1. 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, the system comprising: 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 being configured to substantially extend around an entire periphery of the patient; and a buffer positionable between the barrier and the patient for offsetting the barrier from the patient, the buffer being discrete from the barrier and comprising at least one flexible bag configured to retain a fluid, wherein the at least one flexible bag is configured to improve a clarity of the image generated during the radiological examination.
