the device definitions are simple text files, so if you knowexactlywhat you need to spoof, you can just edit them by hand. Note that all the devices in the above mentioned list were submitted by users, so if you haven't found the device you wanted, you are out of luck. I cannot cr...
Although some are made from simple metals, combinations of metals — called alloys — produce magnets of different strengths. For example: Ferrites or ceramic magnets: These are like those used in refrigerator magnets and elementary-school science experiments. They contain iron oxide and other ...
A simple and inexpensive breast phantom is described for use in magnetic resonance imaging. The work demonstrates the similarity of the phantom materials to in vivo breast tissue in terms of T1 relaxation times. The phantom is also qualitatively compared with images acquired from a patient with ...
I for benign and Types II and III for malignant achieved a 91% sensitivity and 83% specificity in diagnosing breast cancer.33However, because qualitative assessment is inherently subjective, it has limitations in terms of repeatability and applicability in both diagnostic setting and inclinical trials...
In simple terms, when the sampling ratio exceeded the desired sparsity, the penalty should be increased, and vice versa, and the number of points 𝑆𝑃𝑟𝑒𝑖,𝑗Si,jPre should be guaranteed in the end to be equivalent to the desired number of samples. In forward propagation, ...
MRI had higher inter-observer agreement values than CT in terms of the pleural asbestos-related pathologies’ assessment [91]. In 1995 the International Mesothelioma Interest Group (IMIG) and the International Association for the Study of Lung Cancer (IASCL) proposed an international MPM TNM ...
