The CT control unit for the CT scanner is connected to the PC via a USB interface. When this is combined with the ultrasonic echoscope GS200 / GS200i and the software AScan the result is a high-performance computer tomography device and a B-scan scanner. Two step motors (linear axis, rotational axis) can be controlled via a microcontroller. Using the PC and the control unit, the travel speed is adjusted and the positioning of the slide is controlled. The motors can also be controlled directly by hand on the control unit via rotary switches for direction of travel and/or rotation (LINEAR, ROTATION) and speed of travel and/or rotation (SPEED).

With the measurement and control software AScan, the CT control unit can also be controlled from the computer, as well as the reading out and processing of measuring data of the ultrasonic device GAMPT-Scan (order no. 10121). In this way, mechanically scanned B-Scan images can be produced as well as ultrasonic tomograms. The CT algorithm has been incorporated into the AScan software as a module. The unfiltered and filtered attenuation and time of flight images, the current A-Scan image, the settings for TGC (time gain control) and the amplitude and time of flight of the currently running line scan are graphically represented. In addition to this, the respective scanner position in millimetres and the current angle of rotation in degrees are displayed. The presentation of the CT scan (attenuation and time of flight images) is updated and gradually built up after each line scan so that the creation of the tomogram can be understood in detail. The CT and B-Scan images can be exported and printed. Depending on the time and the object, the number of rotation positions, the step size and the length of the scan can be set.
