Convert DICOM to CALS

DICOM, or Digital Imaging and Communications in Medicine, is a standardized file format used in the field of medical imaging. It facilitates the storage, exchange, and transmission of medical images and related information between devices from different manufacturers, ensuring interoperability in healthcare environments. Originating from efforts by the National Electrical Manufacturers Association (NEMA) and the American College of Radiology (ACR) in the 1980s, DICOM's evolution has played a crucial role in the development of advanced medical imaging technologies and systems.

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
