Abstract
The preferred embodiment of the disclosed invention comprises rotary actuators that move one or more x-ray attenuating plates in the x-y plane (ie. image plane). These x-ray attenuating plates attenuate the x-ray beam with thin metal sheets or plates that contain one or more apertures, which fully exposes the desired region of interest (ROI) while filtering the rest of the image, reducing the radiation exposure for the procedure. The devices will typically have a selection of many attenuation profiles. A small aperture or low attenuation profile region will result in a higher total exposure reduction and a large aperture or large attenuation profile will result in a smaller exposure reduction. The x-ray attenuating plate can be rotated to select an attenuation profile using a detent wheel.
