System and Method for Device Tracking in Magnetic Resonance Imaging Guided Inerventions - A simplified explanation of the abstract

This abstract first appeared for US patent application 18558118 titled 'System and Method for Device Tracking in Magnetic Resonance Imaging Guided Inerventions

The system described in the patent application is designed for device localization and tracking during magnetic resonance (MR) image-guided interventional procedures. It utilizes MR images of a region of interest acquired using an MRI system and a physical device localization system to localize and track a device within the subject.

• The system includes a first neural network to localize a feature of the device on the MR images.
• A second neural network generates an estimate of the physical position of the device based on the localized feature.
• The estimate of the physical position of the device is displayed for the user.

Potential Applications: - Medical procedures requiring precise device localization and tracking. - Research in the field of MR image-guided interventions. - Development of advanced medical imaging technologies.

Problems Solved: - Ensures accurate localization and tracking of devices during MR-guided procedures. - Improves the efficiency and safety of interventional medical procedures. - Enhances the overall precision of device placement within the subject.

Benefits: - Real-time monitoring of device position during procedures. - Increased accuracy in device placement. - Enhanced patient safety and outcomes.

Commercial Applications: Title: Advanced Device Localization System for MR-Guided Interventions This technology can be utilized in hospitals, clinics, and research institutions for a wide range of interventional procedures, potentially leading to improved patient care and outcomes. The market implications include increased demand for advanced medical imaging systems and technologies.

Questions about Device Localization and Tracking: 1. How does the system ensure accurate localization of the device within the subject? The system uses neural networks to localize device features on MR images and generate estimates of the physical position of the device based on this information.

2. What are the potential applications of this technology beyond medical procedures? This technology could also be used in research settings for studying MR image-guided interventions and developing new imaging techniques.

Original Abstract Submitted

In accordance with an embodiment, a system for device localization and tracking for magnetic resonance (MR) image-guided interventional procedures includes an input configured to receive a set of MR images of a region of interest of a subject acquired using a magnetic resonance imaging (MRI) system and a physical device localization system. The region of interest includes a device. The physical device localization system includes a first neural network coupled to the input and configured to localize a feature of the device on the set of MR images and a second neural network coupled to the first neural network and configured to generate an estimate of a physical position of the device based on the localized device feature. The system further includes a display coupled to the second neural network and configured to display the estimate of the physical position of the device.
