G3N to DCM Conversion: FAQ

What are G3N files?

G3N files contain digitally archived documents that were sent or received using Imaging Fax, a currently obsolete application that allowed computers equipped with modems to communicate with independent fax machines. Such images are stored using Group 3 compression, which provides an optimal minimisation of file size through a line-by-line compression of text and helps effectively compress white space. Group 3 compression was superseded by Group 4, providing a lossless compression of black-and-white images. G3N files are now considered uncommon.

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. DCM files are most commonly used in hospitals, clinics, and private medical practices that rely on medical imaging equipment such as CT, MRI, and ultrasound devices.
