Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
An x-ray-diagnostics system comprising: means for producing a computed tomography image of an examination subject; means, separate from said means for producing a computed tomography image, for producing fluoroscopic images of said examination subject; a support system for said examination subject shared in common by said means for producing a computed tomography image and said means for producing fluoroscopic images, said support system comprising a base, a guide rail on which said base is movably mounted, and means for moving said base along said guide rail from a first position wherein said examination subject is positioned for producing said computed tomography image and a second position wherein said patient is positioned for producing said fluoroscopic images.
Claim 2
Dependent Claim
116 words
An x-ray-diagnostics system comprising: means for producing a computed tomography image of an examination subject; means, separate from said means for producing a computed tomography image, for producing fluoroscopic images of said examination subject; a support system for said examination subject shared in common by said means for producing a computed tomography image and said means for producing fluoroscopic images, said support system comprising a base, a guide rail on which said base is movably mounted, and means for moving said base along said guide rail from a first position wherein said examination subject is positioned for producing said computed tomography image and a second position wherein said patient is positioned for producing said fluoroscopic images.
Claim 3
Dependent Claim
29 words
An x-ray diagnostics system as claimed in claim 1 for use in an examination room, and wherein said guide rail is disposed at a floor of said examination room.
Claim 4
Dependent Claim
18 words
An x-ray diagnostics system as claimed in claim 2 wherein said guide rail is recessed in said floor.
Claim 5
Dependent Claim
29 words
An x-ray diagnostics system as claimed in claim 1 for use in an examination room, and wherein said guide rail is disposed at a wall of said examination room.
Claim 6
Dependent Claim
29 words
An x-ray diagnostics system as claimed in claim 1 for use in an examination room, and wherein said guide rail is disposed at a ceiling of said examination room.
Claim 7
Dependent Claim
25 words
An x-ray diagnostics system as claimed in claim 1 comprising means for temporarily engaging said support system in said first position or said second position.
Claim 8
Dependent Claim
79 words
An x-ray diagnostics system as claimed in claim 1 wherein said support system includes a support plate having a longitudinal axis, and electromechanical means for adjusting said support plate along said longitudinal axis, wherein said means for producing fluoroscopic images includes an x-ray exposure unit and electromechanical means for spatially adjusting said x-ray exposure unit, and a joystick for controlling respective movements of said support plate and said x-ray exposure unit when said support system in said second position.
Claim 9
Dependent Claim
27 words
An x-ray diagnostics system as claimed in claim 7 wherein said exposure unit is movable in a direction perpendicular to said longitudinal axis of said support plate.
Claim 10
Dependent Claim
49 words
An x-ray diagnostics system as claimed in claim 8 comprising means for adjusting said support plate along said longitudinal axis given a left/right movement of said joystick and for adjusting said x-ray exposure unit along said direction perpendicular to said longitudinal axis given a forward/backward adjustment of said joystick.
Claim 11
Dependent Claim
30 words
An x-ray diagnostics system as claimed in claim 1 wherein said means for producing fluoroscopic images of said examination subject comprises means for producing angiography images of said examination subject.
