Improvement in magnetic nanoparticle tomography estimation accuracy by combining sLORETA and non-negative least squares methods

Teruyoshi Sasayama et al.

Summary: This study proposes a method that combines magnetic nanoparticle tomography (MNT) and standardized low-resolution brain electromagnetic tomography (sLORETA) to accurately estimate the concentration and position of biofunctionalized magnetic nanoparticles (MNPs) and successfully suppress artifacts caused by measurement noise.

Long-range stray field mapping of statically magnetized nanoparticles using magnetoresistive sensor

Suko Bagus Trisnanto et al.

Summary: Analyzing the spatial distribution of stray field from magnetic nanoparticles is crucial for designing and optimizing magnetometric systems in clinical magnetic particle imaging scanners. In this study, a magnetoresistive sensor was used to directly measure the stray field from a commercial magnetic nanoparticle suspension under a static field. The results show that the spatial distribution of the stray field is correlated with the geometry of the sample.

Magnetic particle imaging using linear magnetization response-driven harmonic signal of magnetoresistive sensor

Suko Bagus Trisnanto et al.

Summary: This study achieved a harmonic-rich signal by utilizing linear magnetization responses of magnetic nanoparticles, providing a new approach for magnetic particle imaging. By using a magnetoresistive sensor, the research team proposed a strategy to exploit the linear responses of tracers, resulting in high-contrast images of a solid ferucarbotran phantom and bringing new expectations for clinical use of MPI.
