Abstract:
Chest imaging is an important tool in managing critically ill patients. Basic chest radiology is still used to quickly detect abnormalities in the chest. Critical care nurses are often the ones who first read the radiologist’s report of chest radiograph results and provide their interpretation to a physician. Oftentimes, chest radiographs are obtained routinely on a daily basis for every critical care patient, with the goal of effective clinical management. Critical care nurses can confirm cardiopulmonary assessment findings by also evaluating their patient’s chest radiographs and reviewing the radiologist’s report. By learning some basic skills in interpreting and evaluating chest radiographs, nurses can recognize and localize gross pathologic changes visible on a chest radiograph. This article provides basic chest radiograph interpretation information that allows readers to review relevant anatomy and physiology, summarize normal and abnormal findings on chest radiographs, and describe radiographic findings in common pulmonary and cardiac disorders.

Abstract:
Chest radiographs (CXR) are the most performed imaging tests and rank high among the radiographic exams with suboptimal quality and high rejection rates. Suboptimal CXRs can cause delays in patient care and pitfalls in radiographic interpretation, given their ubiquitous use in the diagnosis and management of acute and chronic ailments. Suboptimal CXRs can also compound and lead to high inter-radiologist variations in CXR interpretation. While advances in radiography with transitions to computerized and digital radiography have reduced the prevalence of suboptimal exams, the problem persists. Advances in machine learning and artificial intelligence (AI), particularly in the radiographic acquisition, triage, and interpretation of CXRs, could offer a plausible solution for suboptimal CXRs. We review the literature on suboptimal CXRs and the potential use of AI to help reduce the prevalence of suboptimal CXRs.

Abstract:
Organ procurement coordinators often provide independent interpretations of chest radiographs during donor care. Catheter or tube position, lobar atelectasis, extra-alveolar air, air bronchograms, pleural fluid, and other findings are important throughout donor care and when deciding if a lung is acceptable for transplantation. Technical factors, features of a normal chest radiograph, and abnormal radiographic findings are reviewed and examples are presented.

Abstract:
Navicular syndrome (navicular disease) plays a major role in the equine industry as a chronic, degenerative, and often career-limiting disease process, affecting a variety of breeds of horses. In addition to clinical signs and diagnostic analgesia, diagnostic imaging plays a key role in the identification of this disease process; radiography is the most widely used imaging modality. In addition to their clinical utility, foot radiographs are a standard element of most pre-purchase examinations. Good radiographic quality and positioning are necessary for accurate interpretation. Radiographic lesions of the navicular bone, such as sclerosis, enlarged synovial invaginations, distal border fragments and flexor cortical erosions, are important to identify and understand because of their potential role in the disease process. This article reviews an approach to radiological evaluation and interpretation of lesions affecting the navicular bone.

Abstract:
Large, labeled datasets have driven deep learning methods to achieve expert-level performance on a variety of medical imaging tasks. We present CheXpert, a large dataset that contains 224,316 chest radiographs of 65,240 patients. We design a labeler to automatically detect the presence of 14 observations in radiology reports, capturing uncertainties inherent in radiograph interpretation. We investigate different approaches to using the uncertainty labels for training convolutional neural networks that output the probability of these observations given the available frontal and lateral radiographs. On a validation set of 200 chest radiographic studies which were manually annotated by 3 board-certified radiologists, we find that different uncertainty approaches are useful for different pathologies. We then evaluate our best model on a test set composed of 500 chest radiographic studies annotated by a consensus of 5 board-certified radiologists, and compare the performance of our model to that of 3 additional radiologists in the detection of 5 selected pathologies. On Cardiomegaly, Edema, and Pleural Effusion, the model ROC and PR curves lie above all 3 radiologist operating points. We release the dataset to the public as a standard benchmark to evaluate performance of chest radiograph interpretation models.

Abstract:
Radiographer image interpretation processes at a tertiary paediatric hospital are undergoing a review. This study explored which barriers and positive outcomes radiographers of this facility identified with, in relation to radiographer abnormality detection systems from the literature. Consistent participation was reported as the barrier most associated with, while self- assessment was deemed the outstanding benefit for radiographers practising a formal radiographer image interpretation system. Associated benefits to self-assessment included improved image interpretation, improved radiographic positioning, and improved image quality stemming from self-assessment.

