Plain-English summary
Siemens Medical Solutions USA, Inc. is recalling 1,301 units of the SOMATOM Emotion (2003) CT scanner. These devices are intended to produce cross-section images of the body by computer reconstruction of x-ray transmission data. The recall is due to possible incorrect tube current calculations by the CARE Dose4D algorithm specifically for head scans based on posterior-anterior (p.a.) or anterior-posterior (a.p.) topograms.
Depending on the geometrical shape of the skull bone, the calculated dose distribution may be inappropriate in rare cases. This error could lead to unnecessary radiation exposure for patients. The affected units were distributed nationally in the United States.
Customers should contact Siemens Medical Solutions USA, Inc. for further information regarding the recall and corrective actions.
