Mineral loss measurement
TRI/3D-TMDPurpose: Measure mineral loss from surfacesCase1 Enamel demineralization experimentIn the demineralization experiment, the CT image of the enamel after demineralization was taken, and the pre-demineralization was used as the reference, The change in demineralization with acid at the demineralized site over time is measured.
1. By pre-analysis processing, adjust the posture so that the "boundary surface between
the air and the surface of the healthy part" in the image before demineralization is
perpendicular to the Z-axis.
2. Based on the image before demineralization in which the posture is adjusted, the
"boundary surface between the air and the surface of the healthy part" fits perfectly.
And align the samples each week after decalcification so that the decalcified areas
coincide areas coincide when viewed in the XY plane.
3. As a result, D1 ch before decalcification and D2 ch to D6 ch after decalcification
each week sample images have been registered.
stored in the state of
When handling 6 or more images, use the channel save/open function to input channel data.
Please change it.
