This is an international format that was developed for the purpose of storing images of the body taken with medical imaging equipment. It includes magnetic resonance and computer tomography images, ultrasound images and fluoroscopy, as well as images taken with other medical imaging equipment. DCM also stores patient information in the metadata, which form part of a single file.
This format is used to store images that have been divided into Y, U, and V color components. In this case, Y corresponds to brightness, and the variables U and V correspond to color information. This format is able to store more accurate color information than the RGB color space. The YUV Color System also allows you to store video files and save a particular sequence of images.
