What this research studies

This project uses low-field MRI and MRI-safe devices together with computer-driven merging of images from multiple heartbeats to improve real-time picture quality during catheter procedures. The team will collect faster repeated MRI samples during procedures and use autonomous algorithms to synthesize higher-quality images. The approach aims to help doctors see soft tissues and catheters more clearly without X-ray fluoroscopy and its radiation. Clinical testing will show whether the method makes MRI-guided catheterization practical and safer for children.

Who could benefit from this research

Good fit: Children (from infants to adolescents) who need cardiac or vascular catheterization and would benefit from reduced radiation exposure or improved soft-tissue visualization are the ideal candidates.

Not a fit: Patients who cannot have MRI (for example due to incompatible implants or severe claustrophobia) or cases requiring devices not yet MRI-safe may not benefit from this approach.

Why it matters

Potential benefit: If successful, more children could undergo catheter procedures guided by MRI instead of X-rays, reducing radiation exposure and improving visibility of anatomy.

How similar studies have performed: Some early human work showed MRI-guided cardiac interventions are possible, but improving real-time image quality with multi-beat synthesis is a newer, still-emerging technique.
