MRIcroGL is a Free DICOM and NIfTI images Viewers

MRIcroGL is a cross-platform tool for viewing DICOM and NIfTI images, with a drag-and-drop interface and scripting language. It requires OpenGL 2.1 by default, but can also be compiled for OpenGL 3.3 Core or Metal for macOS users.

If OpenGL 2.1 is not supported, MRIcron can be used. The tool can be compiled for macOS, Linux, or Windows, and supports both ARM-based Apple Silicon and Intel-based computers on macOS.

MRIcroGL uses NIfTI as its native format. However, you can drag-and-drop files of various formats and the software should automatically detect and load these images.
