Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional image reconstruction is a scientific undertaking of fundamental importance spanning numerous fields including molecular biology, physical chemistry, materials science, physics, and medicine across length scales ranging from the astronomical to the atomic. Despite the broad-reaching nature of this topic, the underlying mechanics and core mathematics are shared, with the ultimate objective being achieving an interpretable representation of some 3D structure from a series of 2D measurements, and, at the time of this writing, at least three Nobel prizes have been awarded for quantitative 3D imaging applications. Although enormous strides have been made over the past several decades in instrumentation, sample preparation, and experimental methodology, comparatively few improvements have been made to tomgraphic reconstruction algorithms. With the ever-increasing availability of high-performance computing resources, a more compelling argument than ever before can be made for the value of developing novel algorithms and the pursuit of accessible scientific software. In this work, a set of such developments are reported along with several applications. A new tomographic reconstruction algorithm, termed Generalized Fourier Iterative Reconstruction (GENFIRE), is described in detail. By combining powerful, general constraints in both real and reciprocal space, GENFIRE is shown to produce superior reconstructions compared to existing techniques and provides additional benefits including freedom from single-tilt axis restrictions, denoising through a novel Fourier technique termed resolution extension/suppression, and cross-validation through an adapted version of crystallographic $R_{free}$. In subsequent chapters, GENFIRE is applied in a diverse range of experiments including X-ray ptychographic imaging of cells, cryo-electron tomography of bacteria, correlative X-ray fluorescence imaging of algae, and scanning transmission electron microscopy (STEM) of bimetallic nanoparticles at atomic resolution. GENFIRE is fully open-source with a graphical user interface and is freely-available online. In the appendices, two additional parallel algorithms are described. The first is an optimized graphics processing unit (GPU) implementation of traditional multislice simulation for simulation of STEM image formation as well as the new Plane Wave Reciprocal-space Interpolated Scattering Matrix (PRISM) algorithm that is capable of reducing computation times of routine calculations from several weeks to a few minutes, and the second is a parallel framework for large-scale 3D phase retrieval of symmetric nanostructures from single diffraction patterns.

Book excerpt: In this dissertation, we first derive exact reconstuction algorithms for thermoacoustic tomography (TAT) and broadband diffraction tomography (a linearized inverse scattering problem) using derived time-reversal formulas. Then we focus on some important practical problems of TAT including the limited-view problem, the effects of acoustic heterogeneity, and fast reconstruction algorithms. In Chapter II, we propose time-reversal methods and apply them to tomography with diffrating sources. We first develop time-domain methods to time-reverse a transient scalar wave using only the field measured on an arbitrary closed surface enclosing the initial sources. Under certain conditions, a time-reversed field can be obtained with the delay-and-sum algorithm (backprojection to spheres) used in synthetic aperture imaging. Consequently, the physical meaning and the valid conditions of this widely used algorithm are revealed quantitatively for the first time from basic physics. Then exact reconstruction for TAT and broadband diffraction tomography is proposed by time-reversing the measured field back to the time when each source or secondary source is excited. The theoretical conclusions are supported by a numerical simulation of three-dimensional diffraction tomography. The extension of our time-reversal methods to the case using Green function in a heterogeneous medium is also discussed. In Chapter III, the limited-view problem is studied for TAT. We define a "detection region," within which all points have sufficient detection views. It is explained analytically and shown numerically that the boundaries of any object inside this region can be recovered stably. Otherwise some sharp details become blurred. One can identify in advance the parts of the boundaries that will be affected if the detection view is insufficient. Computations are conducted for both numerically simulated and experimental data. The reconstructions confirm our theoretical predictions. In Chapter IV, the effects of wavefront distortions induced by acoustic heterogeneities in breast TAT are studied. Amplitude distortions are shown to be insignificant for different scales of acoustic heterogeneities. After that we consider the effects of phase distortions (errors in time-of-flight) in our numerical studies. The numerical results on the spreads of point sources and boundaries caused by the phase distortions are in good agreement with the proposed formula. We also demonstrate that the blurring of images can be compensated for by using the distribution of acoustic velocityin the tissues in the reconstructions. In Chapter V, we discuss exact and fast Fourier-domain reconstruction algorithms for TAT in planar and circular configurations.
