Title:
Optoacoustic image reconstruction and system analysis for finite-aperture detectors under the wavelet-packet framework. 
Abstract:
In optoacoustic tomography, detectors with relatively large areas are often employed to achieve high detection sensitivity. However, spatial-averaging effects over large detector areas may lead to attenuation of high acoustic frequencies and, subsequently, loss of fine features in the reconstructed image. Model-based reconstruction algorithms improve image resolution in such cases by correcting for the effect of the detectors aperture on the detected signals. However, the incorporation of the de...    »
