QuantBrain · AI-Native Brain Quantification Platform

Automatic ventricle segmentation and volumetrics for hydrocephalus and shunt management

Handles both CT and MRI (T1, T1c, T2, FLAIR) — the scans NPH workups, shunt follow-ups, and pediatric exams routinely use, where most tools are MRI-only. Computes Evans Index from a 3-D mask, not a hand-picked slice, and flags every output with a per-scan uncertainty score.

What it does

Segment, measure, follow

Segment the ventricles

  • Fully-automatic lateral-ventricle segmentation across CT and T1, T2, and FLAIR MRI.
  • Editable contours when the auto-segmentation needs adjustment.

Measure what matters

  • Evans Index computed from the 3-D mask, not a hand-picked slice.
  • Per-region volume in cm³ with a built-in uncertainty score on every output.

Follow patients over time

  • Side-by-side comparison viewer, including across CT and MRI timepoints.
  • Volume and Evans-Index trend — the question that drives shunt decisions.

Intended use. QuantBrain — Ventricle is intended for radiologists, neurologists, neuro-radiologists, pediatricians, and other physicians as an initial machine-learning approach for ventricle segmentation to support diagnosis and management of hydrocephalus and shunt malfunction. Outputs are reviewed by a qualified clinician.
