Question

How to import very large DICOM RTDose files into myQA Patients? Or what to do when I have the message "Array dimensions exceeded supported range."?

Answer

Due to a high resolution in the TPS, DICOM RTDose files can become very large. The following message may appear when trying to import them into myQA Patients:

Here, what needs to be done to be able to still import them:

Step 1

Navigate to C:\Program Files (x86)\IBA Dosimetry\myQA

Step 2

Open IBADos.CSP.Run.Shell.exe.config with permissions to edit it.

Step 3

Add the following line to the <runtime> section:

<gcAllowVeryLargeObjects enabled="true" />

For example like this:

<runtime>
 <gcAllowVeryLargeObjects enabled="true" />
 <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
   <dependentAssembly>
     <assemblyIdentity name="NLog" publicKeyToken="5120e14c03d0593c" culture="neutral" />
     <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
   </dependentAssembly>

Step 4

Restart myQA.
