Abstract
Abstract X-ray diagnostic apparatus including a chair for the patient having a vertical plane of symmetry in which lies the central Xray beam. The chair has a headrest which may be adjusted into a fixed position for the head of the patient and is supported on an arm extending from the base and in the plane of the base and is spaced a fixed distance from a column supporting the X-ray emitter. A horizontal boom arm extends from the column and is carried by a carrier member extending parallel to the vertical plane of symmetry of the chair. The boom arm is adjustable along said carrier member toward and from the chair. The horizontal boom arm is adjustable about its longitudinal axis. The X-ray emitter is carried in a protective casing extending perpendicular to the boom and is positioned to lie in the vertical plane of symmetry of the chair. The boom and chair are vertically adjustable and the chair is pivotally movable about a vertical axis extending along the vertical plane of symmetry of the chair.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
246 words
An X-ray diagnostic device adapted for positioning a patient in a predetermined position relative to the X-ray emitter, for Xraying a patient by insertion of an X-ray anode into a body cavity comprising, a base having a top surface portion lying in a horizontal plane, a chair for the patient having a vertical plane of symmetry extending perpendicularly to said base and having a fixedly attached headrest for the head of a patient, positioning the heat of the patient along the vertical plane of symmetry of the chair, a vertical column extending upwardly from said base in parallel spaced relation relative to said chair, an upper horizontal boom fixedly attached to said column and extending from said column in parallel relation with respect to the horizontal plane of said base, a housing on the end of said boom mounted for adjustable movement about an axis coaxial with the axis of said boom and perpendicular to the plane of symmetry of the chair, an X-ray emitter including a high-voltage source, carried by said housing, and said housing including a protective casing extending at right angles to said boom and said X-ray emitter being carried in said protective casing having an anode extending from said casing having a longitudinal axis lying in the vertical plane of symmetry of said chair, and means for altering the distance between said anode and said chair without altering the location of said anode from said vertical plane of symmetry of said chair.
Claim 2
Dependent Claim
246 words
An X-ray diagnostic device adapted for positioning a patient in a predetermined position relative to the X-ray emitter, for Xraying a patient by insertion of an X-ray anode into a body cavity comprising, a base having a top surface portion lying in a horizontal plane, a chair for the patient having a vertical plane of symmetry extending perpendicularly to said base and having a fixedly attached headrest for the head of a patient, positioning the heat of the patient along the vertical plane of symmetry of the chair, a vertical column extending upwardly from said base in parallel spaced relation relative to said chair, an upper horizontal boom fixedly attached to said column and extending from said column in parallel relation with respect to the horizontal plane of said base, a housing on the end of said boom mounted for adjustable movement about an axis coaxial with the axis of said boom and perpendicular to the plane of symmetry of the chair, an X-ray emitter including a high-voltage source, carried by said housing, and said housing including a protective casing extending at right angles to said boom and said X-ray emitter being carried in said protective casing having an anode extending from said casing having a longitudinal axis lying in the vertical plane of symmetry of said chair, and means for altering the distance between said anode and said chair without altering the location of said anode from said vertical plane of symmetry of said chair.
Claim 3
Dependent Claim
78 words
An X-ray diagnostic device in accordance with claim 1, wherein the means for altering the distance between the anode and the chair includes a horizontal carrier mounted on said column and extending parallel to the vertical plane of symmetry of said chair and being horizontally adjustably movable along a plane parallel to the plane of symmetry of the chair and having said boom fixedly attached thereto and extending perpendicularly thereto for movement therewith toward and from the chair.
Claim 4
Dependent Claim
56 words
An X-ray diagnostic device in accordance with claim 2, wherein the means for altering the distance between the anode and the chair also includes means for adjusting the height of said vertical column, means mounting said anode for movement about the axis of said boom, and means holding said anode in a selected position of adjustment.
Claim 5
Dependent Claim
61 words
An X-ray diagnostic device in accordance with claim 1, wherein the protective casing containing the X-ray emitter has a portion containing the high-voltage source and forming an axially aligned extension of said boom, and another portion extending in the plane of symmetry of the chair and containing the anode and positioning the anode in the plane of symmetry of the chair.
Claim 6
Dependent Claim
151 words
An X-ray diagnostic device in accordance with claim 2, wherein the means for altering the distance between the anode and the chair includes a horizontal carrier disposed on said column adjacent the top thereof and extending parallel to said vertical plane of symmetry of the chair, and adjustably movable with respect to said column in a horizontal direction parallel to said plane of symmetry of said chair and toward and from said chair, wherein said boom is rigidly connected to said carrier and extends at right angles thereto, wherein the housing is a T-shaped casing having a leg portion carried by said boom for adjustable movement about the longitudinal axis of said boom, and having a cross portion extending perpendicular to said leg portion having said anode extending from one end thereof and means at the opposite end thereof for adjustably moving said anode about the longitudinal axis of said boom.
Claim 7
Dependent Claim
81 words
An X-ray diagnostic device in accordance with claim 2, wherein the housing is of T-shaped configuration and includes a leg portion forming an extension of the boom and rotatable about the axis of the boom and a cross portion extending perpendicularly to said leg portion and having an axis extending along the plane of symmetry of the chair, wherein a high-voltage transformer is carried in said leg portion, and wherein an X-ray tube and anode are carried in said cross portion.
Claim 8
Dependent Claim
78 words
An X-ray diagnostic device in accordance with claim 6, wherein the anode extends from one end of said cross portion along the plane of symmetry of the chair, wherein a handle is at the opposite end of said cross portion, and manual release means are mounted on said cross portion in access to a hand placed on the handle, to release said housing for adjustment about the axis of said boom, and to hold said housing in position.
Claim 9
Dependent Claim
41 words
The X-ray diagnostic device of claim 7, wherein a magnetic brake is provided to hold said housing and anode in a selected position of adjustment, and wherein the manual release means includes a push button in close proximity to said handle.
Claim 10
Dependent Claim
45 words
The X-ray diagnostic device in accordance with claim 8, wherein a casing is mounted on said base and extends upwardly along said vertical column, and wherein a counterbalance device and controls for controlling low-voltage and current supplied to said transformer are contained in said casing.
