Features



With AdvantageSim MD, you can
prepare geometric and anatomical
data for external beam radiation
treatment before dosimetry
planning. Using a set of CT images
of the patient in the proposed
therapy position, you can
automatically or manually define
anatomical volumes.



You can utilize additional CT, MR, or

PET studies co-registered with the
CT scan to assist planning.



For advanced clinical functionality

and flexibility, you can aid the CT
simulation with these available
options:
- Multi-modality target definition
- 4D CT and 4D PET respiratory

review

- A suite of automated and semi-

automated CT-based organ
segmentation tools



You can take advantage of 3D

contour interpolation that lets you
define a full volume contour with a
minimum of 3 contours in
orthogonal planes.



The application lets you define and

manipulate volumes with
automatic thresholding tools,
structure drawing (with or without
Live Wire to pixel value gradients),
and automatic interpolation. Beam
placement is facilitated with the
automatic isocenter placement
and the beam’s eye view (BEV)
features.



The mouse-driven package has an

easy to use, intuitive user interface.

Intended Use

Advantage Sim MD is used to prepare
geometric and anatomical data
relating to a proposed external beam
radiotherapy treatment prior to
dosimetry planning. Anatomical
volumes can be defined
automatically or manually in three
dimensions using a set of CT images
acquired with the patient in the
proposed treatment position.
Definition of the anatomical volumes
may be assisted by additional CT, MR
or PET studies that have been co-
registered with the planning CT scan.
Additionally, CT & PET data from a
respiratory tracked examination may
be used to allow the user define the
target or treatment volume over a
defined range of the respiratory
cycle.
The geometric parameters of a
proposed treatment field are selected
to allow non-dosimetric, interactive
optimization of field coverage.
Defined anatomical structures and
geometric treatments fields are
displayed on transverse images, on
reformatted sagittal, coronal or
oblique images, on 3 D views created
from the images, or on a beam eye’s
view display with or without the
display of defined structures with or
without the display of digitally
reconstructed radiograph.

Regulatory Compliance

AdvantageSim MD complies with the
European CE Marking directive for
Medical Devices 93/42/EEC.



With the touch of a button you can

access pre-defined, configurable
treatment plan templates, load
geometry and field shapes from a
palette of templates, and apply
pre-defined action sequences for
additional ease of use.



Modify contour and field definition

parameters on the fly to tailor
thresholds, margins, and display
characteristics to individual patient
data sets.



Use AdvantageSim MD

independently of the treatment
planning system to increase your
workflow efficiency. The
application can be accessed from
a dedicated workstation, a
networked client computer, or a
compatible scanner console.



You can push completed plans to

an RTP system in standard DICOM
RT format. DICOM RT data can be
received from DICOM RT compliant
systems and re-simulated in
AdvantageSim MD.



You can automatically remove the

couch from the image volume for
even greater efficiency.



The program’s 3D based display

and manipulation features give
you full patient anatomy
visualization.
