We simulated the three-dimensional contraction of the lateral rectus muscle using the finite element method. We proposed a hyperelastic, transversely isotropic constitutive model f...

Minimally invasive therapies by applying cavitation bubbles, such as histotripsy and gene transfer, have recently attracted attention. As a method to generate bubbles, the use of e...

This paper reviews endeavors over the past decades to achieve seamless monitoring of various types of physiological information by a variety of high user-affinity approaches applic...

Pituitary tumors frequently compress the optic chiasm, causing visual field deficits. Surgical removal of these tumors could improve visual functions. Thus, predicting the prognosi...

Control of vasospasm is one of the most important problems in postoperative management after the occurrence of subarachnoid hemorrhage. Transcranial Doppler ultrasonography (TCD) i...

Mitochondria are subcellular organelles that synthesize ATP, generate reactive oxygen species (ROS), and control cellular fates such as apoptosis and aging. Mitochondria generate d...

In this study, we proposed and examined the evaluation method for image processing of capillary vessels in the fingertips. Objectification of an image has many problems; especially...

Many different quadrupedal walking patterns (gaits), such as “walking”, “trotting”, “bounding” and “galloping” can be generated by systems of coupled central pattern generators (CP...

Recently, ultra-low field MRI (ULF-MRI) has attracted attention as a medical imaging technique. In ULF-MRI, because nuclear magnetization is very weak, hyperpolarized nuclear magne...

The aim of this study was to identify factors affecting the relationship between heart rate variability (HRV) and physical acceleration (PA) in daily lives of free-moving adults. I...

We previously proposed the use of acoustic microbubble delivery in blood vessels as a therapeutic application of microbubbles to improve the efficiency of high-intensity focused ul...

Gaze information has been used in numerous fields such as cognitive psychology research, input interfaces, and intelligent transport systems. In this study, we focused on electro-o...

The purpose of this study is to develop a simple back assistive device that generates sufficient assistive moment and is not subject to resistant forces while walking. It is widely...

We determined the anatomical geometry and thicknesses distribution of the triceps surae aponeuroses from anatomical observation of a human cadaver. Geometry of the aponeuroses was ...

Atonia during rapid eye movement (REM) sleep is absent in patients with REM sleep behavior disorder (RBD), a phenomenon called REM sleep without atonia (RWA). RBD patients have sym...

The maximum cross-correlation coefficient (ρmax) between blood pressure (BP) and heart rate (HR) variability for frequency components limited to the Mayer wave-related band is usef...

MRI-guided surgical ablation has been used as a novel technique to achieve minimally invasive glioma resection. In this surgery, low-power thermal energy is supplied via a laser pr...

In this paper, we describe a robotic ultrasound (US) probe scanning system for reducing the manual tasks of US technicians and assisting in interventional procedures. The system co...

Traditional Chinese medicine considers the nutritive Qi?which is transported and regulated by the meridian system?to be the major source of energy for the human body. Modern medici...
