Interventional Imaging Laboratory

The main objective of the Interventional Imaging Laboratory (LIVE – Laboratoire d'imagerie interventionnelle) is to study innovative solutions for navigation assistance in the medical field. We specialize in the reconstruction and automatic analysis of anatomical structures using medical images.

Areas of expertise:

  • Medical image analysis
  • Computer vision
  • Augmented reality
  • Artificial intelligence
  • Machine learning
  • Pattern recognition

Our research focuses on three main topics related to interventional imaging:

An image of the heart obtained by angiography.

We use artificial intelligence to analyze images of vascular structures.

We have proposed a number of approaches for the segmentation, monitoring, recalibration and 3D reconstruction of vascular structures to assist clinicians in their practice. Our work has led to significant breakthroughs in the analysis of X-ray images, and allows for better management of exposure to ionizing radiation during heart surgery.

We work with transesophageal echocardiography (TEE), a new ultrasound imaging modality intended to visualize intraventricular communications among patients with congenital heart disease. We have created our own heart replicas using pre-operative images and 3D-printed molds, which enables us to reproduce interventions using ultrasound guidance.

An image of the inside of a coronary artery obtained by CCTA.

We also work with optical coherence tomography (OCT) imaging, which allows us to see inside coronary arteries.

We train image recognition models to better characterize biomechanical properties of tissues (intima, media and adventicia).

CHU Sainte-Justine

CHU Sainte-Justine

Through this partnership, we have conducted advanced research work with the first hybrid room in Canada, representing an investment in excess of $6 M from the CHU Sainte-Justine Foundation.

We are currently working in collaboration with radiologists who specialize in cardiology and with cardiologists from the Pediatric Department.

Center for Virtual Imaging Trials

We are also collaborating with the Center for Virtual Imaging Trials at Duke University. We use physical simulation tools that allow for the generation and biomechanical simulation of medical images. These simulation tools, which are used in industry, are extremely important for validating our approaches, thus leading to the proposal of realistic solutions.

Granting agencies

CRSNG Fonds de recherche Nature et technologies


Our laboratory is constantly seeking dynamic and enthusiastic students to advance the knowledge base in the field of medical imaging. We recruit undergraduate, graduate and post-graduate students.

Our projects are mainly carried out in collaboration with CHU Sainte-Justine, with the goal of developing new approaches for improving the health of mothers and children.

To apply, please send your CV, transcript and a brief statement of interest to the Director of LIVE, at
