dcm The .dcm extension files are raster image format files that are universally used by the medical community for creating and storing body scans of patients. This format was developed by NEMA (National Electrical Manufacturers Association) and is primarily associated with the DICOM (Digital Imaging and Communications in Medicine) image format files.
jpeg JPEG is abbreviated as the Joint Photographics Experts Group. It is a file extension that uses irreversible compression technology which helps in reducing the data size for storing data easier and advocates the seamless handling and transmission of content. A JPEG most commonly aids in storing digital images via "lossy compression" and includes images rendered by means of digital photography. Lossy compression does not let users restore the image file to its original quality after compression, once sized down. Some loss of the data stored in the image file occurs during the compression process. In simpler terms, when an image gets compressed, there's a reduction in its quality, thereby losing some of the graphical/visual data information; data reduction generates lower file sizes.
