Reconstructed Wavefield Imaging
Proceedings, 2017Summary We propose and implement a novel imaging method, which is referred to as reconstructed wavefield imaging (RWI). The idea of RWI is to solve a partial differential equation (PDE) constrained optimization problem for reconstructing a more reliable source wavefield that satisfies the two-way wave equation and also best fits the recorded data at ...

We have seen that, when complete continuous X-ray data are available, then an attenuation-coefficient function f(x, y) can be reconstructed exactly using the filtered back-projection formula, Theorem 6.2.

Contributions to image reconstruction
1977The problem of image reconstruction from indirect measurements is considered. Reconstruction methods for the following types of measurement are presented in detail: (a) Radiant intensity at the image plane of the transmission electron microscope. (b) Radiant intensity of X-ray diffraction from paracrystalline and fibrous macromolecular specimens.

This chapter outlines the fundamentals of several image reconstruction approaches currently in use in X-ray tomography at synchrotron radiation facilities and at industrial X-ray CT scanners, clarifying both their proper use and points of caution in image reconstruction.

Reconstruction of polygonal images
Journal of Applied Statistics, 1989Let T be a two-dimensional region, and let X be a surface dejined on T. The values of X on T, constitute an image, or pattern. The true value of X at any point on T cannot be directly observed, but data can be recorded which provide information about X.

Algorithms for Image Reconstruction
2010Three-dimensional (3D) imaging is becoming one of the most important applications of radioactive materials in medicine. It offers good spatial resolution, a 3D insight into the human body, and a high sensitivity in the picomolar range because markers for biological processes can be detected well when labeled with radioactive materials. In addition, the

Reconstructive Elasticity Imaging
1995Changes in soft tissue elasticity are usually related to some abnormal, pathological process. Because the Young’s modulus can differ by orders of magnitude between soft tissues,l there has been consistent interest in tissue elasticity. Unfortunately, no imaging modality, including ultrasound, nuclear magnetic resonance (MRI) and computed tomography (CT)

Image Reconstruction with VITRUV
2007Imaging in optical interferometry is definitively the path to follow with the advent of interferometers with large aperture. The VLTI has an important way to play, since it is a unique interferometric site with 4 relocable 2m-class telescopes in addition to the 4 Very Large Telescopes.
