An Optical Projection Tomography (OPT) system was developed and optimized to image 3D tissue engineered products based in hydrogels. We develop pre-reconstruction algorithms get the best result from reconstruction procedure, which include correction of illumination determination sample center rotation (CoR). Existing methods for CoR on detection maximum variance reconstructed slices failed, so we a new search method sharpest local maximum. show capabilities give quantitative information...
Electrical impedance tomography (EIT) is an imaging method that could become a valuable tool in multimodal applications. One challenge simultaneous typically the EIT electrodes cover large portion of object surface. This paper investigates feasibility rotational (rEIT) applications where only limited angle surface object. In studied rEIT, rotated full 360° during set measurements to increase information content data. We call this approach revolution rEIT (LAFR-rEIT). test LAFR-rEIT setups...
Imaging of tissue engineered three-dimensional (3D) specimens is challenging due to their thickness. We propose a novel multimodal imaging technique obtain multi-physical 3D images and the electrical conductivity spectrum specimensin vitro.We combine simultaneous recording rotational multifrequency impedance tomography (R-mfEIT) with optical projection (OPT). Structural details specimen provided by OPT are used here as geometrical priors for R-mfEIT.This data fusion enables accurate...
Induced pluripotent stem cell (iPSC) technology enables differentiation of human hepatocytes or hepatocyte-like cells (iPSC-HLCs). Advances in 3D culturing platforms enable the development more vivo-like liver models that recapitulate complex architecture and functionality better than traditional 2D monocultures. Moreover, within liver, non-parenchymal (NPCs) are critically involved regulation maintenance hepatocyte metabolic function. Thus, combining culture co-culturing various types...
Determining the center of rotation is essential for high quality 3D reconstruction in Optical Projection Tomography. In order to get an algorithm that can be used all types samples, a new search method was developed.
