openmedaxis 0.0.1

Open framework for generative medical imaging research

OpenMedAxis

PyTorch Lightning for Generative Medical Imaging.

OpenMedAxis is an open-source framework designed to make generative medical imaging research reproducible, modular, and easy to experiment with. It provides clean implementations of datasets, generative models, training pipelines, and evaluation tools commonly used in medical imaging research.

The goal is to create a researcher-first framework that removes boilerplate and fragmented codebases while keeping the system low-level, flexible, and hackable.

Why OpenMedAxis?

Research in generative medical imaging often suffers from the same problems:

• Dataset preprocessing scripts are scattered across different repositories
• Training pipelines are inconsistent and difficult to reproduce
• Implementations of GANs or diffusion models vary widely
• Evaluation pipelines are rarely standardized

OpenMedAxis aims to solve this by providing a clean, unified research toolkit for the community.

Instead of every paper reinventing the same infrastructure, OpenMedAxis provides:

• standardized dataset pipelines
• reference implementations of generative models
• modular training components
• reproducible experiment structure

Example Vision

The framework aims to make research experiments simple and reproducible.

Example usage (future API):

from openmedaxis.datasets import IXI
from openmedaxis.models.diffusion import DDPM
from openmedaxis.training import Trainer


dataset = IXI(root="data/", modality="T2")
model = DDPM()

trainer = Trainer(model=model, dataset=dataset)
trainer.fit()
