How TGA and DCM differ in practice

TGA can carry an alpha channel and DCM cannot. Transparent areas are composited onto a solid background during conversion, so pick that background colour deliberately: white is the default, and it is rarely the right choice for a logo that will sit on a dark page.

TGA to DCM Conversion: FAQ

What are TGA files?

The TGA (Truevision Graphics Adapter) format, also known as Truevision TGA or TARGA, is a bitmap file containing raster graphics and was initially associated with TARGA and VISTA boards. TGA files can be used on DOS, Windows and Mac OS X platforms for storing and transferring deep-pixel images. They support a color range of up to 24 bits and an 8-bit alpha channel. TGA files are associated with graphic adapters that can capture NTSC and/or PAL video images signals, and they are particularly popular in the domain of still-video editing.

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.
