We describe the design and operational experience of the ATLAS production system as implemented for execution on Grid3 resources. The execution environment consisted of a number of grid-based tools: Pacman for installation of VDT-based Grid3 services and ATLAS software releases, the Capone execution service built from the Chimera/Pegasus virtual data system for directed acyclic graph (DAG) gene...

by comparing the mid-sagittal section from the Paxinos atlas and corresponding DEC map from the shrinkagecorrected CT-DTI atlas. Crosshairs mark the location of the bregma. Scale is in units of mm. Fig. 1: The shrinkage-corrected CT-DTI atlas. A) Section from the population-averaged in vivo T2-w template of adult C57BL/6J brain. B) AVM map of the section in A. C) Shrinkage-distortion corrected ...

Automatic segmentation of bony structures in CT angiography datasets is an essential pre-processing step necessary for most visualization and analysis tasks. Since traditional density and gradient operators fail in non-trivial cases (or at last require extensive operator work), we propose a new method for segmentation of CTA data based on a probabilistic atlas. Storing densities and masks of pr...

An automatic method for delineating the prostate (including the seminal vesicles) in three-dimensional magnetic resonance scans is presented. The method is based on nonrigid registration of a set of prelabeled atlas images. Each atlas image is nonrigidly registered with the target patient image. Subsequently, the deformed atlas label images are fused to yield a single segmentation of the patien...

In the context of MRI-guided stereotaxy a new stereotaxic atlas of the human thalamus was developed in order to improve anatomical definition and precision in the prediction of the exact location of thalamic targets. It is based on multiarchitectonic parcellation (Nissl, myelin, calcium-binding proteins). Sagittal atlas data were digitized and registered together with 3D MRI data sets. In a coa...

An atlas of the Galactic plane (−4.7 • < b < 4.7 •) plus the molecular clouds in Orion, ρ Ophiuchus, and Taurus-Auriga has been produced at 60 and 100 µm from IRAS data. The atlas consists of resolution-enhanced coadded images having 1 ′ – 2 ′ resolution as well as coadded images at the native IRAS resolution. The IRAS Galaxy Atlas, together with the DRAO HI line / 21 cm continuum and FCRAO CO ...

In this paper a conceptual overview is given of the software foreseen to configure the ATLAS trigger system. Two functional software prototypes have been developed to configure the ATLAS Level-1 emulation and the High-Level Trigger software. Emphasis has been put so far on following a consistent approach between the two trigger systems and on addressing their requirements, taking into account t...

The creation of high-quality medical imaging reference atlas datasets with consistent dense anatomical region labels is a challenging task. Reference atlases have many uses in medical image applications and are essential components of atlas-based segmentation tools commonly used for producing personalized anatomical measurements for individual subjects. The process of manual identification of a...

A Texture Atlas is a two dimensional representation of a 3D model usable for paint systems or as a sewing pattern. The field of texture atlas generation from polygonal models has been well exploited in the recent years. The developed algorithms work on piecewise linear surface representations, but not on parametric surfaces like NURBS, that are still the main surface representation in CAD syste...

The PanDA Workload Management System is the basis for distributed production and analysis for the ATLAS experiment at the LHC. In this role, it relies on sophisticated dynamic data movement facilities developed in ATLAS. In certain scenarios, such as small research teams in ATLAS Tier-3 sites and non-ATLAS Virtual Organizations, the overhead of installation and operation of these components mak...
