Abstract:
1. A medical radiation scanning device for imaging a region of a patient's body, comprising: a gantry defining a space for receiving said region of a patient's body; a source of a scanning beam of radiation movable around said region of a patient's body; a radiation shield fixed in the gantry in stationary relationship to the movable scanning beam at a location that attenuates the movable scanning beam of radiation only while the movable scanning beam of radiation passes over a relatively vulnerable portion of said region of the patient's body while said region of the patient's body is in said space; wherein the medical radiation scanning device is a CT body scanner that uses said scanning beam of radiation having a spectrum of X-radiation energy, and the low energy portion of the X-ray spectrum is preferentially attenuated by the radiation shield while the high energy portion passes through the radiation shield substantially unaffected.
