Abstract

Abstract X-ray apparatus carrying an X-ray tube as a source and an image intensifier as a receptor on opposite ends of a two-limbed C-Arm has a horizontal support arm extending from a base to a vertical support arm for the C-arm. The vertical arm has a plurality of telescoping tubular sections which can be extended or contracted along a vertical axis to raise or lower the C-arm relative to the level of the base. The horizontal arm also extends telescopingly to increase the space between the base and C-arm to give free passage of medical personnel through the space, the base having a height sufficient to hold the horizontal arm above a moderately tall operator. The horizontal arm is pivoted on a vertical axis through the base to swing the C-arm, X-ray tube and image intensifier over a patient table in coordination with extension of the horizontal arm or rotation of the vertical arm sections to scan the X-ray tube and receptor over a large area of the patient table. All movements may be manual or motorized. The X-ray apparatus and patient table may be fixed or mobile.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 78 words
X-ray appararus for examination of a patient comprising: an upright base; a two-limbed support with a X-radiation source on one limb and an X-radiation receptor on the other limb; a horizontal support arm extending from the base; and a vertical support arm extending from the horizontal arm to the two-limbed support including a plurality of telescoping tubular sections extendible along a vertical axis to lower the two-limbed support and the X-radiation source and receptor relative to the base.
Claim 2
Dependent Claim 78 words
X-ray appararus for examination of a patient comprising: an upright base; a two-limbed support with a X-radiation source on one limb and an X-radiation receptor on the other limb; a horizontal support arm extending from the base; and a vertical support arm extending from the horizontal arm to the two-limbed support including a plurality of telescoping tubular sections extendible along a vertical axis to lower the two-limbed support and the X-radiation source and receptor relative to the base.
Claim 3
Dependent Claim 26 words
Apparatus according to claim 1 wherein the vertical support arm is rotatable about the vertical axis to swing the X-radiation source and receptor about the axis.
Claim 4
Dependent Claim 18 words
Apparatus according to claim 1 including first motor means to drive the vertical arm along the vertical axis.
Claim 5
Dependent Claim 18 words
Apparatus according to claim 3 including second motor means to rotate the vertical arm about the vertical axis.
Claim 6
Dependent Claim 18 words
Apparatus according to claim 4 including control means on the vertical arm for energizing the first motor means.
Claim 7
Dependent Claim 33 words
Apparatus according to claim 1 wherein the horizontal support arm comprises a plurality of tubular telescoping sections extendible along a horizontal axis to extend the radiation source and receptor away from the base.
Claim 8
Dependent Claim 57 words
Apparatus according to claim 2 wherein the horizontal support arm comprises a plurality of tubular telescoping sections extendible along a horizontal axis to extend the radiation source and receptor away from the base simultaneously with swinging of the source and receptor about the vertical axis, so as to move the source and receptor along a straight line.
Claim 9
Dependent Claim 18 words
Apparatus according to claim 7 including third motor means to extend the horizontal arm along the horizontal axis.
Claim 10
Dependent Claim 40 words
Apparatus according to claim 1 wherein the base is of a height to hold the horizontal arm above an operator so as to permit passage of the operator between the base and vertical arm when the horizontal arm is extended.
Claim 11
Dependent Claim 20 words
Apparatus according to claim 3 including electric wiring through the tubular horizontal and vertical arms to the first motor means.
Claim 12
Dependent Claim 19 words
Apparatus according to claim 3 including a control switch on the vertical arm connected to the first motor means.
Claim 13
Dependent Claim 33 words
Apparatus according to claim 3 including a control switch on the vertical arm connected to the first motor means, the switch being readily accessible to the operator when the horizontal arm is extended.
Claim 14
Dependent Claim 30 words
Apparatus according to claim 1 wherein the horizontal arm is pivotally mounted on the base for rotation about a vertical axis parallel to the vertical axis of the vertical arm.
Claim 15
Dependent Claim 46 words
Apparatus according to claim 6 wherein the horizontal arm is pivotally mounted on the base for rotation about a vertical axis parallel to the vertical axis of the vertical arm so that the X-radiation source and receptor can be guided over a substantial area of examination.
Claim 16
Dependent Claim 13 words
Apparatus according to claim 1 wherein the base is mobile on rolling means.
Claim 17
Dependent Claim 21 words
Apparatus according to claim 1 wherein the base and two-limbed support are electrically connected through the horizontal and vertical support arms.
Claim 18
Dependent Claim 21 words
Apparatus according to claim 6 wherein the base and two-limbed support are electrically connected through the horizontal and vertical support arms.
Claim 19
Dependent Claim 11 words
Apparatus according to claim 1 in combination with a patient table.
