

    • PURPOSE: A multilayer flat type detector and a 3D location detecting method for measuring gamma-ray image are provided to use for a gamma-ray image detector essential for environment monitoring and nuclear medicine imaging. CONSTITUTION: A multilayer flat type detector for measuring gamma-ray image comprises a first multilayer block type flash crystal(10), and a 2-dimensional photo sensor(30). The first multilayer block type flash crystal comprises a 2-dimensional block type flash crystal(11) and 2-dimensional block type optical glass layers(12,13). The 2-dimensional photo sensor senses an optical signal. The first multilayer block type flash crystal and 2-dimensional photo sensor are optically combined. A detector module sets up a 3D index table using the first multilayer block type flash crystal. The multilayer block type flash crystal is composed of a flash crystal which can obtain experimental location information on 3D gamma-ray reaction.
