Embodiment Construction

[0041] figure 1 A cross-sectional side view of a first embodiment of a handheld device 10 according to the invention is shown. The handheld device 10 comprises a container 11 , wherein a recess 12 with a surface 17 is provided in the container 11 . The container 11 is preferably made of metal. The recess 12 in the container 11 is shaped as part of a sphere, in particular a cap or part of an ellipsoid.

[0042] An array 14 of ultrasound detector elements is provided in the recess 12 . In the example given, the detector element array 14 is arranged on or along the surface 17 of the recess 12 . As is evident from the figure, the array is provided in the bottom region of the recess 12 . The detector element array 14 is preferably a linear array.

[0043] The recess 12 has a hole in which the end face of the fiber bundle 16 is provided. The end faces of the fiber bundle 16 include a plurality of end faces of a plurality of individual optical fibers 17 of the fiber bundle, whe...

Abstract

The invention relates to a handheld device (1) for photoacoustic imaging of objects and a corresponding method, the handheld device comprising an illumination unit (2b) for illuminating the object with electromagnetic radiation (5), in particular light, and for detecting Acoustic detector unit (1a, 1b) for acoustic waves, in particular ultrasonic waves, generated in an object after irradiation with electromagnetic radiation (5), wherein the detector unit (1a, 1b) comprises an array of detector elements (1a). In order to ensure the acquisition of high-quality tomographic photoacoustic imaging from different depths within the object with a simple overall design, the handheld device (19) is provided with a recess (6), wherein the illumination unit (2b) is provided in the recess (6) ) and an array of detector elements (1a), wherein the detector elements are arranged in the recesses (6) such that the surface normals of at least a portion of the detector elements point towards a region of interest in or on the object.

Description

technical field [0001] The invention relates to a handheld device and a method for photoacoustic imaging of objects according to the independent claims. Background technique [0002] Photoacoustic imaging is based on the photoacoustic effect, according to which ultrasound waves should be generated due to the absorption of electromagnetic radiation by an object (eg biological tissue) and the subsequent thermoelastic expansion of the object. [0003] Photoacoustic imaging of biological tissue is based on spectrally dependent light absorption to provide a unique combination of high spatial resolution and rich contrast. Thus techniques such as multispectral optoacoustic tomography (MSOT) can simultaneously give anatomical, functional, and molecular contrast images by exciting tissue at multiple wavelengths of light, enabling applications in molecular imaging and diagnostics, drug development Potential applications in and therapy monitoring become possible.
