Amir Rosenthal, PhD, Associate Professor

The Rosenthal laboratory for biomedical imaging and sensing (LBIS), at Technion’s Faculty of Electrical Engineering, is dedicated to the development of new technologies for medical and biological applications. Research at LBIS is focused on light and sound technologies and hybrid combinations thereof. In particular, the lab develops new systems for optoacoustic imaging and interferometric detectors of ultrasound.

Here are a few of the cutting-edge research subjects we are currently exploring in our lab:

Single Pixel Imaging at MHz Rates via Cyclic Hadamard Patterns- In this project we focused on speeding up single pixel imaging systems and until now managed to achieve modulation rates of 2.4 MHz. This is two orders of magnitudes above the currently available modulation rates! Also, we developed algorithms for correcting motion errors that occur when moving faster than the imaging rate.

Detection of ultrasound via optical interferometry- The detection of ultrasound is conventionally performed by using piezoelectric transducers. Despite the ubiquity of this approach, it suffers from several drawbacks that limit its application. In particular, in the field of optoacoustic imaging, the opacity of piezoelectric materials in use puts constraints on possible illumination patterns.

Optoacoustic tomography: Systems and theory- Optoacoustic tomography (OAT), also known as photoacoustic tomography, is a hybrid imaging modality that enables the visualization of optical contrast with high resolution at tissue depths in which light propagation is diffusive.
