Micro-CT virtual coring
Orthoslices · curved rays along true radial growth · unrolled ring-width and density profiles

Virtual core — unrolled
Density sampled at uniform arc length along the curved ray, median across ±0.5 mm along the local ring tangent. The strip below is the straightened core (dense latewood dark), as handed to the Measurement lab.

Import a slice stack
PNG or JPEG axial slices of equal size, ordered by file name. Grey values are read as 8-bit and mapped linearly to density. Nothing leaves this device.
Window / level
Orthoslices
Ray quality
Place at least two points.
Rings & dating check
Needs at least 30 rings.
Send CT-derived series
The series is stored as CT-derived with the volume hash, voxel size, slice, ray control points, step, band, every boundary and per-ring density. The volume itself is not stored.
