Image reconstruction

Physics in Medicine and Biology, 2006
We give an overview of the role of Physics in Medicine and Biology in the development of tomographic reconstruction algorithms. We focus on imaging modalities involving ionizing radiation, CT, PET and SPECT, and cover a wide spectrum of reconstruction problems, starting with classical 2D tomography in the 1970s up to 4D and 5D problems involving ...

Reconstruction in diffraction imaging

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1989
The problem of reconstruction in imaging systems that are modeled using the Helmholtz wave equation (diffraction imaging) is addressed. A spectral analysis of the available diffraction data is presented to help develop algorithms and constraints on a diffraction imaging system's parameters for accurate reconstruction of the desired image.

Image reconstruction in intravascular photoacoustic imaging

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2011
Intravascular photoacoustic (IVPA) imaging is a technique for visualizing atherosclerotic plaques with differential composition. Unlike conventional photoacoustic tomography scanning, where the scanning device rotates around the subject, the scanning aperture in IVPA imaging is enclosed within the imaged object.

Imaging breast augmentation and reconstruction

The British Journal of Radiology, 2008
Breast augmentation and breast reconstruction, either immediate or delayed, are increasingly common operations. All radiologists need to be able to recognize the normal appearances of the more commonly used implants on various imaging modalities, and breast radiologists in particular are facing new challenges when imaging the women involved.

Computational methods for image reconstruction

NMR in Biomedicine, 2016
Reconstructing images from indirect measurements is a central problem in many applications, including the subject of this special issue, quantitative susceptibility mapping (QSM). The process of image reconstruction typically requires solving an inverse problem that is ill‐posed and large‐scale and thus challenging to solve. Although the research field

Image reconstruction of tubulin hoops

Journal of Ultrastructure Research, 1981
The two-dimensional projected structure of tubulin hoops is reconstructed at a resolution of 1.6 nm from electron images of negatively stained specimens taken at a low electron dose. Like most tubulin aggregates, the hoops consist of protofilaments. A unique feature of hoops is the grouping of protofilaments into triplets.
