Support
1

Dear sir,

Please find the attached file to find out the cause of error. I can’t able to do volume rendering, the software gets closed off itself when i click the eye icon in volume rendering.

I am using Dell Precision core i7 workstation with 16 GB Ram, 2.25 GH processor with in built graphic card and Windows 7 Professional. Please Help me with this issue.

Thanks and Regards

Manoj Bagare

Does volume rendering work with the MRHead sample data set (available in Sample Data module)?

What graphics card and CPU do you have?

Is there any error or warning message in the application log? After you open in the menu: Help/Report a bug, find the previous entry in “Recent log files” list, click “Copy log messages to clipboard”, then paste the log text here.

Please follow the existing conversation instead of reposting the original question.

We cannot see the useful part of the log, because your screenshot only shows the beginning, and errors are expected to show towards the end. Please open in the menu: Help/Report a bug, find the previous entry in “Recent log files” list, click “Copy log messages to clipboard”, then paste the log text here.

Also please provide details about the CPU and GPU you have.

I’d like to add that your screenshot shows that you tried using CPU rendering. If you have a decent graphics card, then you should switch to GPU volume rendering.

Dear sir,

Please find the attachment for the files that i need to work on volume rendering. Please help me to find the solution to the problem.

(Attachment 3DSlice1.dcm is missing)

(Attachment 3DSlice2.dcm is missing)

Thanks for the log! It does not show any errors. Please confirm that this is from a session where it crashed.

What happens if you load the MRHead volume in the Sample Data module and try to render that?

8

Yes. volume rendering is working with the MRHead sample data set.

9

Your attached files did not go through. Please upload them to Dropbox/OneDrive/Google Drive and share the link.

10

The rendering of MRHead sample data is successfully done. But i can’t render my files.

11

Could you upload any of your failing data sets somewhere and copy the link here?

Dear sir,

Please click on the below link for the dicom files. I am not able to do volume rendering for this dicom files.

Dear sir,

Can you please tell me the steps to carry out till volume rendering. I installed software newly in my pc and I am not getting what setting i am missing. Please help me by sending steps to carry out volume rendering.

15

Loading and volume rendering worked perfectly for me, too (Slicer-4.10.2, Windows10, NVidia GeForce RTX 2080). I drag-and-dropped the two folders to the application screen, accepted the offer to import them as DICOM, loaded using DICOM module, and visualized using volume rendering module, GPU volume rendering method.

16

After you import your DICOM sequence, switch to volume rendering module, click on the eye icon, and then adjust the transfer function. That’s all there is to it (at least for me).
