On a diagnostic x-ray table, a first group of x-ray shielding panels are supported for rotation on a carrier and another group of panels are supported on a lever that is pivotally connected to the carrier. The lever may be aligned with the carrier to present the combined width of all panels across the front of a combination spot film and fluoroscopic device. Means responsive to pivoting the lever along the side of the apparatus rotate the first group of panels to substantial parallelism with second group to present the panels along the side of the apparatus when the spot film and fluoroscope device is angulated to put the patient being examined in an erect posture.
