Couch system for x-ray diagnosis

A couch system for an X-ray diagnosis provided with an X-ray diagnosis apparatus having a C-shaped arm member, comprising:

• a base portion fixed to a floor in an X-ray diagnosis room;
• a movable portion mounted to the base portion to be movable with respect to the base portion and having a table top on which a patient lies, said movable portion having a central longitudinal axis;
• a tilting mechanism secured to the base portion and incorporated therein for vertically tilting substantially an entire structure of the movable portion with respect to the base portion, said tilting mechanism being driven by a first electric means;
• a first moving mechanism for horizontally moving the table top in a longitudinal direction thereof;
• a second moving mechanism for horizontally moving the table top in a lateral direction thereof;
• and
• an elevating mechanism driven by a second electric means for vertically moving the table top in a perpendicular direction thereof,
• wherein said base portion and said tilting mechanism have a thickness in a width direction of the table top smaller than a width of the table top and disposed below the movable portion along a longitudinal direction of the table top within the width of the movable portion and at a distance spaced from said central longitudinal axis thereof so as to provide a space between a substantial portion of the movable portion and the floor in the X-ray diagnosis room in which the C-shaped arm member is freely movable, said substantial portion comprising more than one-half the width and all of the length of the movable portion, and wherein said movable portion is tilted about a central axis which is positioned below a horizontal level of the table top.
