Standards Development Organisation
DICOM is a global, non-profit standards development organisation responsible for the internationally defined standard for the digital storage, transmission, retrieval, printing, processing and display of medical images and related information. DICOM standards define the formats for medical images that can be exchanged with the data and quality necessary for clinical use.
DICOM is used in most hospitals and laboratories globally as a means to ensure that systems can produce, store, display, send, process, and use medical images and related documents across the continuum of care. DICOM is implemented in radiology, cardiology imaging, and radiotherapy devices (X-ray, CT, MRI, ultrasound, etc.), and increasingly in devices in other medical domains such as ophthalmology and dentistry.
