Abstract
Abstract The invention is directed to a radiation diaphragm comprising a diaphragm lamella at which adjustment means engage, so that the diaphragm lamella is adjustable in the beam path of a radiation transmitter. Inventively, the diaphragm lamella is composed of an elastic material. The diaphragm lamella can thus be matched to the shape of an examination subject in a simple way.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
43 words
A radiation diaphragm comprising: a diaphragm lamella consisting of flexible material; and adjustment means, engaging said diaphragm lamella, for adjusting the orientation of said diaphragm lamella by flexing said diaphragm lamella for setting a radiation absorption shape selectively matchable to different examination subjects.
Claim 2
Dependent Claim
43 words
A radiation diaphragm comprising: a diaphragm lamella consisting of flexible material; and adjustment means, engaging said diaphragm lamella, for adjusting the orientation of said diaphragm lamella by flexing said diaphragm lamella for setting a radiation absorption shape selectively matchable to different examination subjects.
Claim 3
Dependent Claim
18 words
A radiation diaphragm as claimed in claim 1 wherein said diaphragm lamella is composed of an elastic material.
Claim 4
Dependent Claim
53 words
A radiation diaphragm as claimed in claim 1 for use with an x-ray beam having a central ray, and wherein said diaphragm lamella has an axis disposed perpendicularly relative to said central ray, and wherein said adjustment means comprises means for engaging said diaphragm lamella for adjusting said diaphragm lamella around said axis.
Claim 5
Dependent Claim
68 words
A radiation diaphragm as claimed in claim 1 for use with an x-ray beam having a central ray, and wherein said diaphragm lamella has opposite ends with an axis extending between said opposite ends disposed perpendicularly relative to said central ray, and wherein said adjustment means comprises means for engaging said diaphragm lamella at said opposite ends for adjusting said opposite ends toward each other along said axis.
Claim 6
Dependent Claim
35 words
A radiation diaphragm as claimed in claim 1 wherein said diaphragm lamella has sides aligned perpendicularly relative to each other, and wherein said adjustment means comprises means for engaging said sides of said diaphragm lamella.
Claim 7
Dependent Claim
38 words
A radiation diaphragm as claimed in claim 1 wherein said adjustment means comprises a first holder engaging said diaphragm lamella and a second holder engaging said diaphragm lamella, and means for independently adjusting said first and second holders.
Claim 8
Dependent Claim
19 words
A radiation diaphragm as claimed in claim 1 wherein said diaphragm lamella is composed of rubber containing lead oxide.
Claim 9
Dependent Claim
19 words
A radiation diaphragm as claimed in claim 1 wherein said diaphragm lamella consists of a plurality of individual sub-lamellae.
Claim 10
Dependent Claim
23 words
A radiation diaphragm as claimed in claim 8 wherein said adjustment means includes means for adjusting said individual sub-lamellae relative to each other.
Claim 11
Dependent Claim
24 words
A radiation diaphragm as claimed in claim 1 wherein said diaphragm lamella is oriented by said adjustment means for use as a filter lamella.
Claim 12
Dependent Claim
83 words
A radiation diaphragm as claimed in claim 1 for use with an x-ray beam having a central ray, and wherein said diaphragm lamellae has a first axis disposed perpendicularly relative to said central ray and a second axis disposed perpendicularly relative to said central ray, said first and second axes being disposed substantially perpendicularly relative to each other, and wherein said adjustment means comprises means for engaging said diaphragm lameilae for flexing said diaphragm lamellae around each of said first and second axes.
Claim 13
Dependent Claim
63 words
A radiation diaphragm comprising a plurality of individual diaphragm lamellae that are initially aligned parallel to one another, at least one of said lamellae consisting of flexible material; and adjustment means, engaging each of said diaphragm lamellae for orienting each of said diaphragm lamellae, including flexing said at least one lamella, for setting a radiation absorption shape selectively matchable to different examination subjects.
Claim 14
Dependent Claim
63 words
A radiation diaphragm comprising a plurality of individual diaphragm lamellae that are initially aligned parallel to one another, at least one of said lamellae consisting of flexible material; and adjustment means, engaging each of said diaphragm lamellae for orienting each of said diaphragm lamellae, including flexing said at least one lamella, for setting a radiation absorption shape selectively matchable to different examination subjects.
