Zusammenfassung
Seit Einführung der elektronischen Datenverarbeitung in die klinische Nuklearmedizin
konnten bedeutende Fortschritte vor allem durch Entwicklung der Kamera-Funktionsszintigraphie
erzielt werden. Durch sie werden Dimensionierung und Struktur der fachspezifischen
EDV-Anlage in entscheidendem Maße bestimmt. Ausgehend von einer Definition der zu
stellenden Leistungsanforderungen wird ein Konzept für ein universell im Bereich der
klinischen Nuklearmedizin anwendbares Prozeßrechnersystem dargelegt.
Summary
Since the introduction of data processing into clinical nuclear medicine, significant
advances could be achieved above all through the development of quantitative gamma
camera scintigraphy, which is nowadays one of the most important fields of computer
application. The technological properties of an adequate computer system for nuclear
medicine use are dependent on a large scale on the necessities of gamma camera sequential
scintigraphy. If the computer capacity to carry out fast sequential scintigraphy is
available, the system can be used for all modern scintigraphic procedures as well
as for other tasks. If we look back on the experience gathered in more than ten years,
the following areas can be named in which the use of computers appears worthwile and
desirable:
1. scintigraphic diagnostics
2. functional diagnostics
3. medical record printout
4. operational management of the department, documentation and retrieval of the patients
data
5. planning of therapy
Because of the importance of quantitative sequential scintigraphy, in many nuclear
medicine departments two or more gamma camera computer systems are used. For reasons
of costs, however, it will not be justifiable to connect each gamma camera with a
separate effective data system. Therefore systems have been tested in which several
gamma cameras are connected to a host computer via microprocessor-controlled buffer
systems and by means of DMA interfaces. From practical experience, criteria were worked
out to draw up a computer concept for data processing in clinical nuclear medicine.
