Summary
A custom web-based digital image archive using hard disk drives (HDDs) proved reliable and cost-effective for medical imaging distribution. The system showed significant increases in utilization and data volume over three years.
Area of Science:
- Medical Informatics
- Radiology Informatics
- Health Information Systems
Background:
- Implementing a digital image archive is crucial for efficient medical image and report distribution.
- Integrating with existing Digital Imaging and Communications in Medicine (DICOM) infrastructure is key for workflow optimization.
- Assessing the long-term performance of such systems is essential for validating their utility.
Purpose of the Study:
- To design and implement a web-based digital image archive.
- To integrate the archive with existing DICOM infrastructure for seamless data distribution.
- To evaluate the archive's performance, reliability, and cost-effectiveness over three years.
Main Methods:
- Utilized open-source software for reliability and cost-effectiveness.
- Employed hard disk drives (HDDs) for storage due to increasing capacity and decreasing costs.
- Monitored data entry and access patterns over two 4-month periods after 1.5 and 2 years of operation.
Main Results:
- The digital image archive demonstrated high reliability, cost-effectiveness, and suitability for its intended tasks.
- System utilization increased by an average of 160% based on measured access volume.
- Stored data volume grew by 20%, largely driven by cross-section imaging data.
Conclusions:
- A practical and expandable digital image archive solution was developed within financial constraints.
- Significant increases in system utilization, active users, and data transfer volumes were observed.
- The strategy of using HDDs for image storage proved successful and effective.
