The value in the CSV file output by plastimatch dvh is 0 when adding --input-ss-list

[Rex Reynolds]

Hi all:

    I tried latest plastimatch dvh, but got some problems.

    plastimatch dvh --input-dose RTDOSE.dcm --input-ss-img RTSTRUCT.dcm --output-csv dvh.csv

    got Could not create IO object for reading file RTSTRUCT.dcm. Then I tried

    plastimatch convert --input RTSTRUCT.dcm --output-ss-img rs.mha

    plastimatch convert --input RTSTRUCT.dcm --output-ss-list ss.txt

    got rs.mha and ss.txt

    plastimatch dvh --input-dose RTDOSE.dcm --input-ss-img rs.mha --input-ss-list ss.txt --output-csv dvh.csv

    got a dvh.csv with structure names but 0 values.

    plastimatch dvh --input-dose RTDOSE.dcm --input-ss-img rs.mha --output-csv dvh.csv

    got a dvh.csv  without structure names but not 0 values.

    I uploaded the dvh results and sample data.

Another problem, the dvh_has_name.csv is one column less than the dvh_no_name.csv

Can someone help me? 

There's another question. Can I get Dmean of each structure from plastimatch?

Hi Rex,

Sorry for the delay.  The dvh has not been updated to work with DICOM.  I created a ticket for this:

https://gitlab.com/plastimatch/plastimatch/-/issues/76

The workaround is to make plain image files:

plastimatch convert --input dicom/ --output-dose-img dose.mha --output-ss-img ss-img.mha --output-ss-list ss-img.txt

And then run dvh command:

plastimatch dvh --input-dose dose.mha --input-ss-img ss-img.mha --input-ss-list ss-img.txt 

To get a mean, use the --differential option.  Then multiply the fraction by the dose, and sum them in LibreOffice or Excel.  If there is a more convenient format for yielding the DVH output I am interested in hearing opinions on this.

Hi Greg,

    Thank you for your reply. 

    I tried the two following commands(RTDOSE.dcm and RTSTRUCT.dcm are in dicom/)

    plastimatch convert --input dicom/ --output-dose-img dose.mha --output-ss-img ss-img.mha --output-ss-list ss-img.txt

    plastimatch dvh --input-dose dose.mha --input-ss-img ss-img.mha --input-ss-list ss-img.txt --output-csv dvh.csv

    but still got a dvh.csv with structure names with 0 values.

Hi Greg:

    Thank you for fixing this bug. I'll try later.

Hi Greg:

    Sorry for the delay.

    I tried the latest version plastimatch with the sample data but still got the same result:

    plastimatch convert --input RTSTRUCT.dcm --output-ss-img rs.nrrd

    plastimatch convert --input RTSTRUCT.dcm --output-ss-list ss.txt

    plastimatch dvh --input-dose RTDOSE.dcm --input-ss-img rs.nrrd --input-ss-list ss.txt --output-csv dvh0.csv

    got a dvh0.csv with structure names but values are all zeros.

    plastimatch dvh --input-dose RTDOSE.dcm --input-ss-img rs.nrrd --output-csv dvh1.csv

    got a dvh1.csv with values but structure names are all unknown.

    I want to get a dvh.csv with structure names and values.

Hi all:

    Did I do anything wrong or can someone tell me what to do?
