Convert DICOM to PGM

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 Portable Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.
