Dynamic particle enhancement in limited-view optoacoustic tomography
X L Dean-Ben, L Ding, D Razansky
Limited-view artefacts are commonly present in optoacoustic tomography images, mainly due to practical geometrical and physical constraints imposed by the imaging systems as well a…
Eigenspectra optoacoustic tomography achieves quantitative blood oxygenation imaging deep in tissues
Stratis Tzoumas, Antonio Nunes, Ivan Olefir +6
Light propagating in tissue attains a spectrum that varies with location due to wavelength-dependent fluence attenuation by tissue optical properties, an effect that causes spectra…
Visual Quality Enhancement in Optoacoustic Tomography using Active Contour Segmentation Priors
Subhamoy Mandal, Xosé Luís Deán-Ben, Daniel Razansky
Segmentation of biomedical images is essential for studying and characterizing anatomical structures, detection and evaluation of pathological tissues. Segmentation has been furthe…
Stability of non-isolated asymptotic profiles for fast diffusion
Goro Akagi
The stability of asymptotic profiles of solutions to the Cauchy-Dirichlet problem for Fast Diffusion Equation (FDE, for short) is discussed. The main result of the present paper is…
Influence of the absorber dimensions on wavefront shaping based on volumetric optoacoustic feedback
X. L. Dean-Ben, H. Estrada, A. Ozbek +1
The recently demonstrated control over light distribution through turbid media based on real-time three-dimensional optoacoustic feedback has offered promising prospects to interfe…
Multiscale edge detection and parametric shape modeling for boundary delineation in optoacoustic images
Subhamoy Mandal, Viswanath Pamulakanty Sudarshan, Yeshaswini Nagaraj +2
In this article, we present a novel scheme for segmenting the image boundary (with the background) in optoacoustic small animal in vivo imaging systems. The method utilizes a multi…
