  • Patent number: 9271685
    Abstract: A radiation attenuation system is provided. The radiation attenuation system includes a first shield panel formed of a first radiation attenuating material, a second shield panel formed of a second radiation attenuating material, and a frame disposed below the first shield panel and the second shield panel. The frame includes a first end portion defining a first array of slots and a second end portion defining a second array of slots. The first array of slots and the second array of slots are configured to receive the first shield panel and the second shield panel such that the second shield panel is spaced apart from the first shield panel to form a first trough sized to fit a limb of a patient.

  • Patent number: 8487287
    Abstract: A system for attenuating a primary radiation beam applied to a target area on a patient for generating an image of the target area during radiological examination includes a barrier formed of a radiation attenuation material and positionable over the target area to partially attenuate the primary radiation beam before the primary radiation beam reaches the target area. The barrier is configured to substantially extend around an entire periphery of the patient. The system also includes a buffer positionable between the barrier and the patient for offsetting the barrier from the patient. The buffer includes at least one flexible bag configured to retain a fluid. The at least one flexible bag is configured to improve the clarity of the image generated during the radiological examination.

  • Patent number: 7767990
    Abstract: A radiation attenuation system for attenuating radiation during lateral radiographic imaging of an object is provided. The system includes a first radiation attenuating barrier that is substantially conformable to the object and configured to at least partially cover the object. The first radiation attenuating barrier has a fenestration area defining at least one opening. The system further includes a second radiation attenuating barrier coupled to the first radiation attenuation barrier. The second radiation attenuating barrier is selectively movable between a collapsed position and a generally upright position relative to the first radiation attenuating member.

  • Patent number: 7667214
    Abstract: A radiation attenuation system for shielding from scatter radiation one or more portions of a patient that are not of primary interest to a particular radiological procedure (i.e., non-target areas, etc.). The radiation attenuation system may be configured to shield the head of a patient (such as the head of a pediatric patient), and/or any other portion of the patient that may benefit from being shielded from scatter radiation. The radiation attenuation system is preferably configured to conform to the contours of the patient. The radiation attenuation system may be a flexible member that can be reconfigured to accommodate patients of varying size.

  • Patent number: 7591590
    Abstract: A radiation attenuation system for use with Computed Tomography procedures and a Computed Tomography having a radiation attenuation system are disclosed. The radiation disclosed attenuation system includes a shield made of a flexible radiation attenuation material and an interface supporting the shield at the Computed Tomography machine. The interface allows the shield to be selectively added to and removed from the Computed Tomography machine. The disclosed Computed Tomography machine includes a gantry defining an opening through which a patient table is at least partially inserted during a Computed Tomography procedure and a housing enclosing the gantry without substantially covering the opening and remaining fixed relative thereto. The housing is at least partially defined by a front panel that is formed of a substrate and a radiation attenuation material. The radiation attenuation material is in the form of a flexible sheet and is fixed relative to the substrate.
