DICOM (Digital Imaging and Communications in Medicine) is the gold standard for storing and transmitting medical images. Converting video files to DICOM format is crucial for integrating video data into medical imaging workflows and ensuring compatibility across healthcare systems.
"The integration of video into the DICOM standard is crucial for enhancing the diagnostic capabilities of imaging modalities,"
states the DICOM Standards Committee in their Supplement 202: Real-Time Video documentation.
Video to DICOM conversion involves transforming standard video formats into DICOM-compliant files that can be integrated into medical imaging systems. This process requires careful consideration of video formats, frame rates, and metadata requirements.
According to the DICOM Standards Committee, "proper metadata is critical for ensuring that video data can be accurately interpreted and utilized in clinical settings."
Before diving into conversion methods, it's important to understand what video formats DICOM supports. According to Stack Overflow, DICOM supports the following video formats:
With this in mind, let's explore the various methods and tools available for video to DICOM conversion.

When choosing a method or tool for video to DICOM conversion, consider factors such as:
The DICOM Standards Committee emphasizes that
"the conversion process must address challenges such as varying video formats, frame rates, and resolutions while maintaining synchronization between video and other imaging modalities."
While not specifically designed for video conversion, these libraries provide robust DICOM manipulation capabilities that can be adapted for video conversion tasks:
pydicom: A pure Python package for working with DICOM files. It's versatile and can be extended to handle video conversion with additional video processing libraries.
pynetdicom: Implements the DICOM networking protocol, which can be useful for sending converted DICOM files.
DCMTK: A collection of libraries and applications for examining, constructing, and converting DICOM image files. It includes tools for handling DICOM files with embedded MPEG2 and MPEG4/H.264 video.
GDCM: Grassroots DICOM is an open-source implementation of the DICOM standard. It provides tools for reading and writing DICOM files, including those with video content.
LEADTOOLS offers a powerful SDK for converting video to DICOM format. Their tutorial on creating DICOM files with H264 video demonstrates how to use their DICOM Writer filter to create a dataset with H.264 video in MPEG-2 Transport format.
Key features:
Sante DICOM Editor provides a user-friendly interface for converting various video formats (AVI, WMV, MPG, MP4) to DICOM.
Key features:
MedDream SendToPACS is a DICOM converter and sender that can convert non-DICOM images, video, and signal files into DICOM format.
Key features:
While not specifically designed for video conversion, these open-source projects provide frameworks that could be extended for video to DICOM conversion:
dcm4che: A collection of open-source applications and utilities for healthcare enterprises. It's written in Java and provides a robust foundation for DICOM operations.
Orthanc: A lightweight, RESTful DICOM server that can be used as a basis for more complex DICOM workflows, including video conversion.
For developers looking to create a custom solution, the process typically involves:
This approach requires a deep understanding of both video processing and the DICOM standard but offers the most flexibility.
"The ongoing research and development efforts focus on refining video to DICOM conversion processes, with emphasis on improving efficiency and expanding the range of supported video formats," notes the DICOM Standards Committee documentation.
