NAME¶
volume_reconstruction - Volume reconstruction
SYNOPSIS¶
volume_reconstruction [options] refImage xform0 inImage0 [xform1 inImage1 ...]
DESCRIPTION¶
Iterative volume reconstruction from co-registered images using inverse
interpolation or joint deblurring
OPTIONS¶
- --help
- Write list of basic command line options to standard output.
- --help-all
- Write complete list of basic and advanced command line options to standard
output.
- --wiki
- Write list of command line options to standard output in MediaWiki
markup.
- --man
- Write man page source in 'nroff' markup to standard output.
- --version
- Write toolkit version to standard output.
- --echo
- Write the current command line to standard output.
- --verbose-level <integer>
- Set verbosity level.
- --verbose, -v
- Increment verbosity level by 1 (deprecated; supported for backward
compatibility).
- --threads <integer>
- Set maximum number of parallel threads (for POSIX threads and
OpenMP).
- --exclude-first-image, -x
- Exclude first image from reconstruction as a separate registration target
image)
- --crop <string>
- Crop reference to pixel region x0,y0,z1:x1,y1,z1
- --pass-weight <string>, -W
<string>
- Set contribution weight for a pass in the form 'pass:weight'
Reconstruction Grid¶
- --recon-grid <string>
- Define reconstruction grid as Nx,Ny,Nz:dX,dY,dZ[:Ox,Oy,Oz]
(dims:pixel:offset)
- --recon-grid-path <string>, -R
<string>
- Give path to grid that defines reconstructed image grid [including offset]
[Default: NONE]
Initial Volume Injection Parameters¶
- --isotropic-injection
- Use isotropic volume injection [otherwise: scaled with pass image pixel
size per dimension]
- --injection-kernel-sigma <double>, -S
<double>
- Standard deviation of Gaussian kernel for volume injection in multiples of
pixel size in each direction. [Default: 1]
- --injection-kernel-radius <double>, -r
<double>
- Truncation radius factor of injection kernel. The kernel is truncated at
sigma*radius, where sigma is the kernel standard deviation. [Default:
2]
Volume Reconstruction Options¶
- --inverse-interpolation-kernel
- Kernel for the inverse interpolation reconstruction Supported values:
"cubic", "linear", "hamming-sinc",
"cosine-sinc", where the default is "cubic", or use
one of the following:
- --cubic, -C
- Tricubic interpolation [This is the default]
- --linear, -L
- Trilinear interpolation (faster but less accurate)
- --hamming-sinc, -H
- Hamming-windowed sinc interpolation
- --cosine-sinc, -O
- Cosine-windowed sinc interpolation (most accurate but slowest)
- --deblurring
- Kernel shape to approximate the point spread function for joint deblurring
reconstruction (selecting one of these disables inverse interpolation
reconstruction) Supported values: "box", "gaussian",
or use one of the following:
- --box
- Box-shaped kernel
- --gaussian
- Gaussian kernel
- --psf <string>
- Explicitly set point spread function size as x,y,z. Use with 'deblurring'
kernel reconstrunction.
- --psf-scale <double>
- Scale point spread function size by this value. Use with 'deblurring'
kernel reconstrunction. [Default: 1]
Optimization Parameters¶
- --num-iterations <integer>, -n
<integer>
- Maximum number of inverse interpolation iterations [Default:
20]
- --fourth-order-error, -f
- Use fourth-order (rather than second-order) error for optimization.
Regularization Parameters¶
- --l-norm-weight <double>
- Set constraint weight for Tikhonov-type L-Norm regularization (0 disables
constraint) [Default: 0]
- --no-truncation, -T
- Turn off non-linear regional intensity truncation
Output Options¶
- --output <string>, -o
<string>
- Output path for final reconstructed image [Default: reconstructed.nii
]
- --write-injected-image <string>
- Write initial volume-injected image to this path [Default:
NONE]
- --write-lowest-max-error-image <string>
- Optional path to write reconstructed image with lowest MAXIMUM error.
[Default: NONE]
- --write-images-as-float, -F
- Write output images as floating point
