I developed a DICOM protocol analyzer and simulator called DICOM Detective.
Anyone can download it from my website http://www.dicomtool.com and try it.
The serial number is "EVALUATION". Any advice is welcome.

DICOM Detective is a DICOM protocol analysis and simulation software tool
dedicated to PACS maintenance people, DICOM servicemen, programmers,
consultants, radiologists or people working with DICOM networks.
Using the DICOM Detective, PACS maintenance people and DICOM servicemen can
analyze the DICOM communication problem online immediately and DICOM
programmers can simulate the DICOM communication offline and trace and debug
their program without traveling to onsite.
