Repeat Analysis Program As A Quality Assurance System For Radiology Management: Causal Repeat and Challenges [PDF]

open access: yesE3S Web of Conferences, 2023
Rejected or repeated images analysis remains a significant challenge, particularly in digital imaging. Despite the expectation that the transition from conventional to digital systems would reduce repetition rates, the reality is that repetition rates ...

On The Application Of Log Compression and Enhanced Denoising In Contrast Enhancement Of Digital Radiography Images [PDF]

open access: yesarXiv, 2023
Digital radiography (DR) is becoming popular for the point of care imaging in the recent past. To reduce the radiation exposure, controlled radiation based on as low as reasonably achievable (ALARA) principle is employed and this results in low contrast images.

Two-phase argon and xenon avalanche detectors based on Gas Electron Multipliers [PDF]

open access: yesNucl.Instrum.Meth. A556 (2006) 273-280, 2005
We study the performance of two-phase avalanche detectors based on Gas Electron Multipliers (GEMs) and operated in an electron-avalanching mode in Ar and Xe. Emission, gain, energy resolution and stability characteristics of the detectors were studied.

Autogenous self‐healing of concrete: Experimental design and test methodsA review

open access: yesEngineering Reports, Volume 5, Issue 1, January 2023., 2023
Concrete exhibits an intrinsic ability to heal cracks, defined as “autogenous self‐healing.” However, despite code restrictions, autogenous self‐healing of concrete shows limited effectiveness in practice. This indicates the need for further research to provide engineers with reliable design rules.

Digital Radiography Corrosion Mapping on Gas Pipelines

open access: yesCommunications, 2017
Digital radiography (DR) is a powerful technique that can be used in non-destructive testing for identification of internal or external defects and corrosion mapping. New generation of digital flat panel detectors become more and more competitive to film

Deglaciation history and subsequent lake dynamics in the Siljan region, south‐central Sweden, based on new LiDAR evidence and sediment records

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3515-3545, December 2022., 2022
Glacial geomorphology and postglacial landforms, derived from LiDAR‐based digital terrain models, together with radiocarbon‐dated sediment sequences, form the basis for landscape reconstruction spanning c. 2000 years (10,500–8500 cal. bp). After formation of streamlined terrain and ribbed moraine tracts followed intense glaciofluvial activity at ...

Digital radiography of the chest

open access: yesSeminars in Roentgenology, 1997
Digital radiography is an appropriate method for both bedside and in-department chest radiographs. Its major advantage in bedside chest radiography is its control of the displayed optical density of these radiographs. With dynamic range control processing, it improves the visibility of tubes and lines superimposed on the mediastinal tissues.
