1. Download and Install reaConverter
Download reaConverter and install it in seconds. The setup is straightforward — no complex configuration, no extra software required. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your FITS files
Add your FITS files to reaConverter. Whether it's a handful or an entire archive, the batch engine processes them efficiently.
Browse for files, drag them in, or add entire folders at once. reaConverter queues everything automatically.
3. Select DCM as output format
Pick DCM as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.
4. Start FITS to DCM conversion

When the batch finishes, your DCM files are ready in the destination folder you chose earlier.
FITS to DCM: what carries over and what does not
FITS stores 32-bit greyscale covering the full dynamic range of the scan, and DCM 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. FITS carries 32 bits per channel and DCM carries 16, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to a 16-bit format only at the very end.
