mrilite

mrilite is a lightweight Python toolkit for handling 3D MRI volumes.
It provides simple and minimal utilities for:

• loading and saving NIfTI files
• basic preprocessing (z-score normalization)
• visualizing MRI slices
• overlaying segmentation masks

Designed to be small, dependency-light, and easy to reuse across many MRI projects.

Installation

Using pip:

pip install mrilite

Or install locally:

pip install -e .

Quick Start

from mrilite import load_nifti, zscore, show_slice_with_overlay

vol = load_nifti("t1.nii.gz")
seg = load_nifti("seg.nii.gz")

vol = zscore(vol)

show_slice_with_overlay(vol, seg, axis=2, index=80)

Features

• Minimal and clean API
• Works with any 3D/4D NIfTI MRI
• Transparent segmentation overlay
• Only essential dependencies (numpy, nibabel, matplotlib)
