Holder for ultrasound Transducers

The ERC BioMechTools project aims to "develop diagnostic and evaluation tools to quantify the degenerative status of orthopaedic patients". Within the University of Twente we try to do this by making a device that tracks the bone positions within the leg in 3D using ultrasound.
Proof of concept
A first proof of concept has been made where we place small ultrasound transducers on the skin of the leg. We hope to get a good ultrasound signal from the bone, but in practice the strength of the signal is very dependent on the bone geometry and the location and orientation of the transducer.
As you can see in the image above, it is possible to make a personalized splint or cast for a limb. In our research we know the bone geometry of our patients and we know the properties of the ultrasound signal. Your assignment will be to create a personalized "holder" for our ultrasound transducers, which will help us to get the best signals available for our measurements.
Your assignment will start with literature research about available devices and ultrasound characteristics. After that, you will have to implement an algorithm to find the best transducer locations and orientations. The icing on your cake will be to 3D print your holder, and test it on one of our subjects.
