Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body. The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA Liquid-liquid extraction (LLE) is a separation technique used instead of distillation when either: (a) the relative volatilities of the compounds to be separated are very similar; (b) one or more of the mixture components are temperature sensitive even near ambient conditions; (c) the distillation would require a very low pressure or a very high distillate/feed...

Output Efficiency: Achieving Output Efficiency
0 Views •
2025
Output efficiency happens when resources are used in a way that balances what people want with how goods are produced. This means the marginal rate of substitution (MRS) matches the marginal rate of transformation (MRT). When this balance is reached, the economy makes the most of its resources without waste.Take the example of bread and milk. If consumers are happy to trade 2 loaves of bread for 1 liter of milk, the MRS is 2. But if producers only need to give up 1 loaf of bread to produce 1...

Source: Kim, D., et. al. Combined Near-infrared Fluorescent Imaging and Micro-computed Tomography for Directly Visualizing Cerebral Thromboemboli. J. Vis. Exp. (2016)This video demonstrates visualization of cerebral thrombus in mice using micro-computed tomography (micro-CT) imaging. A cerebral thrombus mouse model is injected with fibrin-targeted gold nanoparticles acting as a contrasting agent. The mouse is placed on the bed of a micro-CT machine, and images are acquired from multiple angles.

Source: Joseph C. Muskat, Vitaliy L. Rayz, and Craig J. Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana The objective of this video is to describe recent advancements of computational fluid dynamic (CFD) simulations based on patient- or animal-specific vasculature. Here, subject-based vessel segmentations were created, and, using a combination of open-source and commercial tools, a high-resolution numerical solution was determined within a flow model.
FAQs
Algorithmic complexity determines how computational demands change as genetic datasets grow, while data structures influence how information is organized and accessed. Together, these choices affect whether a workflow remains practical for sequence, variant, or genomic data. Selecting suitable structures and algorithms can reduce runtime and memory requirements without changing the intended analytical result.
Parallel processing is one of the design choices that can shorten runtimes in genetic workflows. Its relevance is greatest when analyses involve large sequence, variant, or genomic datasets, because reduced processing time can make genome assembly, alignment, variant calling, and population-scale analysis more practical. It works as part of a broader efficiency strategy that also addresses memory and processing demands.
Reducing redundant operations can lower the time and processing resources required by a genetic workflow. This principle complements choices about algorithmic complexity, data structures, and parallel processing rather than replacing them. Applying it is especially relevant when repeated work would otherwise make sequence, variant, or population-scale analyses harder to run at useful scale.
Speed alone is not sufficient for an efficient genetic workflow because the analysis must still produce accurate results. Evaluating efficiency alongside accuracy keeps resource savings from becoming the only design goal. This balance is important for genome assembly, sequence alignment, variant calling, and population-scale analysis, where practical runtimes must support scientifically reliable computational results.
A computational workflow can be reviewed by examining its data structures, algorithmic complexity, use of parallel processing, and opportunities to remove redundant operations. These choices should be judged against the need for accurate results and available time, memory, and processing resources. The outcome is a design better suited to the size and detail of the genetic dataset.
Efficiency improvements support genome assembly, sequence alignment, variant calling, and population-scale analysis by shortening runtimes and controlling infrastructure demands. They also make larger genetic studies more practical, allowing workflows to handle increasingly detailed models and datasets. The relevant benefit therefore depends on the analysis being performed and the scale of its biological data.
By controlling time, memory, and infrastructure demands, efficient workflows can make genetic analyses more reproducible and practical to repeat. This matters when studies expand in size or apply more detailed models, since resource requirements can otherwise restrict what is feasible. Efficiency therefore influences not only speed, but also the scale and repeatability of computational genetics.
