Azurion Medical Imaging System Software Defect Alters Dose Parameters
A software defect in Philips Azurion imaging systems causes the Patient Type to change unexpectedly during study initiation, altering dose control parameters without operator notification.
The agency’s classification
FDA (Devices): Class II
Class II is a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences, or where the probability of serious adverse health consequences is remote.

Plain-English summary
Philips Medical Systems Nederland B.V. is recalling Azurion systems with software release R1.x due to a software defect affecting dose control. Approximately 722 units have been distributed nationwide and worldwide.
The defect occurs in the "Add Study" function. When a user selects a Patient Type and initiates the study by pressing "Start Procedure," the software inadvertently changes the Patient Type to a different option without notifying the operator. Since Patient Type is a factor in the dose control process, this unannounced change causes the system to apply incorrect technique factors without user awareness.
