Analysis of the vibrations generated by the human body
State of the art/Motivation
The heartbeat originates characteristic vibrations on the thorax which can be measured with a Laser-Doppler-Vibrometer (LDV)
The detection of the heartrate, heartrate variability and the pulse wave velocity etc. were already demonstrated
The detection of the PR time is also possible
Aim of the work
Comprehensive understanding of how and with what uncertainty vibration measurements on the human body can be used for medical diagnosis
Application of a single point vibrometer and a robot supported scanning-vibrometer
Comparison of the vibration signals with electrocardiographic signals
Development of algorithms for parameter recognition
Analysis of the influence of the measuring condition for the determination of the characteristic parameters
Multichannel-Vibrometer to study the vibration in several points
Analysis of 3D vibration direction with multichannel vibrometer
In addition to the heartbeat, the detection of the contraction of the atria can be identified
Detection of AV-blocks with the Laser Doppler vibrometry is possible
Recommended settings for filters and set up are obtained
The velocity vector of skin movement changes direction during a complete heartbeat: no uniform measurement direction
Determination of the uncertainty contribution of the laser beam orientation for laser Doppler vibrometer measurements on the carotid artery
Use the vibrations generated in the human body for medical diagnosis
Determination of the uncertainty contribution of laser beam orientation for laser Doppler vibrometer measurements on the chest
Investigation of the dependence of vibration on anatomical and physiological features
