Organ-based computed tomographic (CT) radiation dose reduction to the lenses: impact on image quality for CT of the head.

Purpose: Recently, a new specific organ dose adaption and reduction protocol, or SODAR tool (X-CARE, Siemens Healthcare), which reduces dose to the anterior aspect of the body of patients, was installed on our computed tomographic scanner. The purpose of this pilot project was to evaluate image quality and dose distribution in the acquired data with the new protocol.

Materials And Methods: Sixteen consecutive patients were scanned with the new SODAR head protocol.
