What’s the status inside our bones? A quick dive into our acoustical multi-path bone investigator, or in short: AMBIT

Last Friday, our colleague Finn Spitz presented the “first fruits” of our collaborative project AMBIT at VDE DGBMT “Nacht der Biosignale”. Let’s dive into the promising development results of our osteoporosis detection device using nothing but ultrasound and acoustic signal engineering.

Our bones consist of two elements, namely trabecular structures and the cortical bone. Latter are responsible for the strength and stability of the bones and are directly affected by osteoporosis. Here, the disease creates an imbalance in bone formation and breakdown, gradually increasing the bone porosity.

To detect the density of the bone, the AMBIT device in development emits quantitative ultrasound signals at a critical angle below the bone surface, which are then measured and evaluated by a receiver. Here, the speed of sound, frequency and attenuation, for example, are then evaluated for diagnostic indications.
