Convert DICOM to PPM

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 Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.
