Radiotherapy planning and attenuation correction of PET images require simulation of radiation transport. The necessary physical properties are typically derived from computed tomography (CT) images, but in some cases, including stereotactic neurosurgery and combined PET/MR imaging, only magnetic resonance (MR) images are available. With these applications in mind, we describe how a realistic, ...

Due to rising demand for traditional complementary and alternative medicine (TCAM) globally, international ministerial groups and professional bodies have been calling for a global perspective on policy and a means for countries to share information and policy initiatives with one another. The WHO Global Atlas is designed to: assess the status of development of the sector; plan for further deve...

This study aims to provide a high-resolution atlas and use it as an anatomical framework to localize the gene expression data for mouse brain on postnatal day 0 (P0). A color Nissl-stained volume with a resolution of 13.3 x 50 x 13.3 mu(3) was constructed and co-registered to a standard anatomical space defined by an averaged geometry of C57BL/6J P0 mouse brains. A 145 anatomical structures wer...

The Atlas of Descriptive Histology is an extremely comprehensive and well-organized atlas including 612 illustrations covering everything from basic tissue to full organ histology. In a clear, systematic fashion, the authors move from simple tissue structures to complex organ systems, including micrographs of the adult tongue, lip, teeth, eye, ear, and developing teeth. Each chapter is designed...

Introduction: In recent years, voxel based analysis (VBA) studies have demonstrated the potential of diffusion tensor imaging (DTI) to detect white matter (WM) damage in patients with various neurological or psychiatric disorders. In VBA, all DTI data sets are transformed to an atlas or template, whereafter the diffusion measures of control subjects and patients are evaluated in each voxel. In ...

Neonatal brain MRI segmentation is a challenging problem due to its poor image quality. Atlas-based segmentation approaches have been widely used for guiding brain tissue segmentation. Existing brain atlases are usually constructed by equally averaging pre-segmented images in a population. However, such approaches diminish local inter-subject structural variability and thus lead to lower segmen...

What is Expression Atlas? Expression Atlas [2] is an EMBL-EBI database and web-service that curates, re-analyses and displays gene expression [3] data across species and biological conditions such as different tissues, cell types, developmental stages and diseases. Expression Atlas aims to help answer questions such as 'where is my favourite gene expressed?' or 'how does its expression change i...

The current state of the art Matrix-Matrix-Multiplication (MMM) kernel is known as ATLAS, which generates the best performing MMM code by search. However, today’s computer architecture changes rapidly and it is hard to generate a high performance code without knowing how to use the new instruction sets. Since ATLAS does not make use of blocking for L2 cache, or SSE/SSE2 instruction, we are enco...
