VXLPAVisionX V4 NAME

vxlpa − computes the lung profile, and critical locations

SYNOPSIS

vxlpa if=<lungregion> of=<outfile> oh=<smoothedprof> ct=<textprofile> -w

DESCRIPTION

vxlpa takes in a separate lung and computes the lung profile based on area of the lung region across axial slices. Then using the output lung profile (ot), apex of each diaphragm is computed and the higher apex is used as top of the diaphragm.

The -w option prints characteristics of the lung profile to standard out.

CONSTRAINT

Input file if is a binary image of a single lung (left or right). Output text file ot is used to find the top of diaphragm (depreciated).

OPTIONS

	if=		left or right lung
	of=		output file
	oh=		output smoothed profile
	ot=		output text file
	-w		Provide the following charactersistics of the lung profile to standard output in wish format:
	toploc		The z coordinate of the highest point on the lungs (robust) requires min of 12
	apxloc		the z coordinate of the greates cross section area of the lung
	apxloc		the z location of the lowest point of the lung diaphragm
	tr1		the z location of the upper third of the lung by volume
	tr2		the z location of the lower third of the lung by volume
	tx		the x location of the top axis
	ty		the y location of the top axis
	ty		the z location of the top axis (4 lower than toploc)
	ax		the x location of the apex (largest area slice) axis
	ay		the y location of the apex (largest area slice) axis
	bx		the x location of the bottom projected axis
	ay		the y location of the bottom projected axis

bounding box

The lung regioun bounding box is given by xlo, xhi, ylo, yhi, zlo and zhi
