Reconstruction — NOTOC Reconstruction may refer to:Politics, history and sociology*Postwar reconstruction. **Reconstruction era of the United States, the period between 1865 to 1877 when the US government focused on resolving the consequences and aftermath of the … Wikipedia
Reconstruction filter — In a mixed signal system (analog and digital), a reconstruction filter (or anti imaging filter) is used to construct a smooth analogue signal from the output of a digital to analogue converter (DAC) or other sampled data output device.ampled data … Wikipedia
algorithm — A systematic process consisting of an ordered sequence of steps, each step depending on the outcome of the previous one. In clinical medicine, a step by step protocol for management of a health care problem … Medical dictionary
algorithm — n. a sequential set of instructions used in calculations or problem solving. A reconstruction algorithm is a complex mathematical formula used by a computer to construct images from the data acquired by CT, MRI, or other scanners. A diagnostic… … The new mediacal dictionary
Difference-map algorithm — Iterations 0, 100, 200, 300 and 400 in the difference map reconstruction of a grayscale image from its Fourier transform modulus The difference map algorithm is a search algorithm for general constraint satisfaction problems. It is a meta… … Wikipedia
Signal reconstruction — In signal processing, reconstruction usually means the determination of an original continuous signal from a sequence of equally spaced samples.This article takes a generalized abstract mathematical approach to signal sampling and reconstruction … Wikipedia
Expectation-maximization algorithm — An expectation maximization (EM) algorithm is used in statistics for finding maximum likelihood estimates of parameters in probabilistic models, where the model depends on unobserved latent variables. EM alternates between performing an… … Wikipedia
Difference map algorithm — The difference map algorithm is a search algorithm for general constraint satisfaction problems. It is a meta algorithm in the sense that it is built from more basic algorithms that perform projections onto constraint sets. From a mathematical… … Wikipedia
CARET (Computerized Anatomical Reconstruction and Editing Toolkit) — CARET (Computerized Anatomical Reconstruction Toolkit) is a software application for the structural and functional analysis of the cerebral and cerebellar cortex. CARET is developed in the Van Essen Laboratory in the Department of Anatomy and… … Wikipedia
Iterative reconstruction — is a method or group of algorithms used to reconstruct 2D and 3D images from the projections of an object. The technique differs greatly from the more ubiquitous filtered back projection (FBP) method. In X ray computed tomography, this method is… … Wikipedia
