Abstract
Abstract An effective ray beam includes an arc-shaped cut-out element having its open side facing in the direction toward the center of a ray beam. Via a variable arrangement of the arc-shaped cut-out element in a plane perpendicular to the ray beam, the effective ray beam can be individually adjusted to an arc-shaped object under examination.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
Radio diagnostic equipment for radiographic mamma diagnostics having an adjusting arrangement arranged in the ray path of an X-ray source which has an adjustable element, one side of the adjustable element being arranged in a direction towards the effective ray beam for adjusting the effective ray beam emitted by the X-ray source, wherein: said adjustable element is essentially cylinder-shaped and rotatably supported around its longitudinal axis with an arc-shaped cut-out extending from said one side unsymmetrically with respect to its axis of rotation, so that the effective ray beam is able to be adjusted so as to have an arc-shape which is similar to an arc-shaped examination object.
Claim 2
Dependent Claim
108 words
Radio diagnostic equipment for radiographic mamma diagnostics having an adjusting arrangement arranged in the ray path of an X-ray source which has an adjustable element, one side of the adjustable element being arranged in a direction towards the effective ray beam for adjusting the effective ray beam emitted by the X-ray source, wherein: said adjustable element is essentially cylinder-shaped and rotatably supported around its longitudinal axis with an arc-shaped cut-out extending from said one side unsymmetrically with respect to its axis of rotation, so that the effective ray beam is able to be adjusted so as to have an arc-shape which is similar to an arc-shaped examination object.
Claim 3
Dependent Claim
36 words
Apparatus according to claim 1, wherein said arc-shaped cut-out extends symmetrically with respect to a plane perpendicular to its axis of rotation and which is in the direction of the center of the effective ray beam.
Claim 4
Dependent Claim
39 words
Apparatus according to claim 1, wherein said adjusting arrangement is arranged on the side of the X-ray source housing which faces the examination object and is slidably supported in a plane perpendicular to the center of the ray beam.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 1, wherein said cylindrical-shaped element is slidably supported in its axial direction.
Claim 6
Dependent Claim
19 words
Apparatus according to claim 1, wherein said adjusting arrangement is rotatably mounted around the center of the ray beam.
Claim 7
Dependent Claim
22 words
Apparatus according to claim 1, wherein said adjusting arrangement is rotatably mounted around a parallel to the center of the ray beam.