Abstract:
Archaeologists and conservators have different problems in inspecting metal-type pieces extracted from the archaeological sites, such as their large number and the complexity of the materials and their shapes. Usually, all of the pieces are hidden under the oxidation layers. From this point of view, a non-destructive analysis technique such as digital radiography imaging can detect and discriminate one piece from another. Also, the shape of pieces, state of the metal core, and assessment of its handling can be investigated. But there are still some problems with metal-type parts with a certain thickness. The generated X-ray image can be very foggy and without adequate quality. This will prevent the method to discriminate small details about the shape, hidden structures, and the real level of oxidation, and the presence of cracks. A solution for improving the quality of the x-ray image can be implementing a digital imaging processing algorithm for enhancing the quality of the radiographs. In this study, the metal parts are carried out from two important Iberian-Roman sites located on the coast of the municipality of Burriana (Castellón), i.e. Sant Gregori and Torre d'Onda. This set of pieces belong to the archaeological museum of Burriana, Spain, and are investigated by X-ray imaging. This study has used the “Fast 2D Gaussian convolution first-order infinite impulsive response” (IIR) to extract the maximum detail for better interpretation of the image. A multidisciplinary perspective has been desired for this study.

Abstract:
During in-service inspections, experts are faced with the delicate task of establishing a complete diagnosis of defects from radiographs. Should a defect be detected, one must be able to demonstrate that the component still meets regulatory requirements. Thus, it is essential to be able to characterize precisely the defect, especially when the demonstration relies on mechanical calculus. However the characterization of the defect by only g or X-ray is sometimes very difficult, and the justification process can thus be jeopardized. In such cases, signal processing can be very helpful for the interpretation of the data and for the characterization (positioning and sizing) of the defect. This paper presents a 3-D reconstruction processing in hard conditions representatives of pipe inspections: the incidence angle is very reduced and thus the radiographs contain very little information along the vertical direction. The reconstruction process relies on the estimation of the attenuation. It is called inversion because it restores the attenuation from both data and prior information. The method has been tested on radiographs of a block with real defects and the performances were evaluated from a mock-up with several electro-drilled cylindrical defects. Even in the case of limited incidence, the method provides very useful 3D results. Moreover this process can be applied whatever the nature of the source. When a larger source is used in order to inspect thick components, signal processing allows to reduce the inevitable blur which leads to improved accuracy. In conclusion, signal processing and especially 3D reconstruction in the case of radiography can turn out to be a key step fur in-service inspection of major NPP components.

Abstract:
Abstract This paper addresses the analysis of die attach disbonds (delaminations) of silicon die in a multichip module (MCM). A silicon die attached to a silicon substrate in an MCM requires good adhesion for thermal dissipation and reliability purposes. Traditionally, die attach is evaluated by destructively measuring adhesion or non-destructively measuring voiding through x-ray radiography. For this paper, non-destructive acoustic microscopy and destructive dye penetrant testing were used to supplement the x-ray radiography. A sample in which x-ray radiography showed little die attach voiding had significant die attach disbonds at both the die/die attach interface as well as the die attach/substrate interface. The disbonds were identified by the acoustic microscope. Interpretation of the acoustic microscopy data proved complex and required careful comparison of the C-mode images generated with the A-scans at specific locations. The nature of the disbonds at the A-scan locations was confirmed using dye penetrant testing, metallurgical cross section and optical microscopy. The disbonded areas can change the thermal dissipation characteristics and mechanical stress distribution of the sample and indicate processing problems. X-ray radiography is effective for determining density variations or voiding in the die attach and acoustic microscopy is effective for determining interface characteristics and the combination of the two techniques provides an excellent approach for evaluating die attach in MCM’s. These techniques can be applied to interfacial analysis of other structures and can be used to characterize interfaces for modeling and establish evaluation criteria for non-destructive process monitoring.

Abstract:
The thicknesses of 384 rhythmic couplets were measured along a composite sequence of glacial Lake Ojibway glaciolacustrine deposits recovered in two sediment cores from Frederick House Lake, Ontario. The visual comparison of distinctive couplets in the CT-scan radiographs of the Frederick House core samples to photographs of core samples from Reid Lake show a match of ±1 varve number from v1656-v1902, and ±5 varve numbers between v1903-v2010, relative to the regional numbering of the Timiskaming varve series. There are two interpretations for the post-v2010 couplets that fall within the Connaught varve sequence of the regional series. In the first, the interpreted numbering spans from v2066-v2115, which produces a gap of 55 missing varves equivalent to v2011-v2065, and corresponds to the original interpretation of the Connaught varve numbering. The second spans v2011a-v2060a, and represents alternative (a) numbering for the same varves. Varve thickness data are listed in spreadsheet files (.xlsx and .csv formats), and CT-Scan radiograph images of core samples are laid out on a mosaic poster showing the interpreted varve numbering and between-core sample correlations of the varve couplets.
