pyvcad_medical module

The pyvcad_medical package holds helpers for printing medical images (CT and MRI) with OpenVCAD: named color palettes, opacity curves, and Hounsfield-unit (HU) lookup tables that a pyvcad.LookupTableConverter turns into color_rgba, plus a summary printer for a loaded DICOM series. Loading the DICOM data itself is part of pyvcad (pyvcad.DICOMLoader, see Volumes).

import pyvcad as pv
import pyvcad_medical as med

loader = pv.DICOMLoader("path/to/dicom_series")
med.print_loaded_dicom_info(loader)

opacity = lambda t: med.re_range_opacity(t, med.sigmoid_opacity_base, 0.1, 0.9)
entries = med.create_linear_gradient_hu_map(
    100, 1000, palette=med.get_color_palette("rainbow"), steps=30, opacity_function=opacity
)
to_color = pv.LookupTableConverter(
    [pv.DefaultAttributes.HU], [pv.DefaultAttributes.COLOR_RGBA], entries, pv.InterpolationMode.STEP
)
