Abstract

Abstract A support for a patient, such as a chair, table or the like, is movably mounted on a track to slide horizontally, or move up and down, the track itself being rotatable within a ring-like frame forming a common structural support for the patient supporting device, as well as for an X-ray examining system including an Xray source and an X-ray receiver, so as to position the patient to have the region of the patient''s body to be examined at the center of the ring-shaped structure. The X-ray examining device itself is mounted on a two-axis gimbal, having its center of rotation coincident with the center of the ring-shaped structure, so that the same region of the patient''s body can be examined from all angular positions in three dimensions, that is, can be spherically examined.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 313 words
Radiological apparatus for examining a patient in any position in space comprising: a fixed base; a common structural support mounted on said base for rotation about a first horizontal axis; a pair of coaxial shafts rotatably mounted on said support to both sides of said first axis for defining a second axis perpendicular to said first one; a fork-shaped bracket having extremities respectively mounted on said shafts pair for rotation about said second axis; a further shaft mounted on said bracket, at about the middle thereof, for defining a third axis perpendicular to said second axis; said first, second and third axes intersecting at one point of intersection; an arm member mounted, at about its middle, on said further shaft for rotation about said third axis, said arm member having two extremities; an X-ray source mounted on one extremity of said member for emitting an X-ray beam, the central ray thereof transversing said intersection point; an X-ray receiver for supplying a visible picture mounted on the other extremity of said arm member in radiation receiving relation relatively to said X-ray source; a carrying member integral with said common structural support and including a straight portion parallel to said second axis; a mounting member mounted on said straight portion for displacement therealong; and means for supporting said patient movably, mounted on said mounting member, on the one hand, for rotation about a further axis parallel to a line perpendicular to both said first and said second axes and, on the other hand, for displacement in directions perpendicular to said straight portion, thereby allowing the locating of a predetermined organ within said patient''s body at said intersection point and the displacement of said X-ray source about a sphere whose center is located at said intersection point for carrying out X-ray examinations under substantially all possible angles of incidence of said X-rays relatively to said point.
