Project Details

Project:
Fast semi-analytical acoustic inversion for quantitative optoacoustic tomography

Supervisors:
Prof. Dr. Vasilis Ntziachristos
Prof. Dr. med. Markus Schwaiger

Start of PhD-work at GSISH:
October 2010

Project Description:
Optoacoustic (or photoacoustic) tomography is a hybrid imaging modality that has recently demonstrated unprecedented high-resolution imaging of chromophore distribution and vasculature deep in tissues of small animals. Optoacoustic imaging relies on detection of ultrasonic signals induced by absorption of pulsed light. The amplitude of the generated broadband ultrasound waves reflects local optical absorption properties of tissue. Since scattering of ultrasonic waves in biological tissues is extremely weak, as compared to that of light, biomedical optoacoustic imaging combines high optical absorption contrast with good spatial resolution limited only by ultrasonic diffraction. Major focus of the project is the development of advanced imaging algorithms including multi-spectral real-time imaging. The resulting image reconstruction method is intended to significantly improve existing techniques. Also part of the project is the demonstration of the new method with experimental phantoms and pre-clinical data.
