Abstract
A fuzzy control system, particularly for dose rate control in an X-ray diagnostics apparatus, such a control system converting input signals into output signals. A first and a second individual module are provided, whereby respectively at least two input signals can be supplied to the first and to the second individual module for generating an output signal. Compared to a fuzzy control system that does not comprise these individual modules, the rule base becomes smaller, only input conditions that have influence on the individual module need be provided with rules, so that a simple check of the rules for completeness is assured.
Claims9
An X-ray diagnostics apparatus with a fuzzy control system for dose rate control, comprising:
- a bearing mechanism for an examination subject;
- an x-ray exposure unit;
- means for determining start values for a dose rate control from signals specifying a type of examination subject;
- and
- means for representing one of a position of said bearing mechanism in a plane and an alignment of the exposure unit.
