Abstract:
    A nuclear medicine diagnostic apparatus is provided that can improve time resolution and energy resolution and diagnosing accuracy by enhancing radiation detectors in terms of moisture-proofing and dust-proofing effects while efficiently cooling the radiation detectors. The apparatus has a first region A in which radiation detectors are to be accommodated, and a second region B in which signal processors are to be accommodated. These regions are provided inside a housing member 5 via an adiabatic member 7 . The housing member 5 also has a ventilation port 8 formed to communicate with the first region A and equipped with an anti-dust filter. Ventilation holes 34 are formed to communicate with the first region B and serving as entrances for cooling air. Unit fans 33 serve as exits for the cooling air.
