Hazard: It was determined that under rare environmental conditions (i.e., extremely dry air in combination with a highly isolated floor) electrostatic discharges (ESD) >8 kV may trigger an unintended movement of the AXIOM Luminos dRFsystem which may lead to an emergency situation and pose danger to the patients, operating personnel or to the unit.

Hazard: Potential malfunction due to a software issue for ACUSON SC2000 ultrasound systems using software version 3.5 (VA35) when using the stress echo feature which could cause the need for the study to be repeated.

Hazard: Software issues with ACUSON SC2000 ultrasound with software version 3/5 (VA35) - may incorrectly display the color flow data in the wrong position and when Doppler Frequency is adjusted, the system does not restart the pulsed wave Doppler or continuous wave Doppler waveform.

Hazard: Siemens discovered a processing error for the MAGNETOM Aera magnetic resonance system that may have resulted in some users not receiving Operator Manuals.

Hazard: Siemens Radiation Oncology became aware that customers may be using the Siemens Linear Accelerator in combination with stereotactic accessories which have not been validated as being compatible with Siemens LINAC models.

Hazard: Table may lose calibration during patient treatment, which may cause the possibility of mistreatment.

Hazard: There is a potential and possible hazard to the user when using the MAMMOMAT Inspiration PC monitor at the control desk, in that the holder of the PC monitor can break causing an unstable monitor to fall causing possible serious injury.

Hazard: A complaint reported that the archiving method at one customer site was changed from implicit to explicit, and the cleanup procedure enabled by the explicit archivingmethod may have deleted data from archive itself.

Hazard: Systems with the affected serial number are experiencing a software error which may lead to incorrect patient demographics display.

Hazard: It was observed that the corrugated hose holder above the 3D rail on the Multix Fusion system became loose. According to the Installation Instructions the corrugated hose holder shall be afixed with transversal carriage, with Loctite 243 and Torque 10nm during system installation. Siemens initiated the update instruction to verify and secure the hose holder with Loctite 243. A PCB D802 Rev. 00 b

Hazard: When fourSight 4D ultrasound imaging, 3-Scrape real time 3D imaging, or Anatomical M-mode are used during an Obstetric or Gynecology study, data from the previous patient could replace the current patient's date in the report.

Hazard: There is a potential issue and possible hazard to patients when using the AXIOM Vertix MD Trauma systems. In rare cases, steel ropes inside the lift column of the system can be defective without triggering the safety lock, which can result in the U-arm dropping down unexpectedly during movement in vertical direction, potentially causing serious injury.

Hazard: ACUSON P300 ultrasound systems using the PA230 transducer with a user-defined preset which includes the 100% setting for output power could cause the transducer surface temperature to exceed the maximum allowable limit.

Hazard: An inappropriate cable connection was assembled for certain Artis zee systems. which may cause a system failure and possibly lead to a restricted maneuverability of the gantry system.

Hazard: Certain units of the AXIOM Artis Systems are using a flat detector cooling unit with inappropriate connectors that may possibly leak, causing a system failure and possible drop out of the gantry system.

Hazard: There exists the possibility that during clinical operation, a breakdown of the x-ray tube could result in loss of x-ray imaging for the Artis Q and Artis Q biplane systems with a flat detector as 40 HDR (large 30x40).

Hazard: Potential patient data mixup. Improper error handling could allow for two different patients to be displayed in syngo Dynamics. Images shown for one patient and reporting system shown for a different patient, leading to the potential for misdiagnosis.

Hazard: During the lifetime of Artis zee Ceiling systems, there is an increased wear due to potential sub-optimal cable guidance that can lead to cable damage.

Hazard: During clinical operation, a malfunction may occur causing a system display freeze with SOMATOM Definition, Definition AS, and definition Edge while running software version syngo CT2012 B and syngo CT2013B.

Hazard: The locking mechanism that is intended to hold the control panel in a fixed position can become loose and fail to lock the rotation of the control panel, making it unable to steer or control during transport.

Hazard: The user interface assembly on the ACUSON SC2000 may become loose with the potential for the entire module to fall off of the ultrasound system.

Hazard: Update to correct the possibility for patients or operators to have their fingers trapped or pinched between the table top and the bottom frame of the 550 TxT Treatment Table. Combined with this update instruction is a second complaint issue related to an incident in which a cable inside of the TxT" Treatment Table has been damaged due to contacting a moving part. The resulting short-circuit cau

Hazard: In a very rare occurrence an intended movement of the SimView NT simulation system components could not be stopped with usual hand control or the collision detection functionality.

Hazard: A safety risk regarding a potentially existing dark current radiation phenomenon on the Linear Accelerator (LINAC) in combination with IMRT or mARC (rotational IMRT) treatments using unflat (flattening filter free) beams. In case there are many long periods of field shape changes in a treatment plan, the dose due to dark current radiation may sum up to a significant value.

In case there are many long periods of field shape changes in a treatment plan, the dose due to dark current radiation may sum up to a significant value.

Hazard: A potential malfunction and hazard to patients exists when using the Ysio, Luminos Agile, Luminos dRF, and Uroskop Omnia systems with software version VC10, which may result in radiation continuing longer than required and overexposed images that are not of diagnostic quality.

Hazard: When using systems operating with software versions VD10A/G during a RAD examination, a malfunction can result in radiation continuing longer than required resulting in an overexposed image that is not of diagnostic quality, prompting repetition of the examination.

Hazard: The firm became aware of an unintended behavior when using the syngo.plaza. The "Rename" functionality can cause an unintended patient merge if the patient is sent to another system. This issue affects customers who transfer patient data between two or more syngo.plaza or syngo Imaging XS systems.

Hazard: The firm became aware of a potential issue with Artis zee systems bearing model numbers 10094135, 10094137, and 10094141 equipped with a card collimator from a specific lot where a dislocation of the scatter radiation filter inside the card collimator may occur.
