BET algorithm parameters

Fields

fractional_intensity: f64

Fractional intensity threshold (0.0-1.0, smaller = larger brain)

smoothness: f64

Surface smoothness factor

gradient_threshold: f64

Gradient threshold (-1 to 1)

iterations: usize

Number of iterations

subdivisions: usize

Icosphere subdivision level

voxel_scale: f64

Factor applied to the grid’s voxel sizes before the surface is evolved (default 1.0 = the acquisition’s own geometry).

BET’s surface model is fixed in human-scale millimetres — a 7 mm / 3 mm intensity search along each vertex normal, and curvature bounded between 3.33 mm and 10 mm radii — so on a ~1 cm rodent brain those distances span the whole head and the search runs straight through the skull. Inflating the voxel sizes so the brain reaches roughly human dimensions is the standard preclinical workaround (fslchpixdim x10 before bet); a scale of 10 suits mouse data.

The mask is returned on the input index grid either way, so nothing needs scaling back. Prefer super::rs2_net where the weights can be fetched: on an in-vivo mouse GRE it follows the inner skull, where scaled BET still leaks into the skull base.
