Convert DCM to PGM

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 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.
