Philips DigitalDiagnost 4 Flex/Value radiography systems have a firmware issue in the Wallstand VS2 board that may cause incorrect image orientation and radiation dosing. The defect affects 140 systems distributed nationwide.
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: This is a Class II recall with no reported injuries or hospitalizations. The defect presents a risk of incorrect radiation dosing and anatomical positioning errors in a medical imaging system. Since the hazard is real but no patient harm has been reported, this meets the rubric criterion for High severity: risk-of-harm products where injury has not yet been reported.
Plain-English summary
Philips Medical Systems is recalling 140 DigitalDiagnost 4 Flex/Value radiography and fluoroscopy systems distributed nationwide in the United States. The systems contain a firmware issue in the Wallstand VS2 board.
Following a system restart where Table Height 2 (TH2) is the default setting and then switched to Wallstand VS2, or following the first exposure using Wallstand VS2 and a subsequent system restart, the Wallstand VS2 firmware may rotate the amplimat field selection by 90 degrees. This can result in incorrect image orientation on the first examination and incorrect radiation dosing. Additionally, anatomic position markers may become mispositioned and could be associated with the opposite side of the anatomy.
The affected serial numbers are: 10001088, 10001097, 10001104, 10001112, 19000317, 10001095, 10001102, and 10001105.
Healthcare facilities operating these systems should contact Philips Medical Systems DMC GmbH for firmware updates or technical guidance to resolve this issue.
