Nuts & Bolts of Advanced Imaging - Parallel Imaging
نویسنده
چکیده
OBJECTIVES: This course aims to describe the effects of colored noise in the parallel MRI [1– 3] experiment and how to perform a reconstruction, which takes the noise distribution into consideration. Techniques for SNR scaled reconstruction [4] are described for Cartesian and non-Cartesian imaging. The course will also describe iterative reconstruction algorithms and their regularized forms. Software for all the described reconstruction processes will also be introduced.

Nuts & Bolts of Advanced Imaging: Parallel Imaging Reconstruction Design
• Most non-iterative reconstruction methods can be separated into a calibration step that generates channel combination and unaliasing coefficients followed by a step that applies these coefficients to create reconstructed images. • Maps of image shading, noise amplification and aliasing energy can be created to better assess the image quality achieved by a reconstruction pipeline. • Complete c...
متن کاملMatching Nuts and Bolts in O(n log n) Time
Given a set of n nuts of distinct widths and a set of n bolts such that each nut corresponds to a unique bolt of the same width, how should we match every nut with its corresponding bolt by comparing nuts with bolts? (No comparison is allowed between two nuts or two bolts.) The problem can be naturally viewed as a variant of the classic sorting problem as follows. Given two lists of n numbers e...

The problem of matching nuts and bolts is the following Given a collection of n nuts of distinct sizes and n bolts such that there is a one to one correspondence between the nuts and the bolts nd for each nut its corresponding bolt We can only compare nuts to bolts That is we can neither compare nuts to nuts nor bolts to bolts This humble restriction on the comparisons appears to make this prob...
متن کاملMatching Nuts and Bolts Extended Abstract
We describe a procedure which may be helpful to any disorganized carpenter who has a mixed pile of bolts and nuts and wants to nd the corresponding pairs of bolts and nuts. The procedure uses our (and the carpenter's) ability to construct e ciently highly expanding graphs. The problem considered is given a collection of n bolts of distinct widths and n nuts such that there is a 1-1 corresponden...
متن کاملMatching Nuts and Bolts Optimally∗
The nuts and bolts problem is the following : Given a collection of n nuts of distinct sizes and n bolts of distinct sizes such that for each nut there is exactly one matching bolt, find for each nut its corresponding bolt subject to the restriction that we can only compare nuts to bolts. That is we can neither compare nuts to nuts, nor bolts to bolts. This humble restriction on the comparisons...
