DVH

[MohHu]

Dear developer,

When I try to compare DVHs of two plans, one DVH of a structure run without problem, but another is not displayed and mean, min and max dose are always 0.5 Gy as in the attachment below.

Is there any suggestion to overcome this problem?

Yours sincerely

It looks like the dose might not be aligned with the scan or the structure you are analyzing. Couple of checks: (1) verify the dose overlay from the viewer (2) how was dose imported? Maybe the grid alignment was incorrect.

Thanks for your prompt reply, 1- It seems to be there is no problem in the dose overlay as in the link below. 2- I selected ''DICOM'' format, and then went to the ''Go''. In the directory of DICOM files, I chose the directory that contains files of scan, structure and dose. Therefore, it was converted to CERR format.

Any chance you can share anonymized dicom?

Yes, of course,

They have just been sent to your email.

The two plans are not aligned as seen in the attached image. These will have to be registered, followed by dose deformation and then calculate DVH.

On further investigation, it seems there is a bug. If the two plans contain a structure with identical name, then the first occurrence gets picked even when selecting the second occurrence from the DVH GUI. I will fix and let you know when it is pushed to GitHub.

This issue is now fixed and pushed to https://github.com/cerr/CERR. Please try out and let me know in case of any issues.

Dear Dr. Aditya,

Thank you very much dear for your efforts,

I pulled the CERR toolkit, and it is working very well.

Actually, now I am trying to use ''gamma analysis'', but gamma analysis also has errors as shown below:

Error using image NaN is not supported. Error in imagesc (line 52) hh = image(varargin{:}, 'CDataMapping', 'scaled'); Error in CERRColorBar (line 158) ud.handle.colorbarImageH = imagesc([.5 .5], [upLim-margin lowLim+margin], cB, 'parent', hAxis, 'hittest', 'on', 'buttondownfcn', 'CERRColorBar(''ColorbarAxisClicked'')','Tag',tag); Error in CERRColorBar (line 65) CERRColorBar('INIT_HANDLES', hAxis); Error in CERRRefresh (line 107) CERRColorBar('init', stateS.handle.doseColorbar.trans); Error in sliceCallBack (line 3589) CERRRefresh Error in createGammaDose (line 73) sliceCallBack('selectDose', num2str(newDoseNum)); Error in CERRGammafnc (line 262) createGammaDose(baseDose,refDose,structNum,doseDiffIN,DTA,... Error while evaluating UIControl Callback.

Looks like the dose contains NaN. Can you please change NaN to 0 as follows and re-run the gamma calculation:

nanIndV = isnan(planC{indexS.dose}(doseNum).doseArray); planC{indexS.dose}(doseNum).doseArray(nanIndV) = 0;

Thank you for your reply,

I used the code for both plans as following, but the error is still the same.
doseNum = 1; indexS = planC{end}; nanIndV = isnan(planC{indexS.dose}(doseNum).doseArray); planC{indexS.dose}(doseNum).doseArray(nanIndV) = 0;

[adityaapte]

The resulting gamma has NaNs for the part of the image that is not included in calculation. However, the viewer complains about it while displaying gamma. A temporary workaround would be to change NaN gamma values to numeric type.

nanIndV = isnan(planC{indexS.dose}(end).doseArray); planC{indexS.dose}(end).doseArray(nanIndV) = 0;
