How to Use DICOMan to Put TOMO Dose Matrix into Pinnacle3 RTP
DISCLAIMER: LICENSEE ACKNOWLEDGES AND AGREES THAT UAMS DOES NOT ASSUME THE RISK OF LICENSEE'S CONSEQUENTIAL OR
INCIDENTAL DAMAGES WHICH MAY ARISE IN CONNECTION WITH LICENSEE'S USE OF THE SOFTWARE AND DOCUMENTATION. YOUR
PROFESSIONAL DISCRETION IS ADVISED.
This material is made exclusively to complement the section “3.7.8.8 Export to Pinnacle” of “DICOMan User’s Guide” which
is included in DICOMan software package. There are three software systems involved in this RTDOSE IMPORT process:
TomoTherapy® Planning System, DICOMan© and Pinnacle3® RTP system. This material details configuration procedures
for the involved systems.
I. CREATE A DIRECTORY FOR RTDOSE IMPORT ON PINNACLE WS
1. Create a directory under /home/p3rtp
Open a UNIX terminal, at the prompt, enter this UNIX command: mkdir TomoDM
2. Get the IP address of your Pinnacle Server
In the UNIX terminal, at the prompt, enter this command: ifconfig -a
Figure 1 Retrieve the IP address of your Pinnacle Server. The number string after “inet” is the IP address which is needed
at the step to transfer dose matrix files (see Figure 10).
II. START DICOM STORAGE SERVER IN DICOMAN AND ADD DICOM
ENTIRY ON TOMO SIDE
1.
Select main menu item “File >> Storage Server”.
2.
Set up parameters for DICOMan DICOM storage server. Figure 2 shows one example.
3.
Add a DICOM entity in TOMO system. Make sure the setting on TOMO side (Figure 3)
matches the setting of DICOMan (Figure 2).
Figure 2 Setting up DICOM storage server.
Figure 3 Add a DICOM entity on TOMO to match the setting
on Figure 2.
Note: If user prefers to use other storage server, make sure both settings match.

Figure 4 The message window in the bottom-left corner indicates that the build-in storage server is on. It also shows
monitoring messages when it receives incoming objects.
III. EXPORT RTDOSE FROM TOMOTHERAPY
Figure 5 Export RTDOSE from TomoTherapy Planning Workstation. “Opt_Dose_After_EOP” is the item to be
exported.
Note: There is an interlock in TomoTherapy system that no item of currently open patient can be
exported.
WARNING: There is an anomaly in the●ART
HI software regarding DICOM Dose Export.
Furthermore, the error is limited to only patients scanned in a feet first orientation. When the
exported dose is imported to any 3rd party software application, the dose will be inverted
longitudinally (i.e, by 180°) in that 3rd party software application. Product Affected: Software
versions prior to versions 3.1.4 and 3.2.2 that include the DICOM Dose Export option.
Since TomoTherapy Inc. is aware of that issue and plans to fix it, DICOMan is not going to rotate
the RTDOSE matrix. DO NOT USE IT FOR FEET-FIRST CASES.

IV. READ, VIEW AND CONVERT RTDOSE WITH DICOMAN
1.
Read TOMO RTDOSE object by clicking this global button with folder icon
select the RTDOSE file in the file browser as shown in the figure below.
, and
Figure 6 Find the RTSOE file using a file browser. The DICOM storage server will create a folder (named in
combination of patient’s name and ID) for each patient in the DICOM staging folder, C:\DICOMan\stage as
shown in Figure 2. The received TOMO RTDOSE file is something like RD.1.2.826… as shown in this figure.
2.
View RTDOSE object to make sure that it is the right one
Figure 7 View RTDOSE in DICOMan. User can use “Value-At-Cursor” function to view dose values at cursor.
3.
Convert it to Pinnacle dose matrix format and transfer generated files to Pinnacle
In the tree window on the left, right click on RT DOSE item and select “Export to Pinnacle”
menu item as shown in Figure 8.
3
Figure 8 Select the pop-up menu item of RTDOSE object in tree window.
4.
Decide whether to create a composite plan (dose summation) or a separate trial (plan
comparison)
Figure 9 Decide what to do.

5.
Verify the setting for FTP
Figure 10 Verify the FTP setting. The setting will be saved for later use. Make sure that the remote folder
on Pinnacle side has to be in full path.
Note: a directory “TomoDM” which accommodates TOMO dose matrix and script files
should be created in advance on Pinnacle server (see Step I above).
6.
Transfer converted files to Pinnacle (click OK button in Figure 10)
Figure 11 The message window of FTP process.
Please make sure that three files will be transferred to Pinnacle:
1.
DisplayTomoDose.Script, – the primary Pinnacle script to put TOMO dose matrix;
2.
plan.Trial.binary.001 – the converted TOMO dose matrix in Pinnacle format;
3.
LoadTomoDose.Script – the secondary script to reload TOMO dose matrix after dose matrix’s position is adjusted.
5
Note: Dose matrix is usually a large file. It may take up one minute to complete data transfer
depending on your local network setting. If it takes unreasonably long time, the user is advised to
check the duplex status of network card. Full duplex is strongly recommended if possible.
V. MAKE A COMPOSITE PLAN OR A COMPARE TRIALS ON PINNACLE
1.
Create a hot script button “Import TOMO Dose” in the sent Pinnacle script
“/home/p3rtp/TomoDM/ DisplayTomoDose.Script”
2. Create a hot script button “Reload TOMO Dose” in the sent Pinnacle script
“/home/p3rtp/TomoDM/ LoadTomoDose.Script”
3. Open the patient and make sure that the dose matrix of the Pinnacle plan includes the whole
image volume and recalculate the dose distribution.
4. Run the first script.
5. Check the alignment of dose matrix. If it is off a bit, adjust the alignment and run the
second script.
TIP: What the first script does is first to delete TOMO beam “_tomobeam” if there was one, and
remove TOMO prescription “_tomoprs” if it existed; and then add new “_tomobeam” and
“_tomoprs”. The preceding underscore is intentionally added to avoid accidently deleting user’s
beam. If one wants to add two TOMO matrices together, one should simply rename the first
“_tomobeam” and “_tomoprs” and run the hot script again after the second dose matrix has been
transferred.
Figure 12 and 13 show one example before and after a composite plan is created on Pinnacle using
exported TOMO dose matrix.
Figure 12 Pinnacle boost plan after TOMO treatment.
Figure 13 Example of dose summation.

Final comments:
1.
Since version 3.0.0, DICOMan can sum up by itself dose distributions from different
modalities.
2.
The hot script buttons only have to be created once.
3.
If the user is going to create a composite plan, the dose matrix for Pinnacle beams has to
include whole image set (TOMO does that way).
4.
The best result will be achieved if the same CT data set is used for both TOMO plan and
Pinnacle plan.
5.
For the case that Pinnacle plan and TOMO plan were developed on different imaging sets,
you may have to reproduce the Pinnacle plan as precisely as you can on the same imaging
set of TOMO plan (it does not have to be down-sampled) and then perform image
summation procedure.
