<p><P>PROBLEM TO BE SOLVED: To provide a nuclear medicine diagnosis system which improves temporal resolution and energy resolution, and also improves diagnostic accuracy by heightening moisture-proof and dust-proof effects of a radiation detector while efficiently cooling the radiation detector. <P>SOLUTION: Both a first region A for housing the radiation detector 21 via a heat insulating member 7, and a second region B for housing a signal processing device are provided for the inside of a housing member 5. The housing member 5 is provided with a ventilation hole 8, which is provided with a dust-proof filter 9, in such a way as to communicate with the first region A, and also provided with: a ventilation hole 34 to be an inlet of cooling air; and a unit fan 33 to be its outlet in such a way as to communicate with the second region B. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
