Hi Marco, Thanks very much for your reply. The problem that I find is that it only works for a remote device that are known within the network. My goal is to use a TLS connection in which a certain sender or receiver are outside of the network. What's the standard way of connecting into an unknown r...

TLS Connection: truly secure?

Hi, I am using the DICOM toolkit to send images across a network using a TLS connection. The images were sent and received successfully only if both the sender and receiver have the same certificate. When the sender and the receiver have different certificates, it fails. The latter method works when...

Encryption question using dcmtk 3.5.4

Hi, I'm using storescu and storescp to send and recieve images using a secure connection. I looked at the options to use that type of connection. What is the difference between a secure connection with an authenticated certificate and a secure connection without it? Which secure connection is less v...

Hi Jorg, Thanks for your response. In general, I'd like to just compress the DcmFileFormat object in memory, then immediately transfer the object. I find that if I load the uncompressed file, run the compression routine, save the file, then reload it, yes it is then interpreted as a compressed image...

The chooseRepresentation() function did do the compression but the problem that I find is that the transfer syntax is not getting in the dicom dataset itself until it is directly saved into file. I tested with this code. dataset->chooseRepresentation(opt_oxfer, rp); DcmXfer original_xfer2(dataset->g...

Sending image from memory

Hi,

Is it possible to compress the image in memory the image object? In dcmcjpeg function where does the actual compression take place? Is it possible to save the file object to memory as opposed to directly to disk via saveFile()?

What methods should I use?

Thanks very much. It was really helpful. Here's another question: Is it possible to lose any kind of data when compressing and then decompressing the DICOM image? I compared the original with the compressed image that was decompressed and the images matched with every single pixel. I used the dcmcjp...

storeSCU and storeSCP compression

Hello, I want to take an uncompressed DICOM image, send it out compressed, and then the receiver decompresses the image. My question would be is using storeSCU the right way to do this? and does storeSCP accept receiving the image that way? If yes, then how? I am only interested in lossless compress...
