Through a CT scan, radiologists take a series of high-resolution X-ray images to get a more in-depth look inside the body. Doctors can use CT scans to find masses on the lungs or pleura, but these imaging scans cannot always determine whether the mass represents cancer or a benign (non...
Specialists must, according to law, save all X-ray images over 40years. Instead of archiving X-ray films this algorithm allows saving of wavelet coefficients vectors on magnetic or optical storage. Independent radiologists confirmed that medical data is unchanged. Secondary concern is to emphasize ...
Ray Jr Leonard. "Asbestos fiber treatment." U.S. Patent 2,940,892, issued June 14, 1960. Original Assignee Armstrong Cork. Co. Excerpts: It is the primary object of the present invention to present such an improvement. It is the further object of the present invention to present a ...
Results (TEM) The samples were analyzed with a transmission electron microscope (TEM) at approximately 20,000 X magnification. Asbestos structures are identified by a combination of morphology, quantitative elemental chemistry via Energy Dispersive X- Ray Analysis (EDXA), and Selected Area Electron Di...
Steen found that former miners in Botswana had a high prevalence of previously unrecognised pneumoconiosis due to inadequate radiographic surveillance or a failure by employers to act on X-ray results. Steen’s study was soon followed by the work of Anna Trapido at Libode in the Eastern Cape,...
In diagnostic imaging, low-dose high-resolution computed tomography of the chest (HR-TCT) is more suitable than chest X-ray examinations for assessing typical pathological processes of the lung parenchyma and pleura [4, 5]. Since 2017, low-dose HR-TCT has been established in Germany as an ...
Ajeel et al. (2021)measured the levels of asbestos fibres in the dense air sites of Baghdad (Iraq). Samples were collected using a filter, then the levels of asbestos fibres were analysed using a scanning electron microscope and an energy dispersive X-ray system. The results showed that the...
Scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) microanalysis technique has distinct advantages in providing high resolution images f... D Wang,Y Hu,R Chowdhury - Pipelines Conference 被引量: 5发表: 2011年 Examination of Asbestos Cement Pipe Deterioration with Scanning Electron...
Interstitial fibrosis on chest x-ray or CT scan. 4. Symptoms and signs of breathlessness, bibasilar inspiratory crackles, and clubbing. 5. Restrictive pattern on pulmonary function testing with reduced DLCO. 6. Exclusion of other pneumoconioses. 7. Presence of interstitial pneumonia pattern with a...
if the use of is to continue, the urgency of more effective regulations to facilitate primary prevention; 5. the usefulness of special radiology for diagnosis (45 degrees X-ray, ultrasonography, tomodensitometry). Radiophoto screening is inadequate. 展开 年份: 1982 ...
