Background:

Conquest Hospital served as a development site for Picture Archiving and Communication Systems (PACS) to guide the creation of cost-effective solutions.
The initial system, established in 1992, utilized the ACR/NEMA 2.0 protocol for image management, high-speed fiber optics, and Integrated Services Digital Network for teleradiology.

Purpose of the Study:

To evaluate the benefits and drawbacks of an early PACS implementation.
To inform the specification of future low-cost PACS and digital imaging systems.
To identify challenges in data transfer, ergonomics, and system reliability.

Main Methods:

Implementation of a PACS using ACR/NEMA 2.0 protocol and a dedicated fiber optic network.
Integration with a separate Radiology Information System (RIS) for reporting functions.
Manual construction of image reporting folders and direct radiologist access to archived images.

Main Results:

Satisfactory image and data capture and archiving.
Effective reporting function of the unlinked RIS.
Identification of critical issues including data transfer, ergonomics, and single points of failure.

Conclusions:

The identified issues led to re-specification and a commercial approach for a DICOM/HTML PACS.
The PACS is now viewed as integral to a full Electronic Patient Record system.
Hospital-wide networking and high-quality hardware are now considered essential infrastructure.
