Technical note

DICOM to ICO: what to expect from the conversion

DICOM stores 16-bit greyscale covering the full dynamic range of the scan, and ICO shows 8 bits. The conversion applies a window level, so what ends up visible depends on the window you choose. Decide separately whether patient metadata should be copied to the output or stripped from it. ICO stores a limited palette rather than full colour, so the conversion has to reduce the number of distinct colours. Photographic content shows this as banding, while flat graphics and icons usually survive it untouched.

Smart Workflow

Do more with your DICOM files

Converting DICOM files for easier viewing/sharing? reaConverter offers many additional ways to process DICOM images, so you can customize them according to your requirements.

Our range of editing options includes such image processing actions as Adjust Brightness/Contrast for better clarity, Rotate, Crop, Watermarks to stamp resulted images with DICOM Metadata such as Patient Name, Birthday, Acquisition time and more.

Additionally, opting not to copy metadata ensures that patient information is excluded from the output, helping to protect sensitive data and keep the image anonymous.

As someone working with medical imaging on a daily basis, I needed a reliable solution to convert DICOM files into accessible formats for reports, presentations, and interdisciplinary sharing. reaConverter exceeded expectations. It preserves the integrity of the original image data while offering customizable output settings — crucial for maintaining diagnostic quality when converting to JPEG, PNG, or TIFF. What sets it apart is the automation: I’ve configured the Watch Folder to monitor our PACS export directory, so new scans are automatically processed and stored in patient-specific folders. It’s fast, accurate, and has significantly improved our post-processing efficiency.
