phm2pj — calculate projections through a phantom object.

SYNOPSIS¶

DESCRIPTION¶

phm2pj calculates projections through a phantom object, either a predefined --phantom or a --phmfile.

Every tool is run through ctsim-nogui, as in "ctsim-nogui phm2pj ...", or directly if a symbolic link of that name points at it.

The arguments and options are as follows:

outfile

Name of output file for projections

ndet

Number of detectors

nview

Number of rotated views

--phantom

Phantom to use for projection

herman

Herman head phantom

shepp-logan

Shepp-Logan head phantom

unit-pulse

Unit pulse phantom

--phmfile

Get Phantom from phantom file

--desc

Description to store in the projection file

--nray

Number of rays per detector (default = 1)

--rotangle

Angle to rotate view through (fraction of a circle)

--geometry

Geometry of scanning

parallel

Parallel scan beams (default)

equilinear

Equilinear divergent scan beams

equiangular

Equiangular divergent scan beams

--focal-length

Focal length ratio (ratio to radius of view area)

--center-detector-length

Distance from center of phantom to detector array

--view-ratio

Length to view (view diameter to phantom diameter)

--scan-ratio

Length to scan (scan diameter to view diameter)

--offsetview

Initial gantry offset in 'views' (default = 0)

--trace

Trace level to use

none

No tracing (default)

console

Trace text level

--verbose

Report progress and details while running.
