Alternating direction method of multipliers applied to medical image restoration
Kenya Murase
We investigate the effects of the regularization parameter for the norm () and penalty parameter () in the alternating direction method of multipliers (ADMM) on the quality of rest…
Generation of System Function Maps in Projection-Based Magnetic Particle Imaging Using Lock-in-Amplifier Model
Kenya Murase
We previously developed a system for projection-based magnetic particle imaging (MPI) with a field-free-line (FFL) encoding scheme. In the projection-based MPI, projection data are…
Behavior of Signal Harmonics in Magnetic Particle Imaging Based on a Lock-in-Amplifier Model
Kenya Murase
We previously presented a lock-in-amplifier model for analyzing the behavior of signal harmonics in magnetic particle imaging (MPI). In that study, the magnetization and particle s…
A simulation study on image reconstruction in magnetic particle imaging with field-free-line encoding
Kenya Murase
The purpose of this study was to present image reconstruction methods for magnetic particle imaging (MPI) with a field-free-line (FFL) encoding scheme and to propose the use of the…
Heat Transfer Simulation for Optimization and Treatment Planning of Magnetic Hyperthermia Using Magnetic Particle Imaging
Natsuo Banura, Atsushi Mimura, Kohei Nishimoto +1
This study was undertaken to develop a system for heat transfer simulation for optimization and treatment planning of magnetic hyperthermia treatment (MHT) using magnetic particle…
Development of a computer-aided diagnostic system for Alzheimer's disease using magnetic resonance imaging
Kenya Murase, Naohiko Gondo, Tsutomu Soma
Alzheimer's disease (AD) is the most common type of dementia accompanied with brain atrophy. Structural measurements of brain atrophy in specific brain structures such as hippocamp…
