Magnetic particle imaging in vascular medicine

Innovative Surgical Sciences, 2018
Magnetic particle imaging (MPI) is a new medical imaging technique that enables three-dimensional real-time imaging of a magnetic tracer material. Although it is not yet in clinical use, it is highly promising, especially for vascular and interventional ...

Magnetic-Particle-Imaging [PDF]

, 2012
Magnetic-Particle-Imaging (MPI) ist ein neues tomographisches Verfahren fur die medizinische Diagnostik. Es wurde erstmals 2005 in der Zeitschrift Nature von B. Gleich und J. Weizenecker vorgestellt [125]. In MPI wird keine naturliche Konstante des Gewebes gemessen, sondern die ortliche Verteilung eines speziell verabreichten Tracers.

Superferromagnetic Disk Particles for Magnetic Particle Imaging. [PDF]

Small Methods
Abstract Magnetic particle imaging (MPI) offers rapid, highly sensitive tracer‐based imaging without ionizing radiation, but its clinical translation remains challenged by the limited performance of existing superparamagnetic (SP) tracers. In this work, precisely engineered disk‐shaped nanoparticles fabricated from superferromagnetic (

Simulation Research on the Forward Problem of Magneto-Acoustic Concentration Tomography of Magnetic Nanoparticles With Magnetic Induction Based on the Relaxation Time of Magnetic Nanoparticles

IEEE Access, 2022
Magneto-acoustic concentration tomography of magnetic nanoparticles (MNPs) with magnetic induction (MACT-MI) is an emerging method for magnetic particle imaging based on the magneto-acoustic coupling effect. However, the limitation of this method is that

Fluid-Induced Propulsion of Rigid Particles in Wormlike Micellar Solutions [PDF]

, 2014
In the absence of inertia, a reciprocal swimmer achieves no net motion in a viscous Newtonian fluid. Here, we investigate the ability of a reciprocally actuated particle to translate through a complex fluid that possesses a network using tracking methods
