Automatic functions and system reports
Geminy aims to free users from routine work by automated functions
for calibration and system performance tests:
• Geometric calibration checks and corrects component orientations and
positions.
• Detector calibrations offer automatic single-gain, multi-gain, and
step wedge calibration. Expert mode with additional options for further
optimization.
• ASTM report is created in accordance to ASTM E1695 for MTF and CDF.
• MPE
SD
: fully automated determination and documentation of maximum
SD deviation referring to VDI/VDE 2630 – Sheet 1.3. Measurements of the
sphere distances of the Yxlon ruby gauge at two positions.
• Separation breaks multiple parts into individual volumes.
Reconstruction workspace and reconstruction improvements
CT systems based on Yxlon Geminy are equipped with separate workstations
for controlling the system and for reconstruction and analysis. The reconstruc-
tion workspace manages reconstructions and calls CERA-algorithms including:
• Jitter correction to eliminate any blurry edges caused by a focus drift or
shifted parts
• Truncation correction to correct truncation artifacts on ROI scans where the
inspected part fills the entire field of view
• Ring artifact correction for processing projections or volume or detector shift
corrections
• Beam hardening correction/reduction: Various methods are available for
reducing these artifacts, including model-based corrections.
• Metal artifact reduction: FSMAR helps in surface extraction, especially with
plastic-metal mixes and metrological applications.

2D image optimization
As a software platform, Geminy is also used for radioscopy inspection.
Numerous image enhancement options, such as HDR, eHDR or adaptive
sharpness filters are implemented.
