Abstract: Methods and systems are provided for an armboard adjustment assembly for a patient support table. In one embodiment, an armboard adjustment assembly is configured to retain a rotational position of an armboard of a patient support table via a plurality of one-way clutches, and in another embodiment the armboard adjustment assembly is configured to retain the rotational position of the armboard via a pair of friction pads. In this way, the armboard may be moved into a continuous plurality of positions between a fully lowered position and a fully raised position.

Abstract: A position landmarking system operative with respect to an object includes an operative device including a reference point and configured for movement in a direction relative to the object. The position landmarking system also includes a sensor configured for detecting a stimulus at a location on the sensor and to be disposed relative to the object and corresponding to the direction of movement of the operative device. In response to the stimulus, the reference point of the operative device and the location on the sensor are aligned with each other via movement of the operative device relative to the object. The operative device may be configured for performing an operation relative to a base, the operative device and the base configured for movement relative to each other. The sensor may be configured for communication with the operative device, the base or both.
