Due to a software issue where the process of patient scanning, the scatter correction may occasionally fail with will potentially cause a failure of the PET image reconstruction and generation of PET images.

The wireless VSM module of a mobile PET/CT system, operating in an environment with strong Wi-Fi signals, may experience ECG signal and respiratory signal loss due to Wi-Fi interference. ECG and respiratory signal loss during acquisition can result in the failure of ECG and respi…

The EXAM acquisition workflow could occasionally freeze after canceling the PET scan.

There is a potential for the X-Ray tube head (Touch screen interface) to perform an uncommanded motion. This could result in a collision with the patient.

A potential issue of an incorrect CT scan delay timer to be displayed on the gantry Digital Display Panel (DDP) during multi-phase contrast scanning. This could lead the operator to receive unnecessary exposure to radiation.

1) Service function problem may cause false marking of a bad channel resulting in ring artifacts; 2) Potential intermittent scout scanning interruption due to angle signal drift caused by external interference; 3) Metal edge overlap of mylar strip in gantry may create sharp edge.…

The metal edge overlap of the mylar strip in the gantry was uneven, which may create a sharp edge.

Two issues were identified with the computed tomography x-ray system including a service function which may cause false marking of a bad channel resulting in ring artifacts, and potential intermittent scout scanning interruption due to occasional angle signal drift.. If these pro…

Two issues were identified with the computed tomography x-ray system including an intermittent issue which may affect image data leading to artifacts; and intermittent scout scanning interruption due to occasional angle signal drift. This may result in the need for rescanning …

In affected software version, of Positron emission tomography and computed tomography system, the CT Hounsfield unit curve may not display in real time when using the bolus tracking protocol with the tracker scan function. If this occurs, the subsequent clinical scanning protocol…

Two issues were identified with the stationary x-ray system. 1. Some position illustrations in the patient exam interface show the incorrect anatomical position for the standard of care. When the image is acquired with the wrong reference position, clinical diagnostic requirement…

Potential sporadic software bugs in R001.3.0.0.750505 software version may cause an issue with the PET acquisition raw data causing reconstruction problems during PET/CT scanning and could possibly cause rescans of patients with additional dose.

X-ray imaging system positioning image and protocol label is reversed for Flexion and Extension on C-Spine and L-Spine, this will cause the image to be incorrectly labeled and may cause the patient to have a repeat exposure.
