Abstract
Abstract The X-ray apparatus is especially well adapted for taking mammograms; that is, X-ray pictures of the female breast. A single upright supporting column and a patient chair are mounted on a platform. The column supports a counterbalanced vertically movable member which in turn supports a horizontally movable arm. A head is adjustably rotatable about the horizontal axis of the arm. An X-ray source and a cassette carrier are mounted on opposite portions of the head. The arm is movable horizontally toward and away from the front of the chair, which is movable horizontally along the platform at right angles to the movement of the arm. The X-ray source is preferably movable along the head, toward and away from the cassette carrier for making mammograms in which the breast is compressed. A control console is preferably mounted on the platform and is screened from the Xray source by a protective wall.

Claim 1
Independent Claim
234 words
Apparatus for taking X-ray pictures of the female breast, said apparatus comprising a platform, a single supporting column mounted on said platform and projecting upwardly therefrom, a counterbalanced mounting member mounted on said column and movable vertically therealong, a supporting arm, means mounting said supporting arm on said mounting member for horizontal movement relative thereto, a supporting head mounted on said supporting arm for rotary adjustment about a horizontal axis, an X-ray source mounted on one portion of said head, a cassette carrier mounted opposite said X-ray source on said head, and substantially perpendicular to the axis of said X-ray source, a patient-supporting chair projecting upwardly from said platform, said supporting arm being movable parallel to said horizontal axis and toward and away from the front of said chair, means mounting said chair on said platform for horizontal movement at right angles to the movement of said supporting arm, and means mounting said X-ray source on said head for limited movement toward and away from said cassette carrier for taking X-ray pictures in which the breast is under compression between said X-ray source and said cassette carrier, said X-ray source and said cassette carrier being rotatable with said head, but being fixed in angular positions relative to said head, the rotary adjustability of said head making it possible to compress the breast in any desired direction between said X-ray source and said cassette carrier.
Claim 2
Dependent Claim
234 words
Apparatus for taking X-ray pictures of the female breast, said apparatus comprising a platform, a single supporting column mounted on said platform and projecting upwardly therefrom, a counterbalanced mounting member mounted on said column and movable vertically therealong, a supporting arm, means mounting said supporting arm on said mounting member for horizontal movement relative thereto, a supporting head mounted on said supporting arm for rotary adjustment about a horizontal axis, an X-ray source mounted on one portion of said head, a cassette carrier mounted opposite said X-ray source on said head, and substantially perpendicular to the axis of said X-ray source, a patient-supporting chair projecting upwardly from said platform, said supporting arm being movable parallel to said horizontal axis and toward and away from the front of said chair, means mounting said chair on said platform for horizontal movement at right angles to the movement of said supporting arm, and means mounting said X-ray source on said head for limited movement toward and away from said cassette carrier for taking X-ray pictures in which the breast is under compression between said X-ray source and said cassette carrier, said X-ray source and said cassette carrier being rotatable with said head, but being fixed in angular positions relative to said head, the rotary adjustability of said head making it possible to compress the breast in any desired direction between said X-ray source and said cassette carrier.
Claim 3
Dependent Claim
17 words
Apparatus according to claim 1 in which said head contains means for counter balaNcing said X-ray source.
Claim 4
Dependent Claim
16 words
Apparatus according to claim 1 including a motor for adjusting the position of said X-ray source.
Claim 5
Dependent Claim
17 words
Apparatus according to claim 3, including magnetic braking means for stopping the movement of said X-ray source.
Claim 6
Dependent Claim
23 words
Apparatus according to claim 1, including a control console mounted on said platform for controlling the operation and movement of the X-ray source.
Claim 7
Dependent Claim
27 words
Apparatus according to claim 5, including a protective wall mounted on said platform between said control console and the X-ray source to screen the operator against radiation.
