Introduction

In the field of medical imaging, the Digital Imaging and Communications in Medicine (DICOM) standard plays a crucial role in facilitating the exchange and storage of medical images and related information. To cater to the needs of developers working with DICOM files, the Grassroots DiCoM (GDCM) library was created. This C library provides a robust and efficient way to handle DICOM files, making it an essential tool for medical imaging applications. In this article, we will delve into the features and capabilities of GDCM, exploring its benefits and uses in various development environments.

What is GDCM?

GDCM is an open-source C library designed to handle DICOM files. It is a lightweight and highly optimized library that provides a wide range of features for working with DICOM data. GDCM is not a DICOM implementation, but rather a library that provides a set of tools and functions for manipulating DICOM files. This includes support for various transfer syntaxes, such as RAW, JPEG, JPEG 2000, JPEG-LS, RLE, and deflated transfer syntax.
