  • Pre-object filter for shaping profile of radiation attenuation in fan-angle direction
    Patent number: 11083422
    Abstract: Among other things, one or more systems and/or techniques are described for shaping a profile of radiation attenuation in a fan-angle direction via a pre-object filter (e.g., a bowtie filter) based upon a profile of an object. For example, a pre-object filter may be at least partially rotated about a filter axis and/or may be translated in a direction parallel to a direction of conveyance of the object under examination to adjust a profile of radiation attenuation in the fan-angle direction. Further, in one embodiment, the profile of radiation attenuation may be reshaped during rotation of the radiation source about the object to adjust an amount of radiation attenuation in the fan-angle direction (e.g., to adjust a profile of radiation attenuation as a shape of the object changes from a perspective of a radiation source as the radiation source is rotated about the object).
