DICOM Format and Protocol Standardization-A Core Requirement for Digital Pathology Success

Area of Science:

• Digital Pathology
• Medical Imaging Standards
• Computational Pathology

Background:

• Digital pathology faces scalability and interoperability issues due to proprietary formats.
• Current solutions rely on conversion libraries, which are unsustainable for industrial-scale use.
• The Digital Imaging and Communications in Medicine (DICOM) standard, traditionally for radiology, is evolving to support broader medical imaging applications.

Purpose of the Study:

• To evaluate the feasibility and benefits of adopting the DICOM standard for whole slide imaging (WSI) and digital pathology.
• To demonstrate how DICOM can overcome current limitations in digital pathology data management.
• To promote the reuse of existing medical imaging infrastructure for digital pathology.

Main Methods:

• Exploration of DICOM's capabilities for whole slide imaging (WSI) and virtual microscopy.
• Demonstration of DICOM's support for various imaging types (bright-field, fluorescence, Z-stacks, cytology) and encoding methods.
• Assessment of DICOM's metadata features, color consistency definitions, and dual-format capabilities (TIFF compatibility).

Main Results:

• DICOM connectathons have confirmed its feasibility for WSI and virtual microscopy.
• DICOM supports diverse pathology data, including multichannel fluorescence, Z-stacks, and tiled encoding.
• DICOM facilitates integration with enterprise-wide storage, security, and business continuity infrastructure.

Conclusions:

• Adopting DICOM for digital and computational pathology provides a unified, scalable, and interoperable solution.
• DICOM enhances data management by embedding metadata, ensuring file utility and supporting legacy formats.
• Widespread DICOM adoption is crucial for the commercially viable clinical use of digital pathology.
