Welcome to QuantImage v2

QuantImage v2 platform

QuantImage v2 (QI2) is an open-source web-based platform for no-code clinical radiomics research. It has been developed with the aim to empower physicians to play a leading role in clinical radiomics research. We believe that tighter involvement of domain experts is critical to ensuring the clinical relevance of radiomics research and will lead to the development of better interpretable and more generalizable radiomics models.

Citing QuantImage v2

If you are using QuantImage v2 in your research, please cite the following publication:

Abler, D., Schaer, R., Oreiller, V. et al. QuantImage v2: a comprehensive and integrated physician-centered cloud platform for radiomics and machine learning research. Eur Radiol Exp 7, 16 (2023). https://doi.org/10.1186/s41747-023-00326-z

One-stop tool for clinical radiomics research

To implement this vision, and different to most other radiomics softwares, QI2 supports all steps of a typical radiomics study workflow:

allowing the user to create patient cohorts,
extracting radiomics features from regions of interest (ROIs) of CT/PET/MR images,
exploring and selecting features using visualisation, as well as
creating and evaluating machine learning models for classification and survival tasks.

Furthermore, QI2 was designed to integrate well into the clinical environment:

providing PACS-like functionality for managing imaging studies,
ubiquitous access through a web portal, and
guiding the user through the radiomics analysis processs.

Built upon established Open-Source components

QI relies on established components for medical image management, radiomics feature computation and machine learning, including Kheops, an open-source web-based for managing collections of DICOM images, pyradiomics for feature extraction and scikit-learn / scikit-survival for machine learning model development and evaluation.

Overview

The video below is an introduction to the QuantImage v2 radiomics research platform and its features:

Getting Started

You can try out the platform here. Registration gives you access to a fully functional installation of QuantImage.

Currently, we provide access to a subset of the UPENN-GBM from the Cancer Imaging Archive for testing. Please continue reading here for further information about using this collection in QuantImage.

In order to get access to testing datasets, first log into the Kheops Platform once to initialize your user account, then contact us to request the access to the datasets.

QuantImage v2 Virtual Machine

To make it easy for you to test QI2 with your data, we provide QI2 as a (VirtualBox) Virtual Machine image here.

NOTE : The download (zip archive, ~13GB) includes a README.md file with indications on login credentials, updating the platform, etc. The QuantImage v2 Virtual Machine is pre-configured to use 8GB of RAM & 4 CPUs, which corresponds to the minimum specifications for running the platform smoothly.

Setup Script (requires Docker & Git)

To easily get started and create a running instance of the full platform (Kheops, QuantImage v2 Frontend & Backend, Keycloak, OHIF Viewer, etc.), clone the following repository and run the setup script as described in the README.md file :
