Magnetohydrodynamic-Driven Design of Microscopic Endocapsules in MRI

PROJECT TITLE :

Magnetohydrodynamic-Driven Design of Microscopic Endocapsules in MRI

ABSTRACT:

Microscopic medical robots capable of translating in a very bloodstream or similar liquid represent a new type of therapeutic technology for surgical interventions. This study aims to characterize a new MRI compliant method of propulsion for swimming robots using the magnetohydrodynamic result (MHD). An MHD drive may be a technique of propulsion using only electromagnetic components, while not the requirement for moving mechanical parts. By utilizing MHD voltages induced within the MRI magnetic field, the chance to propel a device and provide imaging simultaneously is presented. We tend to hypothesized that a wireless MHD-driven thruster might be developed to control endocapsules among the MRI magnetic field. A model capsule was created and evaluated in a very scaled MRI-environment, and subsequently, tested for MRI-compatibility at 3 T. Dynamic performance of the endocapsule was characterised as input power was varied. In the scaled MRI atmosphere, a peak force of 0.31 mN was observed, providing evidence that an MHD-driven endocapsule is possible in an MRI surroundings. Increased forces will be obtainable with will increase in magnetic field strength and applied power.
