Abstract: Methods and systems for determining a region of interest in ultrasound data are provided. One method includes defining an ROI within an acquired ultrasound data set and identifying a plurality of different image planes within the acquired ultrasound data set. The method further includes determining a significant edge from at least one border of the ROI based on the plurality of image planes and adjusting the ROI based on the determined significant edge.

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.
