Beatty-(12)
Reconstruction of magnetic resonance images from
data not falling on a Cartesian grid is a Fourier inversion problem
typically solved using convolution interpolation, also known as
gridding. Gridding is simple and robust and has parameters,
the grid oversampling ratio and the kernel width, that can be
used to trade accuracy for computational memory and time
reductions. We have found that significant reductions in computation
memory and time can be obtained while maintaining high
accuracy by using a minimal oversampling ratio, from 1.125 to
1.375, instead of the typically employed grid oversampling ratio
of two. When using a minimal oversampling ratio, appropriate
design of the convolution kernel is important for maintaining high
accuracy

利用kalman滤波算法对状态空间描述的位移测量系统进行了滤波处理,对系统输出的真实位移、测量位移和滤波位移进行了对比,显示了kalman滤波算法较好的滤波性能。(Displacement measurement system described by the equation of states were filtered by Kalman filter algorithm. The output of the system, including the real displacement, measuring displacement and filtering displacement were compared, and the results showed the great performance of Kalman filter algorithm.)
