| titleOfInvention | Sparsity self-adaptive set orthogonal matching pursuit excitation fluorescence tomography reconstruction method |
| abstract | The invention belongs to the field of optical molecular images, and particularly relates to a sparsity adaptive set orthogonal matching pursuit excitation fluorescence tomography reconstruction method, aiming at solving the problems of over-sparse area, discontinuous space and under-robust process existing in tumor distribution solving by sparse constraint optimization in the prior art. The method comprises the following steps: segmenting biological CT three-dimensional data, discretizing finite elements, and fusing with biological body surface fluorescence excitation image data; establishing a model according to the fused body surface excitation fluorescence light intensity distribution information; dividing a model and constructing a local space continuity constraint condition; and integrating L1 norm sparsity and carrying out iterative solution to obtain the convergence distribution condition of the probes in the biological tumor region. According to the method, a brand-new space structure sparse regularization item is constructed by fusing space structure constraint and sparse constraint, and the problems of over-sparse area, discontinuous space, under-robust process and the like caused by solving tumor distribution based on sparse constraint are mainly solved. |
