bone_scan_check: Check if surface model is fully contained within scan volume

Description

Check if surface model is fully contained within scan volume

Usage

bone_scan_check(surface_mesh, nifti, return_limits = FALSE)

Value

If any vertices lie outside the scan volume, it raises an error.

Arguments

surface_mesh

mesh object (class mesh3d) or numeric matrix/dataframe of vertex coordinates (cols: X, Y, Z)

nifti

NIfTI image object representing CT scan.

return_limits

Logical. If TRUE returns a summary of the bounding boxes of the scan and mesh
