An imaging table for medical examination and imaging procedures. A tilting imaging table comprises a rectangular base frame on wheels, a column extending upwardly from the base, and a tilt assembly which includes a pair of rotatable pivot arms at the top of the column. A radiolucent table top for imaging purposes is removably secured to the tilt assembly. At least two interchangeable radiolucent table tops, of different configurations and used for different medical imaging purposes, accompany the tilting imaging table and may be secured removably, one at a time, to the tilt assembly. This tilt assembly and any table mounted thereon are tiltable about a transverse axis between a head up position (e.g, 30 DEG head up) and a head down position (e.g., 30 DEG head down). Greater degree of tilt in one direction can be provided if desired. Also shown is a limit stop mechanism for retaining a tilting assembly including pivot arms in a horizontal position. This mechanism includes a solenoid operated swinging arm which engages a limit stop affixed to a pivot arm when the solenoid is not energized. When the solenoid is energized, a plunger and a link pivotally attached thereto are pulled downwardly against the bias of a compression spring, causing the swinging arm to be rotated out of engagement with the limit stop, so that the tilt assembly including pivot arms is free to rotate. This limit stop mechanism can be used both with the imaging table described in detail herein and with other longitudinally tiltable image tables.
