A method for high resolution photoacoustic imaging in scattering media using structured illumination may include illuminating a sample of an absorption object with structured illumination, including illuminating the sample with multiple different speckle patterns at different times. The method may also include detecting multiple photoacoustic signals generated by the absorption object in response to illumination with the different speckle patterns to generate multiple photoacoustic responses. The method may also include reconstructing an absorber distribution of the absorption object by exploiting joint sparsity of sound sources in the plurality of photoacoustic responses.

High resolution photoacoustic imaging in scattering media using structured illumination

A thermoacoustic tomographic method for imaging an object, wherein the object is thermally excited by a source and the acoustic waves from the object, which are caused by the thermal excitation, from different directions of the object are detected using at least one detector and an image of the object is reconstructed from the detected acoustic waves and the positional information, wherein the acoustic waves detected by the detector are integrated at least in one direction over a length of at least &#x221a;{square root over (8)}&#xb7;d, where d denotes the maximum distance from a point of the object to be imaged to the detector.
