DCM images: Frequently Asked Questions
What are DCM files?
DICOM (Digital Imaging and Communications in Medicine) is a standard used for storing, transmitting, and managing medical images and related metadata. Files commonly use the .DCM extension.
DICOM is widely used in healthcare to exchange medical imaging data between imaging devices, systems, and healthcare providers. A DICOM file can contain medical images such as X-rays, CT scans, MRI scans, and ultrasound images, along with associated information like patient demographics, study details, and imaging parameters.
The DICOM standard ensures interoperability between different medical imaging systems and enables consistent handling of medical imaging data across healthcare environments.
DICOM files can store single-frame images or multiframe images. Multiframe DICOM files contain multiple image frames within a single file and are commonly used for CT, MRI, ultrasound, and other multi-slice or time-based studies.
Multiframe DICOM files can be:
- Classic (simple) multiframe, using a traditional frame structure
- Enhanced multiframe, which follows newer DICOM standards and provides improved metadata organization and support for complex imaging modalities
reaConverter supports DICOM files conversion, including Enhanced multiframe DICOM (DCM), allowing proper processing of modern multiframe medical imaging data.
