The Discrete Radon Transform and Its Approximate Inversion Via Linear Programming
Let S be a jinite subset of a lattice and let us(L), the number of points of S IL for each line L, denote the discrete Radon transform of S. The problem is to reconstruct S from a knowledge (possibly noisy) of the restriction of US to a subset Y of the set of all lines in any of a few given directions through the lattice. Reconstructing a density from its line integrals is a well-understood pro...
متن کاملA Fast and Accurate Multilevel Inversion of the Radon Transform
A number of imaging technologies reconstruct an image function from its Radon projection using the convolution backprojection method. The convolution is an O(N2 logN) algorithm, where the image consists of N×N pixels, while the backprojection is an O(N3) algorithm, thus constituting the major computational burden of the convolution backprojection method. An O(N2 logN) multilevel backprojection ...
متن کاملFast Inversion of the Radon Transform Using Log-polar Coordinates and Partial Back-Projections
In this paper a novel filtered back-projection algorithm for inversion of a discretized Radon transform is presented. It makes use of invariance properties possessed by both the Radon transform its dual. By switching to log-polar coordinates, both operators can be expressed in a displacement invariant manner. Explicit expressions for the corresponding transfer functions are calculated. Furtherm...
متن کاملFast numerical inversion of the attenuated Radon transform with full and partial measurements
We propose a numerical method to simulate and invert the two-dimensional attenuated Radon transform (AtRT) from full (360◦) or partial (180◦) measurements. The method is based on an extension of the fast slant stack algorithm developed for the Radon transform. We show that the algorithm offers robust and fast inversion of the AtRT for a wide class of synthetic sources and absorptions. The compl...
متن کاملDiscrete-Time Exact and Approximate Dynamic Inversion for Settle Performance
Single-track hard disk drive (HDD) seek performance is measured by settle time, ts, defined as the time from the arrival of a seek command until the measured position reaches and stays within an acceptable distance from the target track. In this paper, we show the effective use of feedforward dynamic inversion, coupled with an aggressive desired trajectory yd, to achieve high performance settle...
