- Abstract: The lung airway tree modeling is essential to work for the diagnosis of
pulmonary diseases, especially for X-Ray computed tomography (CT). The airway
tree modeling on CT images can provide the experts with 3-dimension
measurements like wall thickness, etc. This information can tremendously aid
the diagnosis of pulmonary diseases like chronic obstructive pulmonary disease
[1-4]. Many scholars have attempted various ways to model the lung airway tree,
which can be split into two major categories based on its nature. Namely, the
model-based approach and the deep learning approach. The performance of a
typical model-based approach usually depends on the manual tuning of the model
parameter, which can be its advantages and disadvantages. The advantage is its
don't require a large amount of training data which can be beneficial for a
small dataset like medical imaging. On the other hand, the performance of
model-based may be a misconcep-tion [5,6].
In recent years, deep learning has achieved good results in the field of
medical image processing, and many scholars have used UNet-based methods in
medical image segmentation [7-11]. Among all the variation of UNet, the UNet 3+
[11] have relatively good result compare to the rest of the variation of UNet.
Therefor to further improve the accuracy of lung airway tree modeling, this
study combines the Frangi filter [5] with UNet 3+ [11] to develop a
dual-channel 3D UNet 3+. The Frangi filter is used to extracting vessel-like
feature. The vessel-like feature then used as input to guide the dual-channel
UNet 3+ training and testing procedures.

Lung ultrasound is a growing modality in clinics for diagnosing acute and chronic lung diseases.
It is complicated by complex reverberations from the pleural interface caused by the inability of ultrasound to penetrate air.
We propose LUNA, an AI model that directly reconstructs lung aeration maps from RF data.
