  • Publication number: 20150366458
    Abstract: An imaging apparatus (100), configured for thermoacoustic tomographic imaging a region of interest (2) in an object (1), comprises a source device (10) being arranged for emitting an electromagnetic energy input into the region of interest (2), a detector device (20) being arranged for detecting mechanical wave response signals generated in the region of interest (2) along multiple angular projection directions in response to the electromagnetic energy input, and an image data acquisition and processing device (30) being arranged for providing tomographic image data representing the image of the region of interest (2) on the basis of the mechanical wave response signals, wherein the source device (10) is adapted for continuously emitting the electromagnetic energy input with a predetermined input modulation, and the image data acquisition and processing device (30) is adapted for converting the mechanical wave response signals into the frequency domain and for performing data processing and image reconstructi
