As introduced in Chapter 3, inverse synthetic aperture radar (ISAR) data are arranged in a 2-D matrix, where the number of range cells is in its row and the number of pulses is in its column, or vice versa. To reconstruct an ISAR range-Doppler image, we first take range compression to obtain ISAR range profiles, which is a sequence of consecutive range

Motion compensated local tomography
Inverse Problems, 2008In this paper we develop local tomography (LT) for image reconstruction from motion contaminated data. It is assumed that motion is known. We propose a new LT function f?, which is related to an original object f via an operator : . Because of motion, may fail to be a pseudo-differential operator (PDO). We obtain the conditions that guarantee that is

The Motion Compensation Hypothesis
1997Motion compensation is the defining factor of both MPEG and H.261/H.263 compression standards. Without it, these techniques would not achieve compression ratios anywhere close to their current range.

A method and system for motion tracking of a target organ are provided. A tracking needle is partially inserted into an organ. The needle has a sensor element for obtaining continuous needle orientation information which can be used to determine organ motion due to respiration during percutaneous needle insertion.
