Abstract
Abstract An exemplary embodiment includes a patient support, a radiation measuring arrangement comprised of a radiation source which generates a fan-shaped radiation beam penetrating the radiography subject and disposed transversely to the patient support, and a radiation receiver having an array of detectors. A predetermined body region is scanned by the measuring arrangement, and, via a measurand processing circuit, an image of the scanned body region is formed. The radiation receiver is pivotally mounted about an axis disposed perpendicularly to the radiation beam.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A diagnostic radiology installation comprising a patient support, a radiation measuring arrangement comprised of a radiation source, which generates a fan-shaped radiation beam lying in a fan-plane and penetrating the radiography subject, and of a radiation receiver having an array of detectors, means for producing a relative movement between the patient support and the radiation measuring arrangement, and a measurand processing circuit for the formation of an image of the body region scanned during the relative movement, the improvement comprising said radiation receiver being pivotally mounted for pivotal movement about a pivot axis extending perpendicularly to the fan-plane of the radiation beam, said radiation receiver being pivotally movable relative to the radiation beam so as to adjust the resolution of the radiation receiver.
Claim 2
Dependent Claim
123 words
A diagnostic radiology installation comprising a patient support, a radiation measuring arrangement comprised of a radiation source, which generates a fan-shaped radiation beam lying in a fan-plane and penetrating the radiography subject, and of a radiation receiver having an array of detectors, means for producing a relative movement between the patient support and the radiation measuring arrangement, and a measurand processing circuit for the formation of an image of the body region scanned during the relative movement, the improvement comprising said radiation receiver being pivotally mounted for pivotal movement about a pivot axis extending perpendicularly to the fan-plane of the radiation beam, said radiation receiver being pivotally movable relative to the radiation beam so as to adjust the resolution of the radiation receiver.
Claim 3
Dependent Claim
28 words
A diagnostic radiology installation according to claim 1, with said radiation receiver being pivotally mounted such that the pivot axis extends through the center of the radiation receiver.
Claim 4
Dependent Claim
21 words
A diagnostic radiology installation according to claim 2, with the radiation receiver being pivotal as a unit about the pivot axis.
Claim 5
Dependent Claim
28 words
A diagnostic radiology installation according to claim 2, with the radiation receiver comprising two halves which, at their mutually facing ends, are pivotally mounted about the pivot axis.
Claim 6
Dependent Claim
148 words
A diagnostic radiology installation comprising a patient support, a radiation measuring arrangement comprised of a radiation source which generates a fan-shaped radiation beam penetrating the radiography subject, and a radiation receiver having an array of detectors, means for producing a relative movement between the patient support and the radiation measuring arrangement, and a measurand processing circuit for the formation of an image of the body region scanned during the relative movement, the improvement comprising the radiation receiver having a plurality of parts, each of which is pivotally mounted about an individual pivot axis disposed perpendicularly to the fan-plane of the radiation beam, the individual pivot axes of the respective parts being offset from each other, and the respective parts of the radiation receiver being pivotally movable relative to respective portions of the radiation beam so as to adjust the resolution of the respective parts of the radiation receiver.
Claim 7
Dependent Claim
