ED–HU Calibration Analysis Tool CT Commissioning

Electron Density to Hounsfield Unit table generation, variation analysis & data-transfer validation

ED–HU Calibration Table

Average HU across selected Eclipse experiments for each material. This table can be imported into your TPS.

Calibration Curve

CT number (HU) vs. density.

HU Variation — All Materials

Box plots show the spread in CT number across selected experiments for each material.

HU Variation — Individual Material

Detailed view of a single material showing each experiment's HU value.

Per-Material Statistics

Summary statistics for the currently selected experiments.

HU Change Between Systems

Shows the difference in HU when data transfers from one system to the next. Baseline scans (No iMAR, All Plugs) used for all comparisons.

Transfer Deviation Table — Abdomen

CT ROI is the reference. Columns show the HU shift at each transfer step.

Transfer Deviation Table — All Regions

MIM to Eclipse HU shift for Abdomen, Thorax, and Head protocols.

Curve Comparison

Add multiple curves from experiment selections or imported reference tables. Set one as the reference for difference analysis.

Difference vs. Reference

Set a reference curve to see HU differences at each material point.

Comparison Table

HU values and differences relative to the reference curve.
