Susceptibility artifact from platinum coil packs impairs the visibility of perianeurysmal soft tissues at conventional 3D time-of-flight MR angiography. These artifacts limit the evaluation for residual-recurrent aneurysm and parent vessel stenosis. Reducing the echo time can decrease the artifact and improve perianeurysmal visualization. The purpose of this study was to assess quantitatively t...

This poster summary describes research that investigates the use of mobile technologies to support young children’s collaborative artifact creation in outdoor environments. Collaboration while creating a knowledge artifact is an important part of children’s learning. Key aspects of supporting this process outdoors are discussed. An approach is outlined that uses mobile computers for artifact cr...

Different programming languages can be involved in the implementation of a single software application. In these software applications, source code of one programming language interacts with code of a different language. By refactoring an artifact of one programming language, the interaction of this artifact with an artifact written in another programming language may break. We present a study ...

The diffusion weighted images acquired with the multiband sequence or the Lifespan protocols shows a type of slice distortion artifact. We find that this artifact is caused by the eddy currents, which can be induced by the diffusion gradient associated with either current DW image or the previous DW images. The artifact can be corrected by further tuning the compensation circuit in the MR hardw...

This artifact is intended to demonstrate the module system of the Wyvern programming language and consists of a Linux virtual machine with a snapshot of the Wyvern programming language’s codebase. The Wyvern codebase contains a test suite that corresponds to the code examples in the paper accompanying the artifact. In addition, the artifact contains a document describing how to compile and run ...

Benchmarking of information security policies has two challenges: lack of communication between organizations and no two organizations are identical. In this paper, we attempt to propose an artifact for a benchmarking method of information security policy (BMISP), which can resolve the above challenges. We employ design science methodology, activity theory and international standards to design ...

In most cases, people judge creativity by evaluating the resulting artifact, after the productive behavior has been completed. Hence, we will concentrate on the artifact here. However, sometimes the artistic process is inferable by the evaluator, perhaps due to some attributes of the artifact, or sometimes it’s even observable. Colton (2008) argues that art is identified as more creative if the...

Artifacts and image quality are two sides of the same coin. The ring artifact is scanner-based and caused mainly by either a miscalibrated element or a defective element of a detector row. We describe a rare cause of the ring artifact that appeared on a transaxial CT image because of a loose electronic contact. To our knowledge, this particular cause of the ring artifact has not been described ...

The purpose of this study was to evaluate the presence of chemical-shift artifacts on cranial MR and to illustrate the interrelationship among chemical-shift artifacts, variable acquisition parameters, and field strength. Measurements of chemical-shift artifacts were performed on scans obtained from a volunteer imaged in a 1.5-T General Electric system at bandwidths of 8, 16, and 32 kHz, using ...
