How to do it

Questions about DICOM to PDF
- Why does browser-only matter so much here?
- Because a DICOM file is not just a picture. The patient name, ID number, birth date, hospital and referring doctor are all stored inside it. Uploading one to a website means uploading a patient identity — which is why this tool reads the file without ever reaching us and sends nothing anywhere.
- My file was refused because of compression.
- It uses JPEG 2000 or JPEG-LS, and no browser ships a decoder for either. Uncompressed, JPEG, JPEG Lossless and RLE files all convert. For those two we could try to decode approximately and hand you something that looks like a scan; in a medical image that is worse than refusing. Ask the hospital for an uncompressed export, or open it in a DICOM viewer.
- Why does the image look different from the hospital screen?
- It should not, and the reason is windowing. A CT scan stores far more brightness levels than a screen shows, and the file itself records which range a radiologist looks at. That range is applied here. If the file does not record one, the actual range of the data is measured and used instead.
