1. A thermoacoustic tomograph for imaging an object, comprising:

  • at least one excitation source configured to thermally excite the object;

    at least one large-area or integrating line detector for detecting acoustic waves caused by the object upon excitation thereof by said source, said at least one detector having a size chosen in dependence on a distance between said detector and a point of the object that is furthest away from said detector, wherein d denotes the distance between said detector and a point of the object that is furthest away from said detector, and wherein said detector has at least one dimension with an extent of at least √

    {square root over (8)}·

    d;

    a movement device for moving the object and/or the at least one detector relative to one another; and

    a device connected to said detector for reconstructing an image of the object from the acoustic waves detected by said detector in dependence on a respective position of the object.
