It has been discovered that there is a possibility that the fixing screws of the ceiling movement gear in the ceiling suspended arm that are part of the X-ray interventional systems may become loose. As a result, ceiling lateral movement may no longer be possible, abnormal noise may be generated from the suspension system and a sensor error may be displayed

There is a potential for formation of ice occurring in the venting system of the superconducting magnet of the MRI systems. if a quench occurs in this condition, helium gas may not be able to escape via the designed vent paths, and the pressure in the helium vessel may rise. This pressure build-up could eventually rupture the helium vessel, causing helium gas to be released into the MR scanning room.

Affected system contains components that do not meet the required distance between electrodes for compliance with the IEC 60601-1 standard for medical electrical equipment.

It has been found that when SPOT Fluoro is first turned on, the default ROI is selected and the collimator blades move to the boundary of the ROI, and the static image is overlayed around the ROI, covering the collimated area. If the customer changes the ROI, the collimator blades and static images are adjusted accordingly. However, when the acquisition program is changed, the collimator returns to the default ROI position which may be larger than the specified one, leaving the X-ray area partially covered by the static image. This is a software problem with the SPOT Fluoro program and will not occur if the function is not used.
