The digitization of radiology affects all areas and departments of service providers in health care and clarifies the changed requirements to historically grown structures, as well as to the dynamic service processes. An implementation of information systems by service providers is a complex task, the complexity of which is increased with integration in teleradiology networks. The relevant influence factors of the digitization of the radiology on patients, processes and economics were examined by theoretical analysis observations and the results were integrated into the implementation method. The developed method for the implementation of information systems in complex overall systems is arranged in a holistic and patient-oriented manner. Information containers form the core of the implementation method. Within the modular information containers all information relating to one process is set in relationship with each other in a matrix on several levels. From the information containers the individual projects are generated. The implementation method is an instrument of the strategic management, since the technical conception and conversion of information systems require a previous adjustment of structures and processes.

Research Objectives and Themes
This thesis aims to explore the multifaceted impact of the digitization of radiology on healthcare, specifically analyzing its influence on patients, clinical processes, and economic structures. The primary research objective is to develop a holistic, patient-oriented implementation method for information systems within teleradiology networks, addressing the complexities inherent in modern healthcare integration.
- Theoretical analysis of the impact of digitization on patients, processes, and the economy.
- Development of a comprehensive, modular implementation method using "information containers."
- Standardization and integration of heterogeneous healthcare IT systems (PACS, RIS, HIS).
- Emphasis on patient-centered care and process optimization as strategic management tools.
- Managing complexity in interdisciplinary teleradiology network environments.
Excerpt from the Book
2.4 IMAGE COMPRESSION
The storage and distribution of images is a central task of PACS systems. Depending on the investigations and recording type the quality requirements vary with the images produced. For example, in ultrasound images of a resolution of 320 x 240 or 640 x 480 pixels at a gray value resolution of 8 bits per pixel are sufficient. Other the hand, in digital X-ray images a resolution of 2048 x 2048 pixels are required and a gray value resolution of 10 bits per pixel. The size of medical images grows progressively with increasing image and gray value resolution of imaging devices. The total data volume of radiology in the average hospital is therefore very large and makes heavy demands on storage capacity, performance and data transfer. The effective storage and fast transmission of medical images between the transmitter and receiver with direct phone lines, local or global networks like the Internet are important strategic issues of digital radiology.
High data rates are usually only available in local area networks (LAN - Local Area Network), whereas the communication outside the immediate proximity is only possible through networks with limited capacity such as ISDN, GSM or the Internet. To meet these demands, the picture data must be compressed.
