Phantoms for Computer Assisted Quality Control in Diagnostic Radiology

A portable PC makes possible the reliable organisation of the procedure for quality assurance in diagnostic radiology. All specifications and operating instructions are displayed on the screen. The possibility of on-line measuring (kV and dose) is integrated. Prompt comparison with standard data is performed. In the case of significant deviations a warning message is displayed and a repeated measurement performed immediately may clear the situation. In this connection a trend analysis, which is available, may be very helpful. In the conclusive evaluation, data can be added to records and charts. A list of items which exceed the tolerance levels or warning limits is printed out.
