A CT scan provides detailed images of the lungs, allowing healthcare providers to assess the extent of lung damage and identify any abnormalities. This imaging technique can help confirm a diagnosis of COPD and guide treatment decisions. CT扫描是COPD最常见的诊断试验之一。CT扫描提供了肺部详细的影像...
A low-dose CT scan is a noninvasive medical test that uses specialised technology that continuously rotates in a spiral motion to take multiple three-dimensional X-ray images, producing detailed images of the inside of the lungs. These highly detailed images can reveal early-stage lung nodules ...

For this reason, this knowledge can be applied to lung lobe segmentation and lesion segmentation in CT scan images. In this study, deep learning semantic segmentation was used for the lung severity scoring of the COVID-19 infection. The proposed method utilized a combination of 3D-UNet models ...

(the time period from needle insertion to the completion of the final CT scan after biopsy), the operator experience, the number of pleural punctures and needle redirections, the interlobar fissure puncture, the patient puncture position (supine, prone, or others), the pulmonary hemorrhage along...
"n"nResults: With the proposed method, the lungs parenchymal elasticity and air-trapping were determined quantitatively. The more this feature tended to zero, the more severe air-trapping and obstructive pulmonary disease is. By analyzing CT images in the healthy and patient groups, we calculated...
With these scan-specific statistics, we can then considerably enhance the parenchyma lesions compared with the lung window (see Methods), which thus makes the previous visually indiscernible lesions visible. Third, discovery and quantification of novel subvisual lesions. During the discovery of the ...
Artificial intelligence processing of CT. A Research workflow. B-D The original CT scan of the lung, Deep learning convolutional neural network was used to remove pulmonary vessels and mask images after segmentation. E The two dimensional mask sequence is combined into a three dimensional mask sequ...
ventilation measurement has become increasingly utilized in radiation oncology for functional avoidance radiotherapy, where the radiation plan is designed to avoid the most functional portions of the lungs because its damage can cause the most significant functional decrease [29,30]. The next step is ...
