Abstract

Currently available PACS networks rely on Ethernet and TCP/IP or a related standard for image transfer. We have implemented a hardware interface which is fully compliant with the ACR-NEMA 2.0 protocol, both hardware and software. The signalling bandwidth of the ACR-NEMA parallel interface is considerably higher than for Ethernet over coaxial cable. The relative performance of these two standards for a point to point link is of great interest in determining the feasibility of using the ACR-NEMA 2.0 standard for device interfacing to a larger PACS network. To compare the performance we have put together two systems, each of which supports both TCP/IP over Ethernet and ACR-NEMA 2.0. The first system is based on a PC/AT platform using the ISA bus. The second is a UNIX system based on a VMEbus platform. Each of these systems has a commercially available Ethernet interface running a commercially available TCP/IP implementation. Each system also has a DeJarnette Research Systems ACR-NEMA 2.0 interface (ANSIF). In addition, the ISA bus system also supports the Siemens PACSNet standard. Performance measurements were made for both Ethernet protocols and ACR-NEMA 2.0 between similar platforms and dissimilar platforms. Comparison of these throughput results will allow direct comparison of the competitiveness of the ACR-NEMA 2.0 standard with Ethernet. Results of the performance measurements are discussed in detail. The implications of these relative performance measurements for the future of the ACR-NEMA standard will be examined as well.
