Periodic Report Summary 2 - MSOT (Quantitative real-time multi-spectral optoacoustic tomography)
The projects' two major goals were: reducing the data acquisition time for Multi-spectral-optoacoustic-tomography (MSOT) and improving quantification in image formation. In both areas, significant progress has been made. However, some specific details in the implementation were altered to exploit new opportunities and accommodate unforeseen complications. The first aim of the project was to design a new optoacoustic data acquisition system that could significantly reduce the time required for performing MSOT. The second aim of the project involves developing numerical algorithms for the formation of quantified optoacoustic images from the measured dataset. The reconstruction algorithm developed in the first year is based on building a matrix relation, whose inversion yields the optoacoustic image. In the second year of the project, a new method for efficient inversion of the model matrix was developed.
