CT scanners recalled over six software faults affecting movement and dose

Plain-English summary

The Philips Incisive CT, product codes 728143 and 728144, running software versions 5.1.0.X and 5.1.1.X, is being recalled over six identified issues.

The firm describes: unintentional continued gantry or couch movement when a specific button series is used, requiring a manual stop; a Water Equivalent Diameter value that may set itself to zero during dose-modulated helical or axial scans, which may lead to an insufficient dose setting and noisy images; a software failure in which the ECG wave file is not saved, causing cardiac offline reconstruction to fail and the user to potentially rescan the patient; a fault in which patient orientation is changed to NULL under specific random scenarios, resulting in radiation delivered from the wrong orientation or position and producing incorrect and undiagnosable images; an inconsistent preview image display that skips images during scanning; and an auto ROI fault when mouse buttons are pressed together, which prevents the system from automatically triggering the subsequent clinical scan. Philips states there is a potential safety risk from additional tracker shots and/or rescanning a patient when the clinical scan is not triggered.

The recall covers 105 units distributed in Alabama, Arkansas, California, Connecticut, Florida, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, Ohio, Pennsylvania, Puerto Rico, Tennessee, Texas, Utah and Virginia, and internationally. The FDA has classified the action as Class II.

The enforcement record reports no injuries. Sites running the affected software versions should follow Philips' instructions.
