Abstract: A radiation shield for use in connection with computed tomography (CT) calcium scoring of a target area of a patient is provided. The shield is configured for placement over the target area and over one or more radiosensitive secondary areas adjacent to the target area such that x-rays are transmitted through the radiation shield and the target area for detection by an x-ray detector. The detected radiation can be processed for use in a calcium scoring procedure. The radiation shield is configured to reduce radiation exposure of the radiosensitive secondary areas during the calcium scoring procedure without substantially reducing the accuracy of the calcium score associated with the target area.
