COVIDCon performs even better on a larger COVID-19 CT Scan dataset that contains 82,767 images. It achieved an excellent accuracy of 99.13%, at 20,000 labels, which is 6.45% better than the next best pseudo-labeling approach. COVIDCon outperforms other state-of-the-art algorithms at ...
The CT principles can be defined in three parts: (1) X-ray projection imaging, (2) computer-assisted imaging scan and (3) image reconstruction, and are described below. Similar to planar X-ray imaging, X-ray projection in a CT scanner also uses a transmission-based technique; X-rays ...
X-rays, CT, MRI, and CT are used to diagnose lung disorders, among which X-Ray is most commonly used for the diagnosis of pneumonia. The proposed architecture will help radiologists to accurately analyze X-rays, CT, MRI, and CT, which could lead to diagnosing other respiratory diseases, ...
X-ray computed tomography (CT) is a commercially established modality for imaging large objects like passenger luggage. CT can provide the density and the effective atomic number, which is not always sufficient to identify threats like explosives and nar
Since the discovery of X-rays over a century ago the techniques applied to the engineering of X-ray sources have remained relatively unchanged. From the inception of thermionic electron sources, which, due to simplicity of fabrication, remain central to

It correlates well with the porosity profile (Fig. 3), but it is more likely an image subtraction artifact that would occur if a CT scan has been taken too close to the end of the core. 6. Conclusions Tight chalk samples, which originate from oil reservoirs located in the Danish sector...
Also a smart design of experiments and measurement conditions may help to increase the applicability of CT for time-lapse experiments. This could be to first do a high-resolution scan of the structure, which typically is time consuming and then do quick low-resolution scans to monitor only the...
