Within the same product category, the database holds 6 closely related recalls, of which 6 were also issued by FDA Devices. That clustering is a signal — repeated actions in a narrow category often indicate a systemic quality-control issue, a supplier-wide contamination, or a design defect that has propagated across product lines.

Reason for Recall

Hitachi discovered a software error that can occur when simultaneously scanning a patient while processing images previously acquired from a different patient. The software error can occur randomly.
