A collimator includes a panel and one or more blades. The panel defines an exit port, and the one or more blades are held between the panel and an X-ray source to cover at least a portion of the exit port. Each of the one or more blades has a primary blocking member and a secondary blocking member with material densities sufficient to block X-ray radiation. The primary blocking member shapes an X-ray beam emitted from the X-ray source. The secondary blocking member is secured in a fixed position relative to the primary blocking member between the primary blocking member and the panel to block scatter radiation from the X-ray beam from emanating through the exit port. The primary blocking member has a substantially non-planar surface facing toward the X-ray source. The secondary blocking member has a substantially planar surface facing toward the X-ray source.

X-ray collimator for imaging system

A shaft alignment component for aligning a rotatable shaft positioned within a housing of a driven device with a motor shaft of a motor positioned outside of the housing of the driven device is disclosed. The component includes a body portion having an opening formed therethrough to receive the rotatable shaft and/or the motor shaft therein, a first alignment feature configured to interface with an alignment hub on the motor to position the motor shaft along a centerline axis of the shaft alignment component, and a second alignment feature comprising a chamfered surface configured to interface with a countersunk feature on the housing. The chamfered surface is configured to interface with the countersunk feature to self-align the shaft alignment component with the housing such that the rotatable shaft of the driven device is positioned along the centerline axis of the shaft alignment component and aligned with the motor shaft.
