The saved image file is inconsistent with the source file. about dcmjs HOT 9 CLOSED

Thanks for posting this issue with a link to the data. Perhaps someone will be able to use this to help with this.

It would help if you provided the exact code to replicate the issue, along with screenshots before and after. If there are any diagnostic messages printed please include those too.

I used your nodejs sample code.

Did you look at the object before and after? Probably there is a sequence that didn't get converted.

Note that this is not a paid project with guaranteed support. We'd like to make the software better but we need to share the work of investigating any issues. It would help if you posted the file before and after and also investigate specifically what's different.

Here is my code.

const filePath = 'a dcm file path';

let arrayBuffer = fs.readFileSync(filePath).buffer;

let DicomDict = dcmjs.data.DicomMessage.readFile(arrayBuffer);

const dataset = dcmjs.data.DicomMetaDictionary.naturalizeDataset(DicomDict.dict);

console.log(dataset);

DicomDict.dict = dcmjs.data.DicomMetaDictionary.denaturalizeDataset(dataset);

let new_file_WriterBuffer = DicomDict.write();

fs.writeFileSync('to local path', new Buffer(new_file_WriterBuffer));

Thank you for your reply, in addition, I also found that the data parsed by dcmjs will be partially missing.

Sorry for my mistake, I found the reason and I will close this issue.

Okay, glad you sorted it out and thanks for looping back to report here 👍

The reason for this issue is that calling naturalizeDataset and then calling denaturalizeDataset will lose some tags.

Did you see anything odd about the data that would explain why it behaves this way?
