US 5,857,007 A · DAS housing with enhanced heat transfer capability for CT imaging system

Abstract

In a CT imaging system which includes a gantry having a rotatable ring member and a DAS comprising circuit boards grouped in a selected number of sets, a DAS housing is provided which is disposed to dissipate heat away from the DAS circuit boards. The housing includes a frame for mounting each of the circuit boards on the gantry ring so that the boards of a set are in spaced-apart relationship with each other, and further includes a cover for each frame, to form an enclosure for the circuit boards supported thereby. Each cover is provided with a panel member, a section of each panel being provided with a specified pattern of perforations. Each panel is positioned with respect to its set of circuit boards to provide an unobstructed space of selected dimension between its pattern of perforations and its corresponding circuit board set.

Dependent claims

In a CT imaging system which includes a gantry having a rotatable ring member and further includes a data acquisition system comprising circuit boards grouped in a selected number of sets, a housing for the data acquisition system comprising:

means for mounting each of said circuit boards on said rotatable ring member so that the boards of a set are in spaced-apart relationship with each other;
a panel corresponding to each of said circuit board sets, a section of each panel being provided with a specified pattern of perforations;
means for attaching each of said panels to said mounting means so that each panel is in fixed relationship with the circuit boards of its corresponding set, a given one of said panels being positioned to provide an unobstructed space of selected dimension between its pattern of perforations and its respective corresponding circuit boards;
and
said data acquisition system comprises a plurality of circuit board sets, which are mounted on said ring member in adjacent relationship.

Apparatus for a CT imaging system which includes a gantry having a rotatable member, and further includes a data acquisition system comprising circuit boards grouped in a selected number of sets, said apparatus comprising:

a gantry shielding structure positioned to form a gantry enclosure around said gantry;
means for mounting each of said circuit boards on said rotatable gantry member so that the boards of a set are in spaced-apart relationship with each other;
a panel corresponding to each of said circuit board sets;
means for attaching each of said panels to said mounting means so that each panel is in fixed relationship with the circuit boards of its corresponding set, said attaching means, said mounting means, and said panels collectively forming a data acquisition system enclosure which is positioned around said data acquisition system, and is located within said gantry enclosure;
and
each of said panels has a section provided with an array of closely spaced perforations formed therethrough to enable substantially unrestricted airflow between said data acquisition system enclosure and said gantry enclosure, the perforation array formed through the section of a given one of said panels defining a selected geometric pattern which substantially covers the area of said section of said given panel.
