Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
An X-ray device, particularly for mammography, the device when oriented generally upright, comprising: a base, an arm extending generally horizontally from the base, the arm being vertically positionable relative to said base, the arm being axially extendible along a first horizontal axis, a support attached to said arm and pivotal relative to said arm about said first axis, the support having first and second parts defining a second axis between them, one being movable relative to the other along said second axis, an X-ray source carried by the first part, a film table carried by the second part, the support being pivotal relative to said arm about a third axis perpendicular to said first axis.
Claim 2
Dependent Claim
115 words
An X-ray device, particularly for mammography, the device when oriented generally upright, comprising: a base, an arm extending generally horizontally from the base, the arm being vertically positionable relative to said base, the arm being axially extendible along a first horizontal axis, a support attached to said arm and pivotal relative to said arm about said first axis, the support having first and second parts defining a second axis between them, one being movable relative to the other along said second axis, an X-ray source carried by the first part, a film table carried by the second part, the support being pivotal relative to said arm about a third axis perpendicular to said first axis.
Claim 3
Dependent Claim
