Project Title: Acoustic polymer lenses for 2D microfabricated ultrasound transducers
Group:  MEMS Applied sensors
Supervisors: Erik Vilain Thomasen, Jorgen Arends Jensen and Kristoffer Almdal

Project Description: 
The primary objective of this project is to develop integrated acoustic polymer lenses for 2D microfabricated ultrasound transducers to increase their field of view. These row-column addressed (RCA) ultrasound transducers are only forward looking, i.e. they can only make an image of structures directly below the surface of the transducer. Lensed RC arrays have recently been introduced to increase the field of view. In this work, we will investigate compound lenses for RCA ultrasound transducers and optimize their refraction and attenuation properties. 

Perspective:
This narrow field of view is a severe limitation for widespread use of such transducers, in particular for abdominal or cardiac imaging, where a curvilinear volume region is a necessity. 
Overcoming this limitation will enable doctors to perform 3D ultrasound imaging in real time at the capillary level. Thus, these new lensed CMUT probe combined with super resolution imaging technique could open for new possibilities in treatment and diagnosis.
