The technique was applied to CT scans ofex vivoporcine lung and to lung images of COPD patients. Results indicate that the air volume estimated using the proposed method is significantly more accurate when AVPCs are used in the air volume estimation as errors of only 1% and less than 6.7% ...
However, a considerable proportion of COPD patients are undiagnosed. An estimate of over 40% of COPD patients remain undiagnosed, particularly in developing countries [9, 10], and only 12% of individuals with chronic airflow limitations had a previous spirometry-defined COPD diagnosis during the ...

1,2,3 Young patients with SPM typically present with a history of asthma or recent inhalation of cocaine, methamphetamine, ecstasy, marijuana or hydrocarbons. 4,5,6,7 Other causes include barotrauma in asthmatics and COPD patients, rapid ascent in scuba divers, valsalva maneuvers, vomiting, ...
Table 2 Summary of stages of COPD patients in the dataset 2 Full size table Overview of the study procedure The pipeline of the proposed lobe-based method for this study is depicted in Fig.1. First, five lobes are segmented from the lung CT images by the trained Seg-Lobe model, including...
"We get high-resolution information about the lung and we can visualize how it functions," said Ouriadov, who is leading research to understand the benefits of imaging with xenon. Patients breathe in a xenon gas blend and hold their breath for 10 seconds while the MRI scanner takes its im...
In recent years, the prevention of stroke in patients with NVAF has received high attention, but the effect is not obvious. Because of the hidden nature of atrial fibrillation, real-time monitoring of patients has become a trend. With the development of big data technology, the collection of ...
The method may decompress the image by mapping the pixel value into two channels of a multi-channel output buffer, such as a red-green-blue (RGB) output buffer, such that each channel has fewer than the predefined number of bits. The method may render a scene of the image based upon ...
This means that TB can be mainstreamed as part of a holistic, CAD-assisted respiratory care package. As highlighted by accounts from Malawi, the synergies of assessing one CXR for a broad range of respiratory ailments represent a clear efficiency gain for health systems and patients, while ...
This technique will be of value in assessing the use of in vivo T1 measurement to identify abnormal pathology within the ventricular wall, particularly in patients with recent infarction. 展开全部 机器翻译 参考文献(12) 被引用(14) 社区问答 参考文献 (12) 发布时间 · 被引用数 · 默认排序 ...
