Accurate Radar-Based Detection of Sleep Apnea Using Overlapping Time-Interval Averaging
Kodai Hasegawa, Shigeaki Okumura, Hirofumi Taki +5
Radar-based respiratory measurement is a promising tool for the noncontact detection of sleep apnea. Our team has reported that apnea events can be accurately detected using the st…
Noncontact Detection of Sleep Apnea Using Radar and Expectation-Maximization Algorithm
Takato Koda, Shigeaki Okumura, Hirofumi Taki +5
Sleep apnea syndrome requires early diagnosis because this syndrome can lead to a variety of health problems. If sleep apnea events can be detected in a noncontact manner using rad…
Noncontact Respiratory Measurement for Multiple People at Arbitrary Locations Using Array Radar and Respiratory-Space Clustering
Takato Koda, Takuya Sakamoto, Shigeaki Okumura +1
We developed a noncontact measurement system for monitoring the respiration of multiple people using millimeter-wave array radar. To separate the radar echoes of multiple people, c…
Two-dimensional Ultrasound Imaging Technique based on Neural Network using Acoustic Simulation
Yoshiki Nagatani, Shigeaki Okumura, Shuqiong Wu +1
The two-dimensional (2D) ultrasound imaging is widely used in several fields. In this study, the potential of two-dimensional ultrasound imaging technique based on machine learning…
