Overview
The Harvard Catalyst Medical Imaging Informatics Bench to Bedside (mi2b2) Initiative is preparing to provide services for setting up imaging data management systems (IDMS) to support research and clinical efforts involving imaging for Harvard Catalyst affiliated investigators. Two simultaneous (and potentially conflicting) priorities are to 1) provide optimal, customized hardware and software tools for each investigator/ laboratory and 2) to harmonized these solutions to allow for aggregation of the raw and derived medical imaging data for subsequent sharing beyond the investigator/ laboratory.
XNAT has been identified as a potential software solution for providing the core functionalities of a Harvard Catalyst IDMS.
A typical IDMS service will include the following steps:
- Requirement gathering
- Gap analysis
- Infrastructure setup
- Data modeling
- IDMS installation and setup
- Data loading
- Testing and evaluation
- Ongoing data entry, data loading/transfer, and system monitoring and maintenance
- System upgrade
mi2b2 Phases
Planning and Information Gathering
The goals of current phase of the initiative are to:
- Gather concrete and specific requirements for imaging data transfer and management from a number of high-volume imaging projects led by Harvard Catalyst-affiliated investigators that are generating valuable derived image data with the intention to share that data beyond their own laboratory;
- Generate a list of overlapping requirements from these specific investigators;
- Prioritize the projects to determine next steps;
- Deploy a demo IDMS based on the default XNAT source code;
- Assess the effort required to extend XNAT code to support the features identified.

- Stephan Voss, CHB
- Simon Warfield, CHB
- Bill Hanlon, DF/HCC
- COPD Gene Project, BWH
- Brad Dickerson
Project Prioritization Criteria
Possible criteria include:
- Impact
- Number of users
- Duration of the project
- Amount of data (# of subjects, # of scans ...)
- Success Potential
- Commitment of PI
- Feasibility: is it a good fit for using XNAT?
- Availability of project support at each stage of the effort, including requirement gathering, data collection, system testing, continuing IT and informatics support.
Current Status
Test installations of XNAT (1.4 release candidate 2) were done on Windows XP and Linux in VMware. Minor issues in the setup process needs to be fixed to make successful installation on Windows Vista.
Requirement gathering from several research and clinical projects have been conducted.
Other Software
In addition, an evaluation of dcm4chee|[1] (a DICOM Implementation in JAVA) is in progress. Simon's group runs an instance of dcm4chee. XNAT's DicomServer and DicomBrowser are based on dcm4che.
The Globus MEDICUS (Medical Imaging and Computing for Unified Information Sharing)|[2] has been proposed to provide an image sharing solution.
