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? or 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.

There is a potential issue that can lead to discordance between the simulated needle trajectory/tip position and the actual needle trajectory/tip position.

As part of the CT systems sub assembly, thirty-two (32) fasteners are used to attach the rotor to the bearing within the gantry. One or more of these fasteners may not be torqued to specification. If multiple fasteners are not torqued to specification, the rotor or rotor parts may become unsecured or displaced. While there has been no reported or observed event of expelled parts during gantry rotation, unsecured rotor parts may potentially be expelled.

If the screws of tube heat exchanger on the rotating scanner are not tightened well after replacing. This component may become detached and make contact with other components located within the Incisive CT systems during rotation. Other components could be damaged due to the contact with the tube heat exchanger.

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.

GE HealthCare has become aware of a potential issue on certain Revolution CT and Revolution Apex series CT systems (please see affected product details and the Appendix) that can result in coolant fluid (glycol) leaking onto the floor near the base of the gantry. The fluid is visible as it has a blue color. It is not corrosive and is not at a harmful temperature. However, there is a potential for injury if the fluid is not noticed and a person slips and/or falls.

Potential for a plan box not updated issue during Interventional procedure with Spectral CT that may lead to a collision with the operator or with the needle placed inside the patient, and an incorrect patient ID software issue that may lead to misdiagnosis.

GE HealthCare has become aware of a potential issue on certain Discovery, Optima, Revolution series CT systems, and certain operator console upgrades that can result in rotated CT images. Particularly with helical, cine, and cardiac (if applicable) scan modes, after the first image of an exam, each subsequent image can be rotated by an increasing amount. The amount of progressive image rotation is dependent on the gantry speed and the duration of the scan. The final image in the exam can be rotated up to a maximum of ~56 degrees. The entire anatomy rotates as a whole by equal degrees, without distortion, and the anatomical positioning and z-axis of the images remains correct. Small degrees of image rotation might not be noticed. If image rotation is noticed and necessitates a rescan of the patient, the same image rotation will reoccur.

Ziehm Imaging, Inc., distributor, have been informed by manufacturer, Ziehm Imaging GmbH that installed devices may not fully meet the requirements of IEC 60601-2-54 and or 21 CFR 1020.32(c) with respect to wired hand switch may fail when being exposed to mechanical stress such as shocks (e.g. dropping) or impacts can irreversibly damage the switching element in the hand switch. A defective switching element may then potentially initiate unintended radiation of the connected mobile X-ray unit.
