Ultrasonic tissue characterization
TL;DR: In this paper, a statistical analysis is employed to estimate the scatterer number density (SND) of tissues, which incorporates measurements of both the statistical moments of the backscattered signals and the point spread function of the acoustic system.

Delta-sigma oversampled ultrasound beamformer with dynamic delays
Steven R. Freeman,M.K. Quick,M.A. Morin,R.C. Anderson,C.S. Desilets,Thomas E. Linnenbrink,Matthew O'Donnell +6 more
TL;DR: The principles of oversampling are exploited in a simple beamforming architecture using a single bit delta-sigma (/spl Delta/C) analog to digital converter (A/D) on every channel to provide adequate delay accuracy for high quality beamforming using elementary sample manipulations.

Linear prediction: A tutorial review
TL;DR: This paper gives an exposition of linear prediction in the analysis of discrete signals as a linear combination of its past values and present and past values of a hypothetical input to a system whose output is the given signal.

A new microscopic principle.
TL;DR: An improvement of the resolution by one decimal wotild require a correction of the objective to four decimals, a practically hopeless task.

A new algorithm in spectral analysis and band-limited extrapolation
TL;DR: In this paper, a new algorithm is proposed for computing the transform of a band-limited function, which is a simple iteration involving only the fast Fourier transform (FFT), and it is shown that the effect of noise and the error due to aliasing can be controlled by early termination of the iteration.

The Reconstruction of a Three-Dimensional Structure from Projections and its Application to Electron Microscopy
TL;DR: In this paper, the Fourier transform is used to combine data from a number of different views of a transmission electron micrograph to reconstruct a 3D image of a given particle to a given degree of resolution.

A Filtered Backpropagation Algorithm for Diffraction Tomography
TL;DR: The reconstruction algorithm is derived for parallel beam transmission computed tomography through two-dimensional structures in which diffraction of the insonifying beam must be taken into account and is applicable to diffraction tomography within either the first Born or Rytov approximations.
