Magnetic particle imaging (MPI) uses nonlinear response signals to noninvasively detect magnetic nanoparticles in space, and its quantitative properties hold promise for future precise treatments. In reconstruction, the system matrix based method necessitates suitable regularization terms, such as Tikhonov or non-negative fused lasso (NFL) regularization, stabilize solution. While NFL offers clearer edge information than it carries a biased estimate of <italic...
We review the current state-of-the-art of bioluminescence tomography (BLT) imaging, which is an emerging technique for monitoring and assessment biological processes in vivo. The aim BLT to reconstruct 3-D distribution internal bioluminescent source using boundary measurements acquired by a imaging system. Thus, becomes task solving inverse problem with appropriate photon propagation model. In this paper, we discuss recent advances models transport, detail techniques reconstructions....
Bioluminescence tomography (BLT) has become a powerful tool for whole-body small animal imaging. In this contribution, an adaptive improved element free Galerkin method (IEFGM) is presented to perform quantitative reconstruction of the internal light source using quasi- or multi-spectral information, which not only can avoid time-consuming mesh generation but also reduce ill-posedness BLT effectively. algorithm, be largely enhanced by technology based on posteriori error estimation. Finally,...
Magnetic particle imaging (MPI) is a rapidly developing medical modality, which uses the nonlinear response of superparamagnetic iron oxide nanoparticles to applied magnetic field image their spatial distribution. Background signal main source artifacts in MPI, mainly includes harmonic interference and Gaussian noise. For different sources noise, existing methods directly process time domain achieve enhancement or construct system function by frequency obtain high-quality reconstructed...
Imaging modality of radionuclides has been enriched by an optical approach, Cerenkov luminescence tomography (CLT). Referred to the traditional radionuclide imaging, such as positron emission (PET) or single photon computed (SPECT), any incremental improvement CLT imaging is consistent with application information needs. In this contribution, paper presents l <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> -regularized method for...
Odor pollution means a distinctive gas that is offensively unpleasant and harmful for the living conditions, not only disturbing social activities but also being harm human. For character of odor pollution, kind detecting system based on photoionization detector (PID) has been developed. The capillary column used as separate device PID detector. From stability experiment sensor, standard deviation 5.88×10 -3 , relative 0.14%. Furthermore, experimental results sample calibration illustrated...
A kind of online or portable odor detector is needed for continuously monitoring the concentration and tracing source which one atmosphere pollution. Combining gas chromatograph (GC) micro-fluidic chip technology, we present a detecting system using separator photo ionization (PID) sensor. The 115×60×6mm chip, etched micro channel 1mm diameter 1.8m length inside, filled by polyethylene glycol as stationary phase according to type character odor. Respectively stainless steel packed columns,...
Tomographic bioluminescence imaging suffers from poor robustness, since it is severely affected by selection of regularization parameter (RP) and initialization for source distribution. In this paper, a global-inexact-Newton based reconstruction methodology, which regularized dynamic sparse term, demonstrated in vivo tomographic imaging. The novel method can enhance higher reliability efficiency. Mouse experimental reconstructions were performed to validate the proposed method. These results...
Niche Genetic Algorithm (NGA) is proposed to recognize a disconnected nonparametric curve from noisy binary image. The fitness function used in the NGA derived hypothesis: Human Visual Tradition Model (HVTM). Sharing based niche technique and elite-preserving strategy are utilized preserve population variety for converging at global optimum. It has advantage of using method extract curves image other than parametric method, which Hough Transform (HT) can conclude. extracted by verified...
