CHILI /Workstation Reporting multi modal digital images Product Specification
CHILI /Workstation CHILI/Workstation is a diagnostic PACS workstation with additional functions for teleradiology. CHILI/Workstation is conforming to IHE standards and can be seamlessly integrated into the clinical workflow. The system receives the images from the imaging modalities or a PACS via DICOM and saves them in a relational database system. The workstation can be operated at an existing PACS or as a client in CHILI-PACS. The graphical user interface is available in different languages including multi-lingual character sets from the DICOM header. Local date and time formats are supported. The task of teleradiology is the transmission of radiological images to a different location for interpretation and consultation. The transmitted images can be viewed simultaneously at different locations and examined cooperatively. About us CHILI GmbH, headquartered in Heidelberg, develops innovative software for image management in medical applications. The independent, founder-managed company emerged from the German Cancer Research Center (DKFZ) as a spin-off. The three founders of the company are scientists and medical computer scientists. Their solutions for PACS and teleradiology have been on the market since 1997. CHILI grows with every challenge. In the course of the last three years, the number of staff members has doubled. The young, creative, and highly motivated team from the field of medical informatics forms the basis of success for CHILI GmbH. The company s business strategy focuses on the development of innovative medical software and the cooperation with scientific institutions (e.g. DKFZ). Thus, the transfer of the latest research findings into current software, oriented towards market requirements, is ensured.
