NAME
vhtop − estimates the endpoints of pulmonary vessel above heart.
SYNOPSISvhtop if=<infile> xs=<xres> ys=<yres> zs=<zres> of=<outfile>
DESCRIPTIONvhtop takes in the sagittal map with segmented organs such as airway, lungs, fat as well as aorta. Then it searches for the first slice that descending aorta appears and the last slice that ascending aorta appears. These two slices should also contain airway and should be close enough to the center of the image. Then in these two slices a largest circle-fitting is performed in the space adjacent to the airway. The center of the largest circle is considered as the estimated center of the end of pulmonary vessel and the radius is the estimated radius.
CONSTRAINTInput file if is the sagittal map containing segmented airway, lungs, fat and aorta. xs,ys,zs are the xres, yres and zres in the sagittal view. Output file of is the sagittal map with the estimated circles. It also prints out the x,y,z coordinates of the largest circle centers and the corresponding radius.
