摘要:
The invention relates to a thermoacoustic tomographic method and a thermoacoustic tomograph (1), for imaging an object (2) with at least one source (3), for the thermal stimulation of the object (2) and at least one detector (5), for recording the acoustic waves (4) from the object (2) caused by the stimulation, comprising an arrangement (7), for displacing the object (2) and/or the at least one detector (5) relative to each other and an arrangement (8), for the reconstruction of the object (2) from the recorded acoustic waves (4), depending on the actual position of the object (2). According to the invention, such a method or arrangement for reconstruction of the object (2) with the least possible algorithmic complexity but with the highest possible resolution may be achieved, whereby the at least one detector (5) has a size in at least one dimension of at least v8.d, where d gives the maximum separation of a point of the object (2) for imaging from the detector (5).
