How to make presentationLUTData

[m-ishihara]

Hi forks,

I am not the person who sent this question originally.
But I have a very simple and important problem.
So, I would appriciate it if someone answer my question.

I am tring to implement to apply PresentationLUT data from outside of the DICOM file to the DICOM image.
But I don't know how to make the PresentationLUT data with DcmUnsignedShort.
Once I tried to make DcmUnsignedShort data, as follows;

unsigned short *ee = new unsigned short[8];
ee[0]=0;
ee[1]=1;
ee[2]=2;
ee[3]=3;
ee[4]=4;
ee[5]=5;
ee[6]=6;
ee[7]=7;

DcmUnsignedShort *data;
data = (DcmUnsignedShort *)ee;

But the "data" which come as a consequence weren't the intended data.
Please tell me how to make the DcmUnsignedShort data from unsigned short data.

Thanks,

The little tool "dcmmklut" shows how to create presentation LUT data and add the required attributes to a DICOM file.

Hi Jörg,

Thank you for your help.
BTW, I tried to make the source code to put PresentationLut made by user into the DICOM image.
The sample program is as follows;


//PresentationLut
DcmUnsignedShort *presentationLUTDescriptor = new DcmUnsignedShort(DCM_LUTDescriptor);
DcmUnsignedShort *presentationLUTData = new DcmUnsignedShort(DCM_LUTData);
presentationLUTDescriptor->putUint16(1);
presentationLUTDescriptor->putUint16(1);
presentationLUTDescriptor->putUint16(16);
presentationLUTData->putUint16(1);
dcmimage->setPresentationLut(*presentationLUTData, *presentationLUTDescriptor);


Is this code OK?
If there is something wrong, please let me know.

Thanks,

Hello DICOM @ OFFIS,

Thank you for your help everyday.
BTW, I recognized that the source code I wrote yesterday was wrong and found out the correct coding to apply PresentationLut.
So, I don't need more reply for this issue.

Thank you very much for your help!
