Radiology instrument comprising an X-ray tube linked with a plane detector. A support device comprises a pedestal of overall L-shape resting on the floor, with a substantially horizontal base, a substantially vertical post and an axis of rotation passing through one end of the base, the post being fixed to the other end of the base and being parallel to the axis, a bracket which is fixed to the top of the post and can rotate about a horizontal axis, and a C-shaped arm which is mounted on the bracket and is capable of rotating about an axis substantially perpendicular to the horizontal axis by sliding on bracket, the tube and the detector being mounted on bow and facing one another, the axis of the bracket the axis of the arm being secant at a point in space referred to as the isocenter. The instrument comprises a means for moving the isocenter continuously along a longitudinal axis of a patient held static.

Radiology instrument

An electrophysiology table includes a dual section table top comprising a pair of elongated planar sections in superimposed planar to planar relationship. One of the table top sections is adapted to be manually moveable axially horizontally over the other section, the other section is electric motor powered for axial horizontal motion to advance the dual section table top to a new position where the manual moveable section is optimized. The table is also adapted to be vertically adjusted as well as to be tilted or angulated. With the two sections locked, the motorized section may move the table along the tilt slope.

Electrophysiology table

A multi-axis profiling x-ray machine for making angiographic examinations includes an L arm rotatable about a first machine axis intersecting an isocenter, the L arm defining a second machine axis intersecting the isocenter and perpendicular to the first machine axis. An offset arm is rotatable about the second machine axis, and includes a curved guide collar holding C arm. The C arm slides along the collar to move an x-ray source mounted on one end of the C arm and an image receiver mounted on the other end of the C arm about a third machine axis perpendicular to the second machine axis. The three axes permit isocenter profiling motion about an arbitrary angle in three dimensions.

X-ray positioner for multi-axis profiling

An X-ray source is mounted in an enclosure for angulating longitudinally about a horizontal axis. An X-ray permeable patient supporting table is mounted on the top of the enclosure for executing lateral and longitudinal movements. An X-ray image receiving device such as an X-ray image intensifier is mounted above the table on a vertically movable arm which is on a longitudinally movable carriage. Electric control means are provided for angulating the X-ray source and image intensifier synchronously as the image intensifier system is shifted longitudinally or vertically such that the central ray from the X-ray source is kept perpendicular to the image input plane of the image intensifier.
