WebAssuming x is sparse (which is not wrong in many cases), makes things easier. So let's say our observed data is y, and we want to get x. The problem is then: x = argmin { L2 [ S (F (x)) - y ] + λ * L1 [x] } where S is a sampling function, F is the fourier transform, x is the sparse vector, y is the response from the telescope, L2 and L1 are 1 ...

WebCoherent plane-wave compounding (CPWC) enables high-frame-rate ultrasound imaging, but the imaging quality is mainly determined by the beamforming method. Covariance-matrix-based statistical beamforming (CMSB) was previously proposed for synthetic aperture ultrasound imaging, which provides notable improvements in resolution and contrast over … WebApr 9, 2024 · The concept of Intravoxel Incoherent Motion ... 58 ms, TE 13b = 65 ms, TR = 3300 ms, flip angle = 90 , in-plane resolution = 1.14 × 1.14 mm, slice thickness = 4 mm, matrix size = 200 × 200 × 19, slice gap = 0.8 mm) with full-brain coverage.
