dcmconv batch convert

[bernte]

is there a possibility to convert from any (unknown transfer syntax) dicom file into a specific format (VR implicit,Compression none)? For example for batch converting: any inputfile -> specific outputfile.


Thanks in advance

dcmconv allows you to convert any uncompressed transfer syntax (i.e. explicit VR little endian, explicit VR big endian and implicit VR little endian) as well as deflated transfer syntax into a particular uncompressed or deflated transfer syntax. This conversion works reliably as long as the DICOM files are stored according to part 10 (i.e. have a meta header). Otherwise dcmconv tries to recognize the input transfer syntax automatically.

The inputfile should look like the "howitshouldbe" file.

-----------------------------------------------------------------------------------Filename Byte Order Value Representation Compression
-----------------------------------------------------------------------------------
"howitshouldbe" little endian implicit none
"input" little endian explicit JPEG lossless



-----------------------------------------------------------------------------------

dcmconv.exe -f +ti input output
DcmElement: Unknown Tag & Data(4956,3346) larger (1229729838) that remaining bytes in file
Error: Invalid Stream: reading file: input

dcmconv.exe -f -ti +ti input output

1. Your input format "little endian explicit JPEG lossless" is not supported by dcmconv as I wrote in my previous posting.
2. Why are you using option "-f"? This tells dcmconv to read a data set without file meta information.

[bernte]

For example we have a JPEG lossless compressed file, to open it in Efilm 1.53 it must have the following format "little endian implicit".

It is possible to convert it with dcmconv OR do you have another way to do this?

[Jörg Riesmeier]

Use dcmdjpeg.

danke erstmal ich werd das mal testen
