What is DICOM? The Complete Guide to Medical Imaging Standards

Written by Pär Kragsterman | October 23, 2024

DICOM (Digital Imaging and Communications in Medicine) is the international standard for medical images and related information. It defines the formats and protocols for storing, transmitting, and managing medical imaging data, enabling healthcare providers to seamlessly share and access diagnostic images across different systems and devices.

The Evolution of Medical Imaging Standards

The journey of medical imaging has come a long way since the traditional film-based X-rays. According to the DICOM Standard organization, since its inception in 1993, DICOM has revolutionized healthcare by facilitating the transition from physical films to fully digital workflows. Today, it stands as one of the most widely deployed healthcare messaging standards globally.

"DICOM® is utilized by virtually every medical profession that uses images in the care of patients – from cardiology to dentistry to ophthalmology," states the DICOM Standard website.
