Figure 1: BAR Imaging Sequence. Each excitation pulse excites a particular shape within the field of view according to the pulse profile and the gradient strength. These n subdivisions of the image are then sequentially refocused in the same order they were excited so that each has identical T2 weighting. *n Enhanced Parallel Imaging Acceleration with a B1 Accelerated Reconstruction Sequence (B...

A new method for toroidal velocity measurements with Mach probes is presented. This technique is based on the conditional sampling technique, the triggering events being density blobs. A reconstruction of the time resolved two-dimensional profile of electron density, electron temperature, plasma potential, and toroidal velocity is possible with a single point measurement on a shot-to-shot basis.

3D iterative reconstruction of Single Photon Emission Computed Tomography (SPECT) acquisitions is a widely used but computationaly intensive process. Reconstructing data from a rotating slat collimated system increases the computation time even further. Since the sensitivity profile of such a camera is not constant over the field of view, it is important to include a system model that is as acc...

Filtered back projection (FBP) method and maximum likelihood expection maximization (OSEM) method are currently used for reconstruction of SPECT images in clinical studies. The aim of this work is to compare the image quality using different reconstruction techniques of a SPECT phantom as applied to bone scintigraphy. The resolution and contrast of the hot spheres were observed using a phantom ...

Recently the new field of parallel imaging accusation has the potential to revolutionize the field of fast MR imaging. The SPACE RIP technique is one of the parallel imaging methods which uses multiple receiver coil and utilizes the sensitivity profile information from a number of receiver coils in order to reduce the acquisition time. The image reconstruction problem of SPACE RIP is a computat...

Multiphase flow imaging is a very challenging and critical topic in industrial process tomography. In this article, simulation and experimental results of reconstructing the permittivity profile of multiphase material from data collected in electrical capacitance tomography (ECT) are presented. A multiphase narrowband level set algorithm is developed to reconstruct the interfaces between three-...

The paper builds a real-time system of 3D profile measurement using structuredlight imaging. It allows a hand-held object to rotate free in the space-time coded light field, which is projected by the projector. The surface of measured objects with projected coded light is imaged; the system shows surface reconstruction results of objects online. This feedback helps user to adjust object’s pose ...

Single molecule pulling experiments provide information about interactions in biomolecules that cannot be obtained by any other method. However, the reconstruction of the molecule's free energy profile from the experimental data is still a challenge, in particular, for the unstable barrier regions. We propose a new method for obtaining the full profile by introducing a periodic ramp and using J...

Introduction: Quantitative evaluation is recommended to improve diagnostic ability and serial assessment of dopamine transporter (DAT) density scans. We decided to compare the ordered subsets expectation-maximization (OSEM) with filtered back-projection (FBP), and to investigate the impact of different iteration and cut-off frequencies on SBR values.
