Siemens SimView NT and SimView NT with IDI simulation system components:

Siemens became aware of a very rare occurrence where an intended movement of the SimView NT simulation system components could not be stopped with usual hand control commands or by use of the collision detection functionality. It is possible that simulation system components could collide with patient and/or system equipment.

SIMVIEW NT and SIMVIEW NT with IDI:

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.

AdvantageSim MD versions 7.4 through 7.6, Model 5160092-2 Version 7.4, 5160092-3 Version 7.5, 5160092-4 version 7.6.

It was reported by a customer site that when using GE AdvantageSim MD on Advantage Workstation, the series could be incorrectly labeled in image view when multiple series of an exam are loaded simultaneously in Advantage Sim MD and if their series dates are different. A mismatch of series label for structure sets may lead to under-treatment of a tumor due to too small coverage of volume treated.

Drive Belt for Radiation Therapy Simulation systems SIMVIEW 3000 and SIMVIEW NT with CT option or IDI.

Excessive wear on drive belts used for Image Intensifier and/or X-ray head drive mechanisms may result in uncontrolled movement, which may cause injury.

Acuity with Conebeam Computed Tomography; Radiation therapy simulation system; Model Number: H77.

Incorrect Image Orientation: The image orientation tag may not be set correctly if the patient has been scanned with an orientation other than Head First Spine. When such images are imported to a treatment planning system, they may appear with either a mirrored or a rotated view.

Update Instructions "TH003/08/S" applies to Siemens brand SIMIVIEW 3000, SIMVIEW NT, and MEV ASIM S systems;

The firm sent an Update Instruction, "TH003/08/S" for Motion Enable Switch/holder assembly. The switch holder allows the motion enable switch to be activated if inserted partially; thereby enabling inadvertent motion and serious injury may result.
