Measurement of instantaneous orthostatic heart rate change has been used as a screening method for care or rehabilitation for the elderly, because it allows evaluation of the auton...

Aortic wall changes dimensions and mechanical properties in response to mechanical stimulation. As these changes are driven by the cells inside the wall, and their mechanical respo...

Some systems to measure voided volume and flow rate have been developed. Clinically, urination parameters are measured using uroflowmeters that have special receivers such as cups ...

Because radiofrequency (RF) coils used in magnetic resonance imaging (MRI) are specific for given regions of interest in the human head (HH), it is necessary to adjust the capacita...

In this paper, we propose an algorithm to construct a spatiotemporal statistical shape model (SSM) of the brain surface of a human embryo. Our model is based on level sets and the ...

An extracorporeal membrane oxygenator (ECMO) is used for the management of severe heart or respiratory failure. In the conventional ECMO system, centrifugal blood pumps are commonl...

We have proposed and developed a vibratory microinjection system (VMS) to facilitate gene transfer and to increase the efficiency in production of transgenic animals. The VMS injec...

We examined muscle stiffness at various pedaling rates under conditions of constant power output. Eight healthy young participants pedaled a cycle ergometer at a power output of 47...

AI-based medical and healthcare devices and systems have unique characteristics including 1) plasticity causing changes in system performance through learning, and need of creating...

Surface electromyographic (EMG) signals are known to be strongly influenced by anatomical, physiological and detection system parameters. Among the detection system parameters, we ...

After experiencing natural disasters, accidents, and shocking incidents, some children experience post-traumatic stress disorder (PTSD). A respiration control method that relaxes t...

Wearable thermometers are popular devices for measuring body temperature during fever, as well as for monitoring basal temperature in women. They are easy to handle, inexpensive, a...

Extracellular volume fraction mapping (ECV Map) can provide quantitative measurements of myocardial tissue with amyloid deposition and myocardial edema. ECV measurements have been ...

In this work, we developed a measurement system that uses LEDs to estimate multiple components such as urea and creatinine in spot urine samples using near-infrared spectroscopy, c...

Evaluation of the impeller radial stability is important from the bioengineering point of view in the development of mechanical circulatory support devices (MCSDs) for safer use as...

Gait characteristics vary among people and correspond to individual differences of external and internal traits. Recent studies on autism spectrum disorders (ASD) reported that gai...

Simultaneous measurements of mechanomyogram (MMG) and electromyogram (EMG) may be useful for accurate evaluation of skeletal muscle contraction. However, unlike the EMG, the MMG is...

As the pathological characteristics of living tissue generally correlate with tissue stiffness, techniques such as ultrasound elastography play an important role in the medical fie...

Electrocardiograms (ECGs) captured by wearable ECG devices readily contain artifacts due to measurement faults. Since artifacts and R waves have quite similar frequency characteris...

The liver plays a central role in all metabolic processes in our body. Currently, orthotropic liver transplantation is the only proven effective treatment for serious acute liver f...
