What is dicom format

DICOM (Digital Imaging and Communications in Medicine) is the international standard for medical images and related information (ISO 12052). It defines medical image formats that can be used for data exchange with quality that meets clinical needs.

DICOM is widely used in radiotherapy, cardiovascular imaging, and radiotherapy diagnostic equipment (X-ray, CT, MRI, ultrasound, etc.), and is used in ophthalmology and dentistry, etc. It is increasingly used in other medical fields. With tens of thousands of medical imaging devices in use, DICOM is one of the most widely deployed medical information standards. Currently there are approximately tens of billions of medical images that comply with DICOM standards for clinical use.

Since the release of the first version of the DICOM standard in 1985, DICOM has brought revolutionary changes to radiology practice, with X-ray films replaced by fully digital workflows. Just as the Internet has become a new platform for information dissemination applications, DICOM has made possible advanced medical image applications that "change the face of clinical medicine." For example, in the emergency department, cardiac stress testing, breast cancer examination, DICOM serves doctors and patients and is the standard for effective work of medical imaging.

The same format is used for all purposes, including network applications and file processing. What is different from other formats is that it integrates all information in the same data. That is to say, if there is The chest X-ray image is within your patient profile. This image can never be accidentally detached from your patient profile.

DICOM files consist of a standardized and free-form header plus a series of image data. A single DICOM object only contains one image, but this image may have multiple sets of images. This is to enable Stores moving images and other complex graphics data. The image data can be compressed and used in other formats, including JPEG, JPEG Lossless, JPEG 2000, LZW and Run-length encoding (RLE).
