Tues-A17_01-Beatty-Gridding
In this session, I will focus on the gridding method for fast image reconstruction from non-
Cartesian data [1-5]. While gridding is not the only game in town, it is the reconstruction of
choice when reconstruction time is an issue. Other reconstruction techniques include rBURS
[6] and non-Cartesian iterative methods [7,8]. Non-Cartesian iterative methods generally use
gridding and inverse gridding as their core operation, so even when gridding is not the right
solution for an application, an understanding of gridding can be useful.
I will cover the main steps of the gridding algorithm and then discuss some implementation tips
that can signicantly reduce the computation time. Finally, I will present some illustrations and
viewpoints that I have found to aid in an intuitive understanding of the gridding method, which
can be helpful when designing the density compensation function and judging the appropriateness
of gridding as a solution for a particular application.

Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer (an eye or a camera) and the scene.[2][3] The concept of optical flow was first studied in the 1940s and ultimately published by American psychologist James J. Gibson[4] as part of his theory of affordance. Optical flow techniques such as motion detection, object segmentation, time-to-collision and focus of expansion calculations, motion compensated encoding, and stereo disparity measurement utilize this motion of the objects surfaces and edges.[5][6]
