Summary
Objectives:
Along with the revolution of information technology and the increasing use of computers
worldwide, software providers recognize the emerging need for internationalized, or
global, software applications. The importance of internationalization comes from its
benefits such as addressing a broader audience, making the software applications more
accessible, easier to use, more flexible to support and providing users with more
consistent information. In addition, some governmental agencies, e.g., in Spain, accept
only fully localized software. Although the healthcare communication standards, namely,
Digital Imaging and Communication in Medicine (DICOM) and Health Level Seven (HL7)
support wide areas of internationalization, most of the implementers are still protective
about supporting the complex languages. This paper describes a generic internationalization
approach for Picture Archiving and Communication System (PACS) workstations.
Methods:
The Unicode standard is used to internationalize the application user interface.
An encoding converter was developed to encode and decode the data between the rendering
module (in Unicode encoding) and the DICOM data (in ISO 8859 encoding). An integration
gateway was required to integrate the inter-nationalized PACS components with the
different PACS installations. To introduce a pragmatic example, the described approach
was applied to the CHILI PACS workstation.
Results:
The approach has enabled the application to handle the different internationalization
aspects transparently, such as supporting complex languages, switching between different
languages at runtime, and supporting multilingual clinical reports.
Conclusions:
In the healthcare enterprises, internationalized applications play an essential role
in supporting a seamless flow of information between the heterogeneous multivendor
information systems.
