<p>A multi-axis profiling x-ray machine for making angiographic examinations includes an L arm (10) rotatable about a first machine axis (76) intersecting an isocenter (80), the L arm (10) defining a second machine axis (78) intersecting the isocenter and perpendicular to the first machine axis. An offset arm (68) is rotatable about the second machine axis and includes a curved guide collar (24) holding a C arm (22). The C arm (22) slides along the collar to move an x-ray source (14) mounted on one end of the C arm and an image receiver (16) mounted on the other end of the C arm about a third machine axis (74) perpendicular to the second machine axis. The three axes permit isocentric profiling motion about an arbitrary angle in three dimensions.</p> |
