Hybrid scanners such as PET/CT have in the past emerged as a valuable modality in clinical routine as well as an important research tool. Recently, the newly developed fully integrated PET/MR scanners were introduced to the market, raising high expectations especially due to the excellent soft tissue contrast and functional imaging capabilities of MRI. In this issue of the American Journal of N...

Protein-protein interactions control essential steps in signal transduction pathways and other intracellular processes, and assembly of protein complexes modulates and responds to the regulatory events that exist in living animals. We have used microPET and fluorescence imaging to detect interactions between p53 tumor suppressor and large T antigen (TAg) of SV40 virus in a tetracycline-inducibl...

Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...

One-third of the people with an age over twenty have some signs of degenerated discs. However, in most of the patients the mere presence of degenerative discs is not a problem leading to pain, neurological compression, or other symptoms. This paper presents an interval type-2 fuzzy hybrid rule-based system to diagnose the abnormal degenerated discs where pain variables are represented by interv...

Introduction: As the number and complexity of partially sampled dynamic imaging methods continues to increase, understanding how these methods relate and perform becomes increasingly difficult. Modulation transfer functions (MTF) have been used extensively in medical imaging in general, and X-ray imaging in particular, to evaluate the performance of imaging systems. An MTF graphically displays ...

Abstract Lucky imaging is a high-resolution astronomical image recovery technique with two classic implementation algorithms, i.e. selecting, shifting and adding in space, data selecting synthesizing Fourier space. This paper proposes novel lucky algorithm where space-domain frequency-domain selection rates as link, the algorithms are combined successfully, making each proper subset of hybrid a...
