PHILIPS MEDICAL SYSTEMS Recalls

Hazard: The clinical CT scan may not automatically trigger after the Bolus Tracking scan and may need to be triggered manually. Additional Bolus Tracking shots may occur. This may result in the clinical acquisition being inadequate for diagnosis, causing a potential for patient rescan and receiving additional radiation.

Hazard: Philips has identified three software issues: 1. During a continuous CT (CCT) scan, there is the potential that the Gantry could remain at the current scan position after pressing Go. 2. Potential where the message of Previous Surview Exists Select Previous Surview? <Yes> or <No> should display but does not appear. 3. After performing Surview and planning the Brain Helical acquisition by setting Brain Area DoseRight Index to increase the dose, there is the potential that the Define Head Area option in the context menu is grayed out.

Hazard: Issue 1: The potential for unintentional continued gantry/couch movement when a specific button series is used requiring use of manual stop. Issue 2. When performing a helical/Axial scan with ORI (Dose Right index)/ DOM (Dose Modulation), the WED (Water Equivalent Diameter) value might set itself to zero, and this may lead to an insufficient dose setting after the surview. If operator misses the insufficient dose and the WED value in User Interface and continues with the subsequent helical/Axial scans, then the obtained images will be noisy due to low dose setting. Issue 3: Due to a software failure, the ECG wave file is not saved. As a result, the cardiac offline image reconstruction fails due to the missing ECG wave file, and the user might rescan the patient. Issue 4: This issue is software fault in which the patient orientation will be changed to NULL under specific random scenarios resulting in radiation being delivered from the wrong orientation (surview scan) or in the wrong position (clinical scan) and will generate incorrect and undiagnosable surview/clinical images. Patients may be rescanned for surview and/or clinical images. Issue 5: During scanning, the preview image display is not consistent, the images are not arriving at a fixed rate, skipping images from time to time during scanning. The obtained images might not support making the clinical diagnosis and the user might decide to re-scan the patient. Issue 6: If a user presses the left and middle/right mouse buttons together or afterwards in a short time, both commands are executed and an incorrect auto ROI is created. This ROI coordinates won t be assigned as the object is empty. As a result, the threshold of contrast level will not be reached in the UI and this will prevent the system from automatically triggering the subsequent clinical scan. There is potential safety risk identified for additionally tracker shots and/or rescan of a patient when the clinical scan is not triggered. This issue only affects the manual ROI process.

Hazard: While performing a fluoroscopy examination, there is a potential that the Radio Fluoroscopy (RF) viewer will also display a previous patient's radiography images. If the issue occurs, there will be differences in image content, image format and image size.

Hazard: A software issue that can incorrectly label all captured images that may lead to misdiagnosis and subsequent incorrect treatment.

Hazard: The infant performance test did not meet the test specification for the Infant Head Uniformity test with High Resolution. As a result, when the user performs High Resolution head scans, the reconstructed images may exhibit degraded image quality manifested as non-uniformity of the image, CT number shift greater than 5 Hounsfield units, and reduction in gray/white matter differentiation. The issue is most sever in the High Resolution mode, and the factory reference pediatric scan protocols are set to High Resolution default. Adults head scans have a factory reference protocol that defaults to standard resolution which doesn't experience the issue.

Hazard: In DS/US proton planning, there is a correction factor used internally to the dose engine that is calculating improperly in some cases. This can result in an incorrect dose calculation.

Hazard: Sp02 and/or Non Invasive Blood Pressure (NBP) alarms may become disabled without visual notification
