Siemens recalls SOMATOM Spirit CT scanners that may calculate incorrect radiation doses for head scans, potentially leading to unnecessary exposure. Affected units may need correction to ensure safe imaging.
to inform customers of possible incorrect tube current calculations by the CARE Dose4D algorithm for head scans based on p.a. (posterior-anterior) or a.p. (anterior-posterior) topograms. Depending on the geometrical shape of the skull bone, it may happen in rare cases that the calculated dose distribution is not appropriate and could lead to unnecessary radiation exposure
Siemens is recalling its SOMATOM Spirit CT scanners because a software algorithm might calculate incorrect radiation doses during head scans. This could lead to unnecessary radiation exposure in rare cases, though the risk is low.
The CARE Dose4D algorithm may miscalculate radiation doses for head scans based on skull geometry. In rare cases, this could result in unnecessary radiation exposure, but the risk is low and not immediate.
Patients undergoing head CT scans at facilities using the recalled scanners. Medical staff and patients are most at risk if the scanner is used without correction.

Look for the SOMATOM Spirit model name on the scanner's label or documentation.
The recall indicates a rare risk of unnecessary radiation exposure, but it is not an immediate hazard. Siemens states the risk is low.
