DCM files are image files in the so-called DICOM format. The DICOM format (Digital Imaging and Communications in Medicine) is an open standard for the exchange of information in medicine. DICOM images are lossy or lossless in TIFF or JPEG format and are embedded in the DCM file.
In addition to images from, for example, MRI, ultrasound, X-ray and CT devices, the files may also contain segmentation, patient data, findings and image registrations. Also 3D data is possible. At the same time, the DICOM standard also represents the protocol standard that is implemented in almost every medical device for imaging and image processing procedures.
In addition, DICOM forms the basis for the PACS digital image archiving system in hospitals and clinics (Picture Archiving and Communication System). Other, often used extensions for dicom files are dic and dicom. Partially the ending is omitted altogether.
Most often resolving problems with opening DCM files is very simple. Just install an appropriate program that supports such files. All of the listed programs support DCM files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of DCM files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate DCM files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Adobe Photoshop applications is not on the list, select "Browse" option in order to manually locate the directory where Adobe Photoshop has been installed.
Sometimes problems with opening DCM files may not lie with the application itself, but can arise due to other causes, such as:
