NAME

vaorta − finds a seed point inside the aortic lumen at carina level

SYNOPSIS

vaorta if=<chestmap> iv=<vertebraemap> il=<lungmap> cy=<carinay> cz=<carinaz> -w -v

DESCRIPTION

vaorta vaorta finds a seed point inside the aortic lumen at carina level from a map image by fitting the largest circle into the unlabeled region close to veterbra and lung. The input is a chest map (lungs, airway, fat, bone), a binary vertebrae map, a binary lung map and the y, z coordinates of the carina computed by vcarina. The output is the x, y coordinates of the seed point and the estimated radius (pixel) of the largest circle.

Input file if is a standard chest map image(VXB). Input file iv is a binary vertebrae map. Input file il is a binary lung map.
