Reading Elekta Synergy MLCi2 Log Files

[thanhtaiphys]

Dear all:

I hope this message finds you well. I am currently working with an Elekta Synergy MLCi2 system, and I need some assistance regarding the Elekta log files.

My system only exports log files in the .dat format, whereas I have learned that some other Elekta models can export log files to the .trf format, which can be read and analyzed using the pylinac library.

I would greatly appreciate any support or guidance on the following:

(1) How to read .dat files using pylinac or any other tools/methods that might work. @jrkerns

(2) Is there a way to convert .dat files to .trf files for analysis.

If anyone has experience dealing with this issue or knows of a solution, I would be very grateful for your insights.

Thank you in advance for your help!

Best regards,
Duong

This might be possible with pymedphys... I know it works for Agility MLC.

Hi Marc @mchamberland

What kind of logfile you are using? As I know, Agility MLC can export to .trf files. We don't have issue with .trf files

[mchamberland]

Hmm... it's been a long time. Let me check.

[mchamberland]

Ah, indeed looks like only .trf format.

Then, maybe look into RadCalc. It has an Elekta MLC module. Not sure what format it supports.

I know it connects directly to the iCom so it can monitor delivery. Not sure about retrospective log file analysis.

Yes, Thank you!
I did a quick Google search, and it seems like everyone primarily works with the .trf format for Elekta logs. It looks like using the .dat format is quite uncommon.

We have been following the same export procedures for both the Elekta Agility MLC and the Elekta Synergy MLCi2. However, while the Agility MLC exports the log files in the .trf format, the Synergy MLCi2 outputs them as .dat files. Therefore, we are unsure how to read these .dat files or if there is a way to export or convert the .dat files to .trf format for analysis with pylinac
