Abstract
Abstract An X-ray examination apparatus comprising: a base assembly including a pivotable and vertically displaceable frame, a first actuating means for pivotal movement of said frame about a horizontal axis and a second actuating means for vertical movement of said frame, computer controls for controlling said first and second actuating means individually and in combination, two parallel rail systems supported by the frame and having two carriages mounted respectively thereon, which carriages can move in unison or individually, one of said carriages supporting a C- or U-shaped carriage for supporting an X-ray source and image receptor in a rotatable arrangement about an axis parallel to said horizontal axis and the other of said carriage having an overhanging support secured thereto, which support includes a dual action mechanism for supporting a patient table in an arrangement providing its vertical movement relative to the frame and its pivoting movement about an axis parallel to its longitudinal axis.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
219 words
An X-ray examination apparatus comprising in combination: a telescoping vertical support member extending from and supported by a base; a pivotable structure including a semicircular planar member disposed in a vertical plane and supported by said telescoping vertical support in a pivotable arrangement about an axis passing through the center of the radius of said semicircular planar member and parallel to a first horizontal direction, and wherein said semicircular planar member supports two parallel rail systems extending in a second horizontal direction generally parallel to said first horizontal direction; a first and a second support members mounted repectively on said parallel rail systems in a slidable arrangement in the second horizontal direction, and wherein said first and said second support members at their respective outwardly positions at least partly overhang opposite extremities of said semicircular planar member and wherein their respective ranges of travel extend at least partly into each other; a carriage for supporting an X-ray source and an X-ray image receptor supported by an elongated member disposed in the first horizontal direction and supported by the second support member in a slidable arrangement in said first horizontal direction; a patient table disposed intermediate said X-ray source and said X-ray image receptor and supported in an overhanging arrangement by a supporting structure secured to said first support member.
Claim 2
Dependent Claim
219 words
An X-ray examination apparatus comprising in combination: a telescoping vertical support member extending from and supported by a base; a pivotable structure including a semicircular planar member disposed in a vertical plane and supported by said telescoping vertical support in a pivotable arrangement about an axis passing through the center of the radius of said semicircular planar member and parallel to a first horizontal direction, and wherein said semicircular planar member supports two parallel rail systems extending in a second horizontal direction generally parallel to said first horizontal direction; a first and a second support members mounted repectively on said parallel rail systems in a slidable arrangement in the second horizontal direction, and wherein said first and said second support members at their respective outwardly positions at least partly overhang opposite extremities of said semicircular planar member and wherein their respective ranges of travel extend at least partly into each other; a carriage for supporting an X-ray source and an X-ray image receptor supported by an elongated member disposed in the first horizontal direction and supported by the second support member in a slidable arrangement in said first horizontal direction; a patient table disposed intermediate said X-ray source and said X-ray image receptor and supported in an overhanging arrangement by a supporting structure secured to said first support member.
Claim 3
Dependent Claim
50 words
A system according to claim 1 further including a first actuating means for vertical displacement of said telescoping vertical support member and a second actuating means for pivoting movement of said pivotable structure, a computer control means for controlling said first and said second actuating means individually and in combination.
Claim 4
Dependent Claim
41 words
An apparatus according to claim 1 wherein said semicircular planar member at least in part has a timing belt disposed therealong and secured thereto, wherein said timing belt is engaged by at least one timing wheel driven by a drive member.
Claim 5
Dependent Claim
16 words
An apparatus according to claim 3 wherein said first actuating means includes a ball screw actuator.
Claim 6
Dependent Claim
28 words
An system according to claim 1 wherein said carriage is rotatably supported by said elongated member about an axis parallel to the longitudinal axis of said elongated member.
Claim 7
Dependent Claim
18 words
A combination as set forth in claim 5 wherein said X-ray image receptor includes a spot film device.
Claim 8
Dependent Claim
114 words
An X-ray table assembly comprising in combination: a patient table supported by an overhanging support structure extending from and secured to a support means, said overhanging support structure comprising: a bracket supporting said patient table, an elongated member with one extremity pivotably secured to said support means and the other extremity pivotably secured to said bracket; a first elongated actuator member with one extremity pivotably secured to said support means and the other extremity pivotable secured to said bracket, a second elongated actuator member with one extremity pivotably secured to said support means and the other extremity pivotably secured to said elongated member disposed in an angled relationship to said first elongated actuator member.
Claim 9
Dependent Claim
114 words
An X-ray table assembly comprising in combination: a patient table supported by an overhanging support structure extending from and secured to a support means, said overhanging support structure comprising: a bracket supporting said patient table, an elongated member with one extremity pivotably secured to said support means and the other extremity pivotably secured to said bracket; a first elongated actuator member with one extremity pivotably secured to said support means and the other extremity pivotable secured to said bracket, a second elongated actuator member with one extremity pivotably secured to said support means and the other extremity pivotably secured to said elongated member disposed in an angled relationship to said first elongated actuator member.
