TitleHealth Monitoring for the Heart and Aorta
OwnerGeorgia Intitute of Technology

Ballistocardiography (BCG) is a non-invasive measurement of the reaction of the whole body generated by the ejection of blood at each cardiac cycle.  Consequently, it is an integration of multiple forces related to movements of blood inside the heart, inside the arteries (primarily the aorta), and the heart itself.  However, its application has been restricted by a limited understanding of the physiological interpretation of the BCG signal and its deformations. Thanks to the development of novel technologies and signal processing methods for measurement and analysis, BCG is enjoying a resurgence as a potential clinical tool.

Technology: Inventorsat Georgia Tech have developed a mathematical model that relates BCG to systemic arterial blood pressure and flow.  The expression for the cardiac force acting on the body was derived in terms of systemic arterial blood pressure and flow via Reynolds Transport Theorem and Newton’s 3rd Law.  Proof of concept studies show that the pressure gradient in the systemic arteries is the primary mechanism responsible for the genesis of force BCG.  The model enhances the fundamental understanding of BCG and enables its use as a non-invasive and low-cost screening tool for vascular disease.

Potential Commercial Applications:

  • Medical and healthcare devices 
  • Equipment that screen and assess diseases in the heart and the arteries
  • Iintegrated as feature of embedded medical devices for wearable activity trackers

Benefits / Advantages:



  • Enhances fundamental understanding of BCG, including the physical mechanism of its genesis and the implication of its key waves
  • Makes it possible to interpret the BCG to deduce the integrity of the cardiac functions
  • Enables the use of BCT as a non-invasive and low-cost screening tool for vascular disease
