Unique benefits of Y.XST225-VF
Focal spot size can be optimized for the application and provide a
maximum in detail visibility
Minimum effective focal spot of 80 µm and 292 W power
Circular Focal spot for best image quality
More Power than any µ-focal spot tube up to 1600 W
Closed Design in a standard 225kV housing with standard H.V.-cable

Parameters and Timing – Scanning Time QualityScan
The measured times may vary due to Windows properties
The “signal” green values are based on “rule of thumb” (number of
projections = detector pixel number multiplied by square root of 2)
Investigation not yet finished, but 5 frames integration in QualityScan
seems to be a good compromise between image quality and time
06.04.2011 | 29
Parameters and Timing – Scanning Time Y.QuickScan®
The position precise Y.Quickscan® of the Y.Multiplex is very fast
The “signal” green value are based on “rule of thumb” (number of
projections = detector pixel number multiplied by square root of 2)
Acceptable CT slices (180° rotation, 180 projections) can be done with
a complete time of 18 seconds from start to “slice view ready” !!!
Note: Please never confirm scan-times and/or reconstruction times – especially with detail
visibility - in a contract without checking the application. The 18 seconds means: No center
displacement calculation, 512* 512 * 8 layer volume. Quality see image on later slide.

The workflow of manual mode
1.
Selection of operation mode: DR or CT
2.
Confirmation by joysticks: Part moves to predefined default position
for CT or DR, predefined X-ray settings are set

The workflow of manual mode
5. Scanning, reconstruction (if not skipped)
and visualization
Estimated remaining time for scan,
reconstruction and results.
Elapsed time shown in tooltip.
