CHILI

Description

CHILI is a general-purpose medical image review workstation with teleradiology and telecardiology functions.

The objective of Teleradiology / Telecardiology is the transmission of radiological images or image sequences between different sites for the purpose of interpretation and consultation. Digitally transmitted images can be presented, analysed and discussed simultaneously at different sites.

Our role

The HCI division has been involved in the medical field for a long time. Over the years, our main focus has been administrative systems for the Ward Information System. We have also been part of more clinical systems development.

In this project our role has been to produce a Conceptual Design as well as a concrete User Interface Design for a teleradiology system.

More information about this teleradiology system may be found at the Division Medical and Biological Informatics at the Deutsches Krebsforschungszentrum (German Cancer Research Center).

Facts

The objective of Teleradiology is the transmission of radiological images between different sites for the purpose of interpretation and consultation. Digitally transmitted images can be presented, analysed and discussed simultaneously at different sites.

CHILI is produced by the Steinbeis-Transferzentrum Medizinische Informatik (TZMI) in Heidelberg, a transfer center for new technologies in medical informatics. The basis of CHILI is a general purpose Radiology Workstation with additional functions for Teleradiology.

CHILI is a portable, easy to handle teleradiology system, which is based on standards for communication and exchange of medical image data. CHILI conforms to the requirements of the American College of Radiology concerning teleradiology systems. Furthermore, CHILI is a modular, general purpose Radiology Workstation, which can be extended by new functions, even by those developed by the user himself.

The introduction of CHILI will reduce current costs. We have found savings in film material, the transportation of patients, staff, as well as from the sharing of resources. We know from experience that these clearly savings outweigh the resulting costs of the ISDN lines. With rapid information flow a further reduction of costs is possible, e.g. shorter hospitalization times of patients.
