Abstract

A method of multi-spectral opto-acoustic tomography (MSOT) imaging of a target tissue including a target tissue biomarker comprises the steps of illuminating the target tissue with an illumination device emitting at least one pulsed illumination pattern at several illumination wavelengths, detecting pressure signals from the target tissue biomarker with a detector device, wherein the pressure signals being produced in the target tissue in response to the said illumination, and reconstructing a quantitative tomographic image of a distribution of the target tissue biomarker in the target tissue, wherein the pressure signals are analyzed using a photon propagation model, which depends on an illuminating light fluence in the target tissue and on the illumination wavelengths, at least one spectral processing scheme, and an inversion scheme providing the tomographic image. Furthermore, an imaging device for multi-spectral opto-acoustic tomography is described.

Description

Technical field [0001] The present invention relates to methods and devices for quantitative three-dimensional sensing and imaging of target tissue markers, which are especially used in clinical, small animal and small biological imaging applications using multi-wavelength illumination. Background technique [0002] Non-invasive imaging of in vivo functions and molecular markers is an emerging and important capability in biological discovery, drug discovery, and some clinical applications, which goes beyond anatomical imaging and delayed disease identification. Another important prospect of visualizing tissue biomarkers is the ability to detect and quantify the treatment response in vivo by monitoring specific major molecules or downstream targets. The therapeutic effect can then be dynamically detected on the time scale from hour to day. This ability is in contrast to current mainstream medical care with traditional late-stage end-point efficacy, and this practice often comprom...
