This is a doppler audio signal, ...
its frequency spectrum, ...
doppler spectrum derived uro-flow curve in high resolution, ...
and a more traditional smoothed view. In conventional urodynamics measurement...
a patient must go to a device like this and exactly target the measuring cup.
Almost of diagnosis can be made with how and how and so on.
In 1988 we did it by stand-alone 24GHz millimeter wave Doppler.
Using a wearable sensor, now, we do the same with 40kHz airborne...
ultrasound Doppler.
Do it yourself
As said before, we derive uro-flow curve from Doppler spectrum, ...
typically by its ridge trace.
Opposed to traditional methods, we skip quantity-time measurement, ...
and go directly to flow pattern observation by Doppler.
Imagine you can compare with other peers, or check how healthy you are this morning
Measurement of *** must be in a usual environment.
Any unusual situation changes it to unusual.
Hospital mounted device will never be ideal in this sense.
Do it for yourself in your living environment Is the best way.
Our doppler device is finger mountable like this.
These are our latest prototypes, ...
and these are our single transducer model ...
and dual transducer model.
During preclinical laboratory tests over 87% successfully acquired this style of ...
diagnostic quality urination pattern data.
Yet, all failures were caused by wrong positioning or direction of transducer.
The product hasn't yet been produced since we are a national university.
The ABUS Urodynamics research group in Asahikawa Medical University, ...
