Radiological imaging apparatus and its cooling system

A radiological imaging apparatus comprising:

• a bed which supports an object to be examined;
• and
• an imaging apparatus,
• wherein said imaging apparatus has unit substrates each comprising a first substrate including a radiation detector and a second substrate including a signal processing apparatus to which detection signals of said radiation detector are inputted and being coupled with said first substrate through a connector, and
• said imaging apparatus is provided with a heat insulating member of separating mutually a first area where said radiation detectors are disposed from a second area where said signal processing apparatuses are disposed, both of which are formed inside said imaging apparatus.

A cooling method of a radiological imaging apparatus comprising a bed which supports an object to be examined and an imaging apparatus,

• said imaging apparatus having an annular support member surrounding said bed, a plurality of detector units attached to the above described support member and a cooling apparatus;
• said detector unit being provided inside a housing member with a plurality of unit substrates including a plurality of radiation detectors and signal processing apparatuses to which detection signals of said radiation detectors are inputted;
• a cooling apparatus having a first coolant path which is formed inward from said support member and inside said imaging apparatus and a second coolant path, which is formed outward from said support member and inside said imaging apparatus;
• a heat insulating member provided inside said housing member separating a first area where said radiation detectors are disposed from a second area where said signal processing apparatuses are disposed;
• and
• a part of said first area of said detector unit being disposed inside said first coolant path and a part of said second area of said detector unit being disposed inside said second coolant path, said cooling method comprising the steps of:
• supplying coolant to said first coolant path;
• and
• supplying said coolant inside said first coolant path to said second coolant path.
