PVE_correction_1_0_0(PETname, XY_FWHM, Z_FWHM [,atlasfile, atlaskeyfile, matrixfile, attributes])
Does PVEOut PVE correction using 4 Methods (Meltzer, Müller-Gärtner, modified Müller-Gärtner, Rousseau).
Parameters must be in string format. All input files must be in same directory as PET file. Output files
are written into PET files directory. All files are handled in Analyze7.5 format.
See user's manual for more specific information.
parameters:
PETname name of PET-file for correction
XY_FWHM trasaxial PSF FWHM used in correction
Z_FWHM axial PSF FWHM used in correction
atlasfile name of ROI map file, default:'r_volume_GMROI'
atlaskeyfile key pair values for ROI map, default:'MNI.DAT'
matrixfile MRI -> PET mapping parameter file in PET file directory default:'sn.mat'
attributes attributes.zeroCSF sets CSF voxels to zero default: 'Y'
attributes.showresults show results in matlab window default: 'N'
attributes.outlier_coeff maximum value of corrected default: '-1'
voxels will be this times
original value, if <= 1 then
no outlier cut is done
attributes.delete_addtional deletes additional output files default: 'Y'
attributes.no_M_PVC do not generate M-PVC
attributes.no_MG_PVC do not generate MG-PVC
attributes.method_flags flags for PVE correction method combinations
input files needed:
PET image declared in parameters
ROI map file declared in parameters
ROI key pair file declared in parameters
coregistration matrix file declared in parameters, which is in Matlab 6.5's format
coregistered MRI image
returns:
exit status: 0 == success, -1 == failure
output files produced:
r_volume_Meltzer M-PVC corrected PET-image
r_volume_MG MG-PVC corrected PET-image
r_volume_mMG mMG-PVC corrected PET-image
r_volume_pve.txt ASCII file containing numerical values of corrected ROIs defined in ROI key pair file
