Directive WEEE
Symbol Meaning Remarks
Location: Near or on
the type identification
plate.
Symbol for separated collection of
electrical and electronic equipment per
Directive 2002/96 of the European
Parliament and the Council of the
European Union (Directive on Waste of
Electrical and Electronic Equipment). If
applicable to the type of device, it
indicates legally imposed obligations
within EU member states, Iceland,
Norway and Switzerland when the
equipment is disposed of, at the end of
its life-time.
Owners of marked equipment should
contact the organization that imported
the equipment into their country, when
they want to dispose of the equipment,
at the end of its lifetime. The Directive
prioritizes re-use of equipment over re-
use of components over re-use of
materials over disposal as waste. Article
5 part 2d allows producers to decline the
return of any used equipment that is or
may be biologically or radiologically
contaminated.

flat panel imaging system and cone beam CT option. This manual contains all necessary instructions
for servicing the specific Oncentra Simulation items. The flat panel and cone beam CT are handled as
an add-on to a "conventional" simulator, and therefore this document has to be used together with the
Simulix-HP/HQ Service Manual.
This manual provides the following information:
•Safety instructions.
•The general and physical description provides an overall introduction to the flat panel simulator.
•Installation instructions for the specific flat panel parts. A short description of the steps that are
required to do the installation of the flat panel parts.
•Methods for adjustments and calibrations.
•A description of preventive maintenance.
•A troubleshooting assistance.

1.4 Simulix Impact
The electronics and software design of the Evolution hardware with Oncentra Simulation software
result in minimal interference with basic simulator tasks. Unexpected failure of the hardware or
software will normally not impair movements of the simulator.
The flat panel detector replaces the image intensifier and the fluoro camera. The Oncentra Simulation
computer and monitor replace the fluoro monitor and the DTI hardware (if installed). The generator
control signals between the simulator and X-ray generator will have to be routed via a dedicated (flat
panel) interface unit. This interface unit controls all timing aspects for the generator and the flat panel
detector. The generator will be modified to produce a pulsed type of fluoro. This means that instead of
a continuous production of X-rays, small pulses of X-ray are produced while the footswitch is pressed.
For cone beam CT, the collimator is modified with a moving cross-wire deck and X-ray reference
detector. A gantry angle unit is installed in the gantry. The zero tray and block tray need to be
adapted. There is new wiring for the collimator, gantry and central cabinet. The interface box is
modified. The generator is modified for CT mode.
1.5 Requirements
1.5.1 Requirements For Upgrade Systems
A Nucletron simulator (type Simulix-HQ or Simulix-HP) can be upgraded to a flat panel equipped
simulator (type Simulix Evolution). The following site-specific requirements must be met:
•EMD Compact 60 or Epsilon RF50 generator.
•Reinforced collimator head.

112.913ENG-04 Simulix-Evolution Imaging – Technical Manual 1-3
•Compact 60 or Epsilon RF50 compatible tube: Dunlee DU694 Tube, Comet DX104 Tube or
RAD 94
An existing CT option cannot be used after installation of the flat panel upgrade. However, a Simulix-
HP/HQ or Simulix Evolution simulator can be upgraded for cone beam CT.
1.5.2 Requirements For New Installations of Evolution Systems
The site preparation as described in the Simulix-Evolution Site Preparation Manual [1] should be
followed.
1.6 Safety Precautions
The simulator is equipped with safeguards to prevent injury to the operator and patient during use and
in case of system malfunction.
For the safeguards of the X-ray generator, please refer to the X-ray generator documentation.
Preventive maintenance is required for the simulator (see Chapter 11).

Term Description
Tag A tag is a generic term for a language element descriptor. The set of tags for a
document or other unit of information is sometimes referred to as “mark-up”, a term that
dates to pre-computer days when writers and copy editors marked up document
elements with copy editing symbols or shorthand. In XML attributes are described by
tags (keywords/identifiers)
The syntax is:
Begin-tagA optional-value End-tagA
Or
Begin-tag-A
Begin-tag-B optional-value End-tag-B
…
Begin-tag-Z optional-value End-tag-Z
End-tag-A
An example:
<Address>
<Street></Street>
<City>Veenendaal</City>
<Country>The Netherlands</Country>
</Address>
This defines 4 attributes:
Address which contains 3 attributes: Street, City and Country
Street has no value.
City has value “Veenendaal”.
Country has value “The Netherlands”

2. General Description
2.1 Context Description
The Simulix-Evolution simulator with the Oncentra Simulation software package is a fully digital image
acquisition, processing and review system. It completely replaces the conventional imaging chain
(image intensifier, camera and fluoro monitor or DTI). The Oncentra Simulation software can be
added to the imaging chain of an existing Simulix-HP/HQ, or integrated with a new Simulix to provide
digital fluoroscopic imaging capabilities (future release). With the cone beam CT option, Computer
Tomography (CT) is available on flat panel systems.
The basic relationship of Oncentra Simulation with the simulator and the X-ray system is shown in
Fig. 2-1. The flat panel imager detects the X-ray transmitted through the patient. The video signal
from the detector is transmitted to the computer at the Oncentra Simulation workstation. The
Oncentra Simulation computer is for image acquisition, image processing, image display and image
review. The computer display serves as the fluoro monitor (as with DTI).
For fluoroscopy, Oncentra Simulation provides image enhancement, image correction, Last Image
Hold (LIH) functions and fluoro image save. The image can be stored on the hard disk together with
the simulator positions and patient data. Acquired images can be retrieved for review and transmitted
to the department network. Image and patient information can be sent to a printer or a planning
system.

2.2 Hardware
2.2.1 Flat Panel
The flat panel imager contains an amorphous silicon detector. The grid and the measuring chamber
are mounted on top of the detector. The detector intercepts X-ray photons, and converts the photon
energy into an electrical image that is subsequently used to create a visible image. This provides
high-resolution images.
The flat panel imager replaces the image intensifier and the fluoro camera.
2.2.2 Interface Unit
The interface unit is responsible for the communication with the flat panel and the computer. It
synchronizes the flat panel, the X-ray generator, Oncentra Simulation and the Simulix.
2.2.3 X-ray Generator
The generator controls the X-ray tube in pulsed mode or CT mode.
2.2.4 Oncentra Simulation Workstation
For a description of the hardware, see Section 3.3.
2.3 Software
For a description of the software, see Section 3.7.
2.4 Operating Procedure
For further information, please refer to the Simulix-Evolution (Oncentra Simulation) User Manual [6].
2.4.1 Oncentra Simulation
As soon as the fluoro footswitch is pressed, the fluoro image will appear in the large window. At the
top of the image, the text “Live image” is visible.
After taking the foot off the footswitch (releasing), the image is “frozen”. At the top of the image, this is
indicated by LIH (Last Image Hold). At the same time the simulator positions are retrieved from the
simulator.
2.4.2 Oncentra ConeBeam
When the footswitch is pressed, the gantry rotates around the patient to acquire a volume of isotropic
Computed Tomography (CT) data.
After this CT-scan, the volumetric data is reconstructed into user-definable slices for patient
verification and treatment planning.
