For this example, the target label regions are the lungs, liver, kidneys, and spleen. To start, select the segmentation model, which includes labels for all of the target regions. Perform Label Mapping After you select a model for the first time in a labeling session, the Label Mapping dia...
First, lungs are automatically segmented to locate the mediastinum region. Shape features by Hessian analysis, local scale, and circular transformation are computed at each voxel. Spatial prior distribution is determined based on the identification of multiple anatomical structures (esophagus, aortic arch...
It has been recognized for a century that biological specimens can be made optically transparent by methods that reduce internal differences in refractive index within the tissue to reduce scatter, thus enabling visualization of deep structures (Spalteholz, 1914). Recently, there has been a resurgence...
In recent years, Shanghai has continuously strengthened the atmospheric environmental protection and governance, and the ambient air quality of the city has been gradually improved, but there is still a big gap between the concentration of atmospheric pollutants such as PM2.5[1], nitrogen oxide [2...
e.g. composing an X-ray image of the thorax by left and right lung structures as well as the heart, which are all anatomically constrained by each other in their relative locations. Secondly, CNNs max-pooling operation additionally leads not only to a loss of fine spatial information, but...
From the slice-based analysis, a bounding box around the structures of interest can be computed. The system uses 6 convolutional, 4 pooling and one fully connected layer and uses 333 scans for training and 110 for validation. The test set contains 110 scans. The average Dice score of...
Mycotoxins are secondary metabolites mainly produced by various mycelial structures of filamentous fungi growing on a wide range of agricultural commodities. The term "myco" in mycotoxin originates from the Greek word "mykes", which refers to fungus [2]. Some fungi are capable of producing more ...
Integrins have high expression in lungs and other vital organs whereas ACE2 is found to have negligible occurrence in the lungs [274]. Expression of integrins is high in lung cells (especially αVβ6, αVβ8, α5β1) and the ICAM-1. Thus, the high infectivity of the virus may be ...
