Siemens COHERENCE RT Therapist Software Recalled for Performance Defects

Siemens Medical Solutions is recalling COHERENCE RT Therapist software versions due to performance defects and non-critical safety issues.

What this means for you

Minor labeling or packaging issue, or a voluntary precautionary recall. Risk of harm is low but real — follow the manufacturer's instructions.

Our severity reasoning: The source text explicitly states that the safety issues were not considered critical for immediate correction, and no injuries or illnesses are reported, fitting the criteria for a voluntary precautionary recall or low-risk issue.

The affected model is COHERENCE TH 2.0, Part No. 8139839, Current R630. These devices are intended to deliver X-ray photon and electron radiation for the therapeutic treatment of cancer.
