Abstract
Abstract The invention relates to an X-ray examination apparatus in which the X-ray source and the X-ray detector are secured to a C-shaped or U-shaped support. This support comprises two arms which are pivotable about parallel axes and which are coupled to one another in such a way that opposite pivotal movements through equal angles are obtained. The C-shape or the U-shape of the support is then changed, so that the support can be rotated without the risk of a collision with the table top carrying the patient.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
An X-ray examination apparatus comprising: a C-shaped or U-shaped support having first and second opposite ends, said support being pivotable about a first axis; an X-ray source arranged on the first end of the support; and an X-ray detector arranged on the second end of the support opposite the X-ray source, a connecting line between the source and the detector being perpendicular to the first axis; characterized in that: the support comprises first and second arms, the X-ray source being mounted on the first arm and the X-ray detector being mounted on the second arm, each arm being pivotable about a pivot axis which is substantially parallel to the connecting line; and the support comprises means for coupling the first arm to the second arm such that when one arm is pivoted in a first direction, the other arm is pivoted with an equal angular velocity in the opposite direction.
Claim 2
Dependent Claim
150 words
An X-ray examination apparatus comprising: a C-shaped or U-shaped support having first and second opposite ends, said support being pivotable about a first axis; an X-ray source arranged on the first end of the support; and an X-ray detector arranged on the second end of the support opposite the X-ray source, a connecting line between the source and the detector being perpendicular to the first axis; characterized in that: the support comprises first and second arms, the X-ray source being mounted on the first arm and the X-ray detector being mounted on the second arm, each arm being pivotable about a pivot axis which is substantially parallel to the connecting line; and the support comprises means for coupling the first arm to the second arm such that when one arm is pivoted in a first direction, the other arm is pivoted with an equal angular velocity in the opposite direction.
Claim 3
Dependent Claim
29 words
An X-ray examination apparatus as claimed in claim 1, characterized in that when the pivot axes are horizontal, their moments of the arms are equal but opposite in direction.
Claim 4
Dependent Claim
21 words
An X-ray examination apparatus as claimed in claim 2, characterized in that the coupling means comprises two gears of equal diameters.
Claim 5
Dependent Claim
40 words
An X-ray examination apparatus as claimed in claim 3, characterized in that the X-ray source is rotatably connected to the end of the first arm, the X-ray source being rotatable about an axis which is perpendicular to the pivot axis.
Claim 6
Dependent Claim
21 words
An X-ray examination apparatus as claimed in claim 1, characterized in that the coupling means comprises two gears of equal diameters.
Claim 7
Dependent Claim
40 words
An X-ray examination apparatus as claimed in claim 5, characterized in that the X-ray source is rotatably connected to the end of the first arm, the X-ray source being rotatable about an axis which is perpendicular to the pivot axis.
