Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Area of Science:

Robotics
Biomedical Engineering
Gastroenterology

Background:

The gastrointestinal (GI) tract's confined space limits ingestible device size.
Existing mesoscale magnetic crawlers struggle with integrating functional components like electronics.
Surgical-free diagnostic and treatment strategies require advanced ingestible systems.

Purpose of the Study:

To develop an ingestible magnetic robot with a centralized compartment for functional integration.
To demonstrate the localized flexibility (MR-LF) enabling modular component attachment.
To overcome the size limitations of ingestible systems for enhanced clinical applications.

Main Methods:

Designing a magnetic robot with a localized flexible compartment (MR-LF).
Integrating modular functional components, including commercial electronics and drug payloads.
Testing the MR-LF's ability to perform drug delivery and guide continuum devices.

Main Results:

The MR-LF successfully integrated electronics and drug delivery capabilities within an ingestible form factor.
The system demonstrated bidirectional locomotion in confined lumens and air-water environments.
The localized flexibility allowed for the incorporation of modular payloads without compromising functionality.

Conclusions:

The MR-LF enables the creation of highly-integrated ingestible systems for surgical-free interventions.
This technology addresses the challenge of integrating electronics and payloads in confined GI environments.
The developed system has the potential to meet significant unmet clinical needs in diagnostics and therapeutics.
