Plain-English summary
Philips Medical Systems DMC GmbH is recalling ProxiDiagnost N90 radiography and fluoroscopy systems for a firmware issue affecting the Wallstand VS2 component. The recall involves 140 systems distributed nationwide.
The firmware issue in the Wallstand VS2 board causes the system to rotate the radiation field selection by 90 degrees. This occurs when the system is restarted with Table Height 2 as the default setting and then switched to Wallstand VS2, or after the first exposure using Wallstand VS2 followed by a system restart. The incorrect field selection may cause an incorrect radiation dose. The anatomic position markers may also become mispositioned and could potentially correspond to the opposite side of the anatomy being examined.
