Dynamic PhotoAcoustic Tomography
PhotoAcoustic tomography (PAT) has become a powerful new imaging technique combining high-resolution and novel contrast mechanisms as an example of so-called "Coupled Physics Imaging" methods. As in many imaging modalities there is a trade-off between acquisition speed and resolution. This is especially relevent when considering time-varying imaging (4D) and multispectral imaging (5D). In this talk we present recent developments in i) a compressed sensing approach to data acqusition using novel multi-detector/random sampling schemes and ii) the application of novel spatio-temporal regularisation methods.
