Abstract: The present disclosure relates to a handheld device for optoacoustic imaging of an object and a corresponding method comprising an irradiation unit configured for irradiating the object with electromagnetic radiation, for example light, and a detector unit for detecting acoustic, for example ultrasonic, waves which are generated in the object upon irradiation with electromagnetic radiation. In order to facilitate three-dimensional multispectral imaging in real-time, which allows not only imaging of dynamic anatomical, functional and molecular phenomena in the object but also avoids multiple motion- and limited-view-related image artifacts and thus facilitates quantitative image acquisition, in some embodiments, the detector unit comprises a two-dimensional array of a plurality of detector elements which may be arranged along a first surface.

Abstract: The invention includes a device and a method for hybrid optoacoustic and ultrasonographic imaging of an object. The device comprises: an irradiation unit configured to irradiate the object with electromagnetic radiation; first transducer elements configured to detect ultrasound waves generated in the object upon irradiating the object with the electromagnetic radiation; second transducer elements configured to detect ultrasound waves reflected and/or transmitted by the object; a surface comprising at least one first surface segment, on which the first transducer elements are arranged, and at least one second surface segment, on which the second transducer elements are arranged. The first surface segment and/or the second surface segment have a curved shape. The first transducer elements have a first size and pitch and second transducer elements have a second size and pitch, wherein the first pitch and second pitch are different and/or the first size and second size are different.
