Abstract

Abstract An x-ray examination apparatus has a bent carrier having a first end to which a radiation source is attached and a second end to which an x-ray image intensifier is connected. The radiation source and the image intensifier are respectively connected to the carrier via individual, laterally projecting booms. Each boom is connected to the carrier so as to be rotatable around an axis at the end of the carrier to which it is connected. The arrangement allows unimpacted accessibility to the patient in different types of examinations.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 112 words
An x-ray examination apparatus comprising: a bent carrier having first and second ends, and means for supporting said carrier in an examination room; a first boom mounted to laterally project from said carrier at said first end of said carrier, said first boom being rotatable around a first axis at said first end of said carrier; an x-ray source mounted to said first boom; a second boom mounted at said second end of said carrier to laterally project from said carrier, said second boom being mounted so as to be rotatable around a second axis at said second end of said carrier; and an x-ray image intensifier mounted on said second boom.
Claim 2
Dependent Claim 112 words
An x-ray examination apparatus comprising: a bent carrier having first and second ends, and means for supporting said carrier in an examination room; a first boom mounted to laterally project from said carrier at said first end of said carrier, said first boom being rotatable around a first axis at said first end of said carrier; an x-ray source mounted to said first boom; a second boom mounted at said second end of said carrier to laterally project from said carrier, said second boom being mounted so as to be rotatable around a second axis at said second end of said carrier; and an x-ray image intensifier mounted on said second boom.
Claim 3
Dependent Claim 22 words
An x-ray examination apparatus as claimed in claim 1 wherein said first and second axes are in axial alignment with each other.
Claim 4
Dependent Claim 38 words
An x-ray examination apparatus as claimed in claim 1 wherein said first and second axes are disposed parallel to each other, and wherein movement of said x-ray source and said x-ray image intensifier are controlled by drive mechanisms.
Claim 5
Dependent Claim 71 words
An x-ray examination apparatus as claimed in claim 1 wherein said x-ray source is mounted on said first boom so as to be rotatable around a third axis and wherein said x-ray image intensifier is mounted on said second boom so as to be rotatable around a fourth axis so that said x-ray source and said x-ray image intensifier can be aligned to each other at all positions of said booms.
Claim 6
Dependent Claim 32 words
An x-ray examination apparatus as claimed in claim 4 wherein said x-ray image intensifier and said x-ray source are each rotatable respectively around said third and fourth axes by respective drive mechanisms.
