Joint CT-MRI Image Reconstruction
… imaging performance. In this work, a novel joint reconstruction framework using sparse computed tomography (CT) and magnetic resonance imaging (MRI) data is developed and evaluated. The method proposed in this study is part of the planned joint CT-MRI system which assembles CT and MRI …

Improved accuracy in susceptibility-based OEF measurements by mitigation of partial-volume effects via combined magnitude and phase reconstruction
… measurements beyond this limit by performing a joint reconstruction using both the magnitude and phase of the complex-valued MRI signal. This method is validated both in numerical simulations and on in vivo data. The ability to perform high-quality fetal brain imaging is hampered by motion of …

Reconstruction Algorithms for Novel Joint Imaging Techniques in PET
… cases in PET where the goal is to perform image reconstruction jointly on two data types.</p><p>The first case is the Beta-Gamma image reconstruction. Positron emitting isotopes, such as <sup>11</sup>C, <sup>13</sup>N, and <sup>18</sup>F, can be used to label molecules, and tracers, such as …

Image Reconstruction in Photoacoustic Computed Tomography with Acoustically Heterogeneous Media
… The majority of currently available PACT image reconstruction algorithms are based on idealized imaging models that assume a lossless and acoustically homogeneous medium. However, in many applications of PACT these assumptions are violated and the induced photoacoustic (PA) wavefields are …

Image Reconstruction of the Speed of Sound and Initial Pressure Distributions in Ultrasound Computed Tomography and Photoacoustic Computed Tomography
… to realize this promise. First, USCT image reconstruction methods based on the acoustic wave equation, known as waveform inversion methods, are computationally burdensome, limiting their widespread use. Instead, image reconstruction methods based on geometric acoustics are often employed. …
