Convert DCM to CALS

DCM, short for Digital Imaging and Communications in Medicine, is a file extension used for medical imaging data. Originating from the DICOM standard developed by the National Electrical Manufacturers Association in collaboration with the American College of Radiology in the 1980s, it facilitates the storage, transmission, and management of medical images and related information across various devices. Its uses span hospitals and clinics, where it integrates imaging modalities like MRI, CT scans, and X-rays, ensuring interoperability and enhancing diagnostic accuracy and efficiency.

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.
