OVERVIEW
The CIRS 6DOF ISO Base, Model 023-08 is an optional accessory of ISO Cube. It is
designed for positioning and leveling of ISO Cube and quick calculation of complex 3D
shifts of RT treatment systems with an integrated robotic couch.
There are two milled pockets on the CIRS 6DOF ISO Base. The ISO alignment pocket
can be used to position and level the ISO Cube™ on the treatment couch. It contains a
set of four Tungsten spheres that are used by ISO AnalyzeTM Software to calculate the
actual Pixel Size for both the MV and kV image detectors.
When positioned in the shifted 6DOF pocket, internal structures of the ISO Cube allows
for the calculation of rotation and translation shifts. The shifted 6DOF pocket is ma-
chined with the mechanical limits of commercially available couches in mind, which can
correct for Pitch, Roll and Yaw of +/- 3 degrees of rotation. The 6DOF pocket is rotated
within the IEC 61217 Coordinate System, +1.5º about X-axis, +2.0º about Y-axis and
+2.5º about Z-axis and translated -15 mm on X-axis, +25 mm on Y-axis and -2 mm
on Z-axis. The translations about the X, Y and Z-axes are applied with respect to the
ISO center of ISO Cube. Having rotational shifts smaller than the mechanical limits of
the robotic couches allows the user to determine if there are errors on either side of the
induced shift.
Both the ISO alignment pocket and the 6DOF pocket are CNC machined in a single
setup.The 6DOF ISO Base is also assembled as a single piece to minimize cumulative
assembly errors.
Note: Feet are adjustable, but not removable.

USE OF THE 6DOF ISO BASE™
To check the 6DOF shifts the following procedure is recommended:
1. Acquire Image Reference Set
Align the ISO Cube to the imaging system that is to be used to acquire the image refer-
ence set. To do this, place the ISO base on the couch of the imaging system (CT) and
register it to an indexing bar. Use a high quality spirit level and level it. Place the ISO
Cube in the ISO alignment pocket.
2. Transfer Reference to R&V
Once the reference image set is acquired, the user can make a plan, simulation CT and
DRRs based on it and transfer them to the R&V software suite for creation of a daily
imaging QA patient.

3. Daily QA Shifts Setup
For daily QA checks of the DOF shifts the 6DOF ISO base is registered to an index-
ing bar of the Linac couch and leveled. The ISO Cube is then placed in the ISO
alignment pocket and the whole assembly is aligned to the Linac’s light field and la-
sers by translating only the couch about the orthogonal axes. Providing that the MV
and kV pixel size is to be calculated acquire the corresponding planar images that
were defined in the ISO Analyze software for these two parameters. Remove the
ISO Cube from the ISO Alignment pocket and carefully place it in the 6DOF shifted
pocket. Make sure the ISO Cube rest firmly against the bottom of the 6DOF shifted
pocket and against the sides of the deepest corner of this pocket.
4. 6DOF Shift Calculations
Apply the translational shifts on each axis with the opposite value shown on the
6DOF ISO Base and then rotate the couch -2.5º about Z-axis, -2º about Y-axis and
-1.5º about X-axis. Take images of the ISO Cube and perform 2D/3D kV/Mv image
matching. The difference between zero and the actual values for each individual
shift shown after 2D/3D kV/Mv images match should be within the setup toler-
ances.

RETURNS
If you are not satisfied with your purchase for any reason, please contact your local
distributor prior to returning the product. Visit https://www.cirsinc.com/distributors/
to find your local distributor. If you purchased your product direct through CIRS,
call Customer Service at 800-617-1177, email [email protected], or fax an RMA
request form to 757-857-0523.CIRS staff will attempt to remedy the issue via
phone or email as soon as possible. If unable to correct the problem, a return
material authorization (RMA) number will be issued. Non-standard or “customized”
products may not be returned for refund or exchange unless such product is
deemed by CIRS not to comply with documented order specifications. You must
return the product to CIRS within 30 calendar days of the issuance of the RMA. All
returns should be packed in the original cases and or packaging and must include
any accessories, manuals and documentation that shipped with the product. The
RMA number must be clearly indicated on the outside of each returned package.
CIRS recommends that you use a carrier that offers shipment tracking for all
returns and insure the full value of your package so that you are completely
protected if the shipment is lost or damaged in transit. If you choose not to use a
carrier that offers tracking or insure the product, you will be responsible for any loss
or damage to the product during shipping. CIRS will not be responsible for lost or
damaged return shipments. Return freight and insur-ance is to be pre-paid.
