To reconstruct the three-dimensional digital model of the pulmonary nodules, implement the Three-Dimensional Lung Horizon Function in the MATLAB workspace. Then open the Graphical User Interface, or GUI, to check the horizontal three-dimensional model. Drag the scroll bar on the GUI with the mouse to observe the continuous three-dimensional lung structure, allowing for the clear visualization of various types of pulmonary nodules and their relative spatial relationships with the lung tissue.
Use the Zoom function to observe the local features of the lesions and relevant three-dimensional structural output pictures. To measure the size of the nodules, use the Mark Pixel Coordinates button to calculate the distance between two points. The default color bar, jet colormap, displays values from low to high in a blue to red range.
To reset the GUI, right click the color bar and select the standard gray colormap. If the filter window is not satisfactory, use the left mouse button to adjust the window level by dragging up and down in the middle of the figure. Drag left and right to adjust the window width to display the accurate filtering range on the color bar.
The continuous three-dimensional reconstruction resulted in the axial view of the pulmonary nodules and the relationship between the nodules and the surrounding lung tissue.
