MHI-TM2000 Linear Accelerator System Software Recall for Communication Errors

Mitsubishi Heavy Industries is recalling 11 MHI-TM2000 Linear Accelerator Systems due to a software defect that allows radiation delivery despite communication errors and prevents saving treatment records.

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 medical device where a software error could lead to unintended radiation delivery or loss of critical treatment records, representing a risk of harm where injury has not yet been reported.

Plain-English summary

Mitsubishi Heavy Industries, Ltd. is recalling 11 units of the MHI-TM2000 Linear Accelerator System, specifically those running Software Version 3.5.0 and 3.5.1. The affected units are distributed worldwide, including in the United States (Florida, New York, Ohio, and Texas) and internationally in Belgium, Italy, Korea, France, and Germany.

The recall is due to a software defect where the operator console allows users to deliver therapeutic radiation to patients even when a specific communication error relevant to imaging conditions has occurred. Additionally, the treatment record, which documents the delivered radiation, cannot be saved when this error occurs.

Healthcare facilities using these systems should contact the manufacturer to arrange for the necessary software updates or repairs. Patients who received treatment on these systems during the affected period should consult their healthcare providers regarding the integrity of their treatment records.
