Display of egsphant file

[subha18]

I am having trouble in viewing of the egsphant file, created from the DICOM images using CTCREATE. I tried with egs_view and VICTORIA both they look distorted. Can not make out anything out of it. However the dose calculations using the egsphant file is fine.

How can i generate similar egsphant file along with the contours like the one PeppaBreastHDR192Ir_MBDCA-WG.egsphant supplied with the distribution of egs_brachy code.

Can you post a screenshot and perhaps the file, or at least the beginning of the file (the part with the media and voxel definitions at least).

Thanks you very much for your quick response.

Attached are the egsphant file and the display images

I have seen that before. I can't remember what causes it now...

Are you still using egs_brachy? If so, could you try creating your egsphant using eb_gui instead of ctcreate? It can be downloaded from GitHub here.

Hi Marc,
I have truncated few slices to reduce the file size below so that i can upload it here. Yes, dose calculations are done in egs_brachy which is fine only viewing the phantom is an issue.

What's the resolution of the DICOM CT data? If it is not 512x512, you may need to adjust MAX_CT_COL_SIZE in HEN_HOUSE/omega/ctcreate/ReadCTDICOM.c and $CTJMAX in ctcreate.mortran.

Thanks for the reply.
Yes it is 512 x 512 with few slices. Even if i created the egsphant file using all the slices it looks similar in egs_view as well as in VICTORIA.

I was wondering how can i generate similar egsphant file containing the contours like the one PeppaBreastHDR192Ir_MBDCA-WG.egsphant supplied with the distribution of egs_brachy code. I believe it is not possible using ctcreate.

Try using eb_gui.

Can you post the output text from ctcreate here?

I have not yet tried with eb_gui. Will try

Thanks
