What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: The recall involves a risk-of-harm product (unnecessary radiation exposure) where injury has not yet been reported, fitting the criteria for a High severity score.

Plain-English summary

Siemens Medical Solutions USA, Inc. is recalling 1,301 units of the SOMATOM Perspective 16 CT scanner. These devices are intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data. The recall was initiated to inform customers of a potential issue with the CARE Dose4D algorithm.

The CARE Dose4D algorithm may incorrectly calculate tube current 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.
