Accurate and fast reconstruction for bioluminescence tomography based on adaptive Newton hard thresholding pursuit algorithm

Abstract: As a promising noninvasive medical imaging technique, bioluminescence tomography (BLT) dynamically offers three-dimensional visualization of tumor distribution in living animals. However, due to the high ill-posedness caused by the strong scattering property of biological tissues and the limited boundary measurements with noise, BLT reconstruction still cannot meet actual preliminary clinical application requirements. In our research, to recover 3D tumor distribution quickly and precisely, an adaptive Newton h… Show more

“…Progress in the field of BLI has been made on the one hand at the technical level, notably through the development of tomographic procedures and the correlation of these with CT and MRI images [ 5 , 6 ]. On the other hand, reconstruction methods that aim to solve the inverse problem, either mathematically or, more recently, using artificial intelligence [ 7 , 8 ], represent another area of new developments. These methods, however, are based on assumptions regarding optical parameters and anticipated tissue behavior.…”

“…Recently, the iterative hard thresholding (IHT) algorithm has developed to solve the problems related to L 0 -norm regularization optimization [33] and has been successfully applied in many areas of biomedical imaging. For example, Wang et al have used an adaptive Newton IHT to improve the performance of bioluminescence tomography [34]. Yuan et al have applied the IHT algorithm to solve the inverse problem of Fluorescence molecular tomography [35].…”

“…Therefore, the geometry and material properties of the structures on a wafer are approximately known beforehand, but not exactly due to process variations. To extract these aspects of the produced structures precisely, the estimated spatial permittivity distribution is adjusted such that it minimizes the differences between the measurements and the output of the computational model [3][4][5][6]. This is a so-called inverse scattering problem.…”
