Hello Santhosh,

Check the transfer syntax of the IOD.
If its compressed, use the corresponding codec.

Hi,

@Ro2a: Sorry for the wrong reply.

@Michael: Thanks for the information.

Meanwhile, in the dcmdump program there is an option to extract the pixel data to file using the +W option.

Code: Select all

dcmdump.exe -d +W d:\output 1.dcm 
Thanks and Regards,
Alvin

I think you are using wrong window width/level for this image.

Try reading the image with setMinMaxWindow function of the DicomImage Class.
