Abstract
Abstract The angiographic cradle disclosed herein permits a patient''s body to be supported and rotated around a predetermined axis to facilitate radiological studies. The cradle itself is movable on two transverse axes with respect to the axis of rotation so that the axis of rotation can be caused to pass through a selected portion of the patient''s body. In this way, changes in X-ray source and film plane spacings are avoided.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
Apparatus for manipulating a patient; an elongate cradle adapted to hold a patient; at each end of said cradle, a respective vertically movable carrier; drive means for vertically positioning each carrier; an axis member rotatably carried by each carrier; drive means for rotating said axis members relative to their respective carriers; at each end of said cradLe, means for traversing said cradle relative to the respective axis member along a first transverse axis; and at each end of said cradle, means for traversing said cradle relative to the respective axis member along a second transverse axis, said second transverse axis being substantially orthogonal to said first transverse axis.
Claim 2
Dependent Claim
108 words
Apparatus for manipulating a patient; an elongate cradle adapted to hold a patient; at each end of said cradle, a respective vertically movable carrier; drive means for vertically positioning each carrier; an axis member rotatably carried by each carrier; drive means for rotating said axis members relative to their respective carriers; at each end of said cradLe, means for traversing said cradle relative to the respective axis member along a first transverse axis; and at each end of said cradle, means for traversing said cradle relative to the respective axis member along a second transverse axis, said second transverse axis being substantially orthogonal to said first transverse axis.
Claim 3
Dependent Claim
133 words
Apparatus for locating a patient for radiological studies, said apparatus comprising: an elongate cradle adapted to hold a patient; at each end of said cradle, a support tower; supported by each tower, a respective vertically slidable carrier; associated with each tower, drive means for vertically positioning the respective carrier relative to the tower; an axis member rotatably carried by each carrier; drive means for concurrently rotating both of said axis members relative to their respective carriers; at each end of said cradle, means for traversing said cradle relative to the respective axis member along a first transverse axis; and at each end of said cradle, means for traversing said cradle relative to the respective axis member along a second transverse axis, said second transverse axis being substantially orthogonal to said first transverse axis.
Claim 4
Dependent Claim
133 words
Apparatus for locating a patient for radiological studies, said apparatus comprising: an elongate cradle adapted to hold a patient; at each end of said cradle, a support tower; supported by each tower, a respective vertically slidable carrier; associated with each tower, drive means for vertically positioning the respective carrier relative to the tower; an axis member rotatably carried by each carrier; drive means for concurrently rotating both of said axis members relative to their respective carriers; at each end of said cradle, means for traversing said cradle relative to the respective axis member along a first transverse axis; and at each end of said cradle, means for traversing said cradle relative to the respective axis member along a second transverse axis, said second transverse axis being substantially orthogonal to said first transverse axis.
Claim 5
Dependent Claim
29 words
Apparatus as set forth in claim 2 in which, when said cradle is substantially level, said first transverse axis is essentially horizontal and said second transverse axis is vertical.
Claim 6
Dependent Claim
21 words
Apparatus as set forth in claim 3 including a lead screw for moving said intermediate member relative to said axis member.
Claim 7
Dependent Claim
25 words
Apparatus as set forth in claim 3 in which said cradle is mounted on an elongate bar which is slidable relative to said intermediate member.
Claim 8
Dependent Claim
24 words
Apparatus as set forth in claim 2 wherein said drive means for vertically positioning each carrier includes a lead screw in the respective tower.
Claim 9
Dependent Claim
19 words
Apparatus as set forth in claim 6 including separate motor means for independently driving each of said lead screws.
Claim 10
Dependent Claim
60 words
Apparatus as set forth in claim 2 wherein said drive means for rotating said axis members includes a first gear element on each axis member and a second gear element journaled in the respective carrier and vertically slidable on a respective shaft adapted to couple rotation thereto and wherein said drive means includes also means for synchronously rotating said shafts.
Claim 11
Dependent Claim
155 words
Apparatus for locating a patient for angiographic studies, said apparatus comprising: an elongate cradle adapted to hold a patient; at each end of said cradle, a support tower; supported by each tower, a respective vertically slidable carrier; associated with each tower, drive means including a lead screw for vertically positioning the respective carrier relative to the tower; independent motor means for rotating each of said lead screws; an axis member rotatably carried by each carrier; an intermediate member which is movable along one transverse axis relative to said axis member, said one transverse axis being essentially vertical when said cradle is level; means for mounting said cradle on said intermediate member for movement on a second transverse axis which is substantially orthogonal to said one transverse axis, said second transverse axis being essentially horizontal when said cradle is level; and drive means for concurrently rotating both of said axis members relative to their respective carriers.
Claim 12
Dependent Claim
155 words
