<p>The X-ray appts. has devices to set the tube voltage, the time and/or tube current or the current/time product. The set parameters are converted into proportional electrical quantities and passed to two interconnected, interdependent control circuits one for processing the tube voltage, current and time and the other for processing the tube voltage and current/time product. The two control circuits contain a function generator that reproduces the tube's load curve. The computation takes place in analog form and the transmission to the setting elements in digital form.</p> |
