Abstract
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 √{square root over (8)}·d, where d denotes the maximum distance from a point of the object to be imaged to the detector.
