Multi-modality Platform for Specific Imaging in Cardiology

MUSIC (Multi-modality Platform for Specific Imaging in Cardiology) is a software developed by the ‘Multimodal Data Science’ team of the IHU Liryc and the Inria Epione and Inria Carmen teams. The objective is to offer a large range of functionalities and processing chains dedicated to cardiology, both for diagnosis and for therapeutic guidance. MUSIC is made of several modules, such as the MUSICardio software, based on the medInria open source software. It offers :

About the MUSICardio tool

Segmentation, visualisation, filters, histogram, reformatting, registration and mesh management tools are proposed and allow the community to use an ergonomic and more efficient software system. Many imaging modalities are supported: MDCT, MRI, PET, VTK meshes, etc. In addition, the generated models are exportable to electro-anatomical 3D mapping systems used by cardiologists during interventions on cardiac rhythm disorders (catheter ablation).

MUSICardio offers image processing algorithms for diagnostic or prognostic purposes, processing chains intended to guide interventions on atrial and ventricular arrhythmias through imaging. Thus, MUSICardio has been used to guide ventricular tachycardia (VT) ablations in more than 300 procedures in our centre, and more than 1500 in the international MUSIC network.

MUSICardio is a software platform that allows multi-parametric data from the various IHU teams (structural, mechanical, haemodynamic, electrical, etc.) to be analysed in the same environment, and to interface with simulation software platforms such as SOFA, CEPS and CARP in order to develop modelling/simulation strategies tailored to the patient.

An international consortium of centres specialising in TV was created within the framework of the MUSIC project. It now includes more than 30 international centres. Participating centres send their anonymised data to our team through a web portal. Our radio handlers process them within hours and send them back to the partner centre in time for the intervention. Every day, cardiologists from all over the world use this technology to guide their interventions and visualise their catheters in real time within a personalised virtual heart produced in Bordeaux. In addition, this multicentre network allows the creation of an international registry of structural cardiac pathologies including imaging and electrophysiology data.
