SI to DCM Conversion: FAQ

What are SI files?

The SI format is associated with Softimage, a program first released in 1988 for Silicon Graphics workstations. The software specialized in creating 3D animation for the film, broadcasting, gaming and advertising industries, and by 2000 it was replaced by an upgraded version called Softimage XSI. SI images are currently considered rare and obsolete.

What are DCM files?

A DCM file is a DICOM file, meaning it follows the Digital Imaging and Communications in Medicine (DICOM) standard for storing, transmitting, and managing medical imaging data. This standard ensures interoperability between medical imaging equipment and software, allowing images to be shared across scanners, servers, workstations, and network systems.
