We are a urodynamic study instrumentation group in the urologic surgery department of Asahikawa Medical University, Hokkaido, Japan. Our story begins with our long-haul R&D in realtime, remote contact-less measurement of intra-bladder pressure with our own tiny wireless capsule telemetry device. With our capsule telemeter we have captured a fantastic simultaneous recording of on-site pressure trend and intra-corporeal phonocardiographic signals of a small animal, and its heart rate also. The project is progressing toward human use. However, for urology another aspect is even more important: urination behavior, or urodynamics study. For that we are leveraging our proven sensing technology: non-contact, Doppler measurement of running urea (uroflowmetry). Unlike our first device from 20 years ago, we now use airborne ultrasound rather than mm-wave electromagnetics for cost and simplicity and, most importantly, minimal operating power demand.
Our latest wearable (patient finger-mounted) pre-clinical device based on 40 kHz airborne ultrasound CW-Doppler, submitted here for competition, will revolutionize urological clinical diagnosis as well as patient-managed health checks, with the patient’s own PDA or trans-network diagnosis. We are concentrating on our proprietary detection and signal processing technology, which will work with today’s available signal or data transmission and archiving technology. We believe our sensing technology and system concept are outstanding, and will make for viable entries in this competition.
About Team Leader
Yasuhito received an M.S. (1969) and a Ph.D. (1995) in electronic engineering from Tohoku University, served as R&D engineer in Aloka ('69-'73), Yokogawa-Hewlett-Packard ('73-'79), Yokogawa Electric Works ('79-'83), and in GE-Yokogawa Medical Systems ('83-'98) as R&D manager for medical ultrasound engineering. After serving as a guest researcher at University of Michigan (1998), he was Professor in Information and Computer Science in Kagoshima University (1999-2010), and is now retired.
He is a senior member of IEEE, regular member of IEICE, IEEJ, JSMBE, JSUM, ASJ, JSOG (Japan Society of Obstetrics and Gynecology) and life member of ISOB (International Society of Biotelemetry). His research interest has been based on, but not limited to, medical electronics, medical ultrasound, monitoring, and remote sensing with biotelemetry.
