Artifact definition3/24/2023 Note: When no URI is specified, the system defines a unique value internally leaving URI fields blank does not make them equivalent. Conversely, if one project area used a different URI or no URI at all, the system would consider the Business Requirement type in that project area to be a different resource type. So for example, if you have Business Requirement artifacts in different project areas and they all use the same URI for that artifact type, the system considers those types to be the same – even if the project areas use different labels to describe the type (which is not recommended – ideally labels should be consistent too). Two resources that have the same URI are considered to be the same. In this case, the “resources” in question are the artifact types, attributes, enumerations, relationships, and so on that describe your type system. In fact, a URL (like the address of this web page) is a type of URI. What is a URI anyways?Ī “uniform resource identifier” (URI) identifies a particular resource unambiguously. In this article, we explore in more depth what it means to define URIs, what a URI consists of, and best practices in defining your own URI vocabularies, expanding upon the OASIS Open Services for Lifecycle Collaboration (OSLC) guidelines. This becomes even more important when you use Lifecycle Query Engine (LQE) for reporting, and especially for applications like IBM DOORS Next Generation (DOORS Next) where types can vary greatly across project areas and configurations. In many articles and best practice guidelines for IBM Engineering Lifecycle Management (ELM), we recommend defining URIs for artifact types, attributes, enumeration values, and so on. 2-hydroxyglutarate peak: resonates at 2.Defining URIs for artifact types, attributes, and other resourcesīuild basis: IBM Engineering Lifecycle Management 6.x, 7.x.arterial spin labeling (ASL) MR perfusion.dynamic contrast enhanced (DCE) MR perfusion.dynamic susceptibility contrast (DSC) MR perfusion.metal artifact reduction sequence (MARS).turbo inversion recovery magnitude (TIRM).fluid attenuation inversion recovery (FLAIR).diffusion tensor imaging and fiber tractography.MRI pulse sequences ( basics | abbreviations | parameters). ![]() iodinated contrast-induced thyrotoxicosis.iodinated contrast media adverse reactions.clinical applications of dual-energy CT.as low as reasonably achievable (ALARA).faint grid lines present on an image, with no grid cut off.loss of contrast in areas of different pixel density yet not change in density can be seen i.e.tighter digital collimation in conjunction with reprocessing will correctly assign the correct values of interest.this is often due to a largely collimated area of smaller anatomy i.e.image appears washed out and underexposed.often a computer error often fixed with recollimation post exam (this should be explored before re-examination).the digital image often will have obscurely shaped, tight collimation that defies logic.similar to ghosting, however, the digital detector not being calibrated when promoted is the cause.failure of detector offset correction 4.this artifact should be carefully examined, if it does not interfere with the anatomy, it is not a detector failure/grid cut off, rather a limitation of the detector calibration.faint radiopaque striping (often vertical) in the background of an image, yet not evident on the anatomy.large areas of signal loss, due to detector drop.occur when two separate DR/CR (digital/computed radiography) images are merged into a single image (see case 3).increased radiation exposure required for portable DR (digital radiography) examinations.electronics are visible on the exposed image.latent image from previous exposure present on current exposure.fixer splashed on film prior to developing.air bubbles sticking to film during processing.black “lightning” marks resulting from films forcibly unwrapped or excessive flexing of the film.malfunction of the machine or placing the film in the fixer before developer solution. ![]()
