A file with a .dcm extension is opened using an associated file application, such as the GIMP software for Windows, MAC and Linux, Adobe Photoshop CS6 for Windows and MAC or ACD Systems Canvas 14. A DCM file is a digital image that is generally associated with image files saved in the DICOM format.
DICOM, which stands for Digital Imaging and Communications in Medicine, is an image format developed by the National Electrical Manufacturers Association, or NEMA. DICOM and DCM image files were created as standardized specifications for distributing and viewing medical images.These images come from the results of various medical procedures such as ultrasonic scans, Magnetic Resonance Imaging (MRI) scans, Computed Tomography, or CT, scans and X-rays. A DCM file may also contain information and other relevant medical data of patients.
By using a computer, a file with an appended .dcm extension is opened by double-clicking it. If an associated file application is already installed, the file will automatically open and the image can be viewed. The GIMP Software, Photoshop and Systems Canvas are associated applications for DCM files. If there is no associated file application found on the computer, a user may be asked to download or purchase one.
