Robotic Positioning
Achieving Accuracy
One of the major obstacles to achieving accuracy in the
delivery of radiation therapy is patient positioning and
organ motion. The introduction of Elekta Synergy® and
Elekta Axesse™ minimizes the uncertainties arising from
target motion by providing 3D volume imaging at the time
of treatment, highlighting any positional discrepancies
before treatment begins. This allows clinicians to reduce
margins with confidence, escalate dose and move towards
hypofractionated treatment regimes. HexaPOD™ evo RT
System completes the image guided radiation therapy
(IGRT) localization chain by enabling accurate and remote
geometric correction of any discrepancies observed and then detecting any table movement before treatment.
A Unique Patient Positioning System
HexaPOD evo RT System is a unique fully robotic patient
positioning system with six degrees of freedom to correct
for any misalignments detected by X-ray volume imaging
(XVI) or portal imaging, provided by the Elekta range
of digital linear accelerators. The computer controlled
robotic treatment couch allows six independent degrees of
freedom: x, y, z, pitch, roll and yaw and is able to achieve
submillimeter 6D conformal positioning accuracy.
HexaPOD evo RT System comprises the HexaPOD evo RT
Couchtop, equipped with the new generation homogenous
carbon fiber couchtop – based on the iBEAM® evo
Couchtop and iGUIDE® system – including the camera
tracking system and control consoles, both inside and
outside the treatment room.
Fast and Flexible Cost Saving Tool
HexaPOD evo RT System technology is compatible with a
range of Elekta linear accelerators and, when integrated
with the iGUIDE software, enables fast, flexible and
automated patient set-up. This makes it a time and cost
saving tool for any modern radiation therapy department.
i
iGUIDE® Tracking System and iGUIDE Software
The intuitive user interface of the iGUIDE software uses
clinical workflows to aid the user and supports accurate
positioning of the HexaPOD evo RT Couchtop to the
defined isocenter co-ordinates, relative table position or a
new position based on correctional data received from XVI,
using all six degrees of freedom. The iGUIDE software is
accessible inside and outside the treatment room.
HexaPOD evo RT System can also be controlled manually
by using the handheld control when required.
The iGUIDE Tracking System along with the iGUIDE
software controls the robotic couchtop and validates
the table position. The high-precision camera tracks the
markers on the reference frame in real time, making it
possible to calculate the position of the robotic couchtop
and patient.
HexaPOD™ evo RT System Workflow
HexaPOD™ evo RT System can interface to XVI where image registration is carried out, which provides the table correction vectors required to compensate for any observed organ, or patient movement. All table
correction movements can be remotely performed by HexaPOD evo RT Couchtop and no additional table movements are required to correct for any misalignment.
