nipype.interfaces.petpvc module¶
PETPVC is a toolbox for partial volume correction in positron emission tomography.
PETPVC¶
Bases: CommandLine
Wrapped executable:
petpvc
.Use PETPVC for partial volume correction of PET images.
PETPVC (1, 2) is a software from the Nuclear Medicine Department of the UCL University Hospital, London, UK.
Examples
>>> from ..testing import example_data >>> #TODO get data for PETPVC >>> pvc = PETPVC() >>> pvc.inputs.in_file = 'pet.nii.gz' >>> pvc.inputs.mask_file = 'tissues.nii.gz' >>> pvc.inputs.out_file = 'pet_pvc_rbv.nii.gz' >>> pvc.inputs.pvc = 'RBV' >>> pvc.inputs.fwhm_x = 2.0 >>> pvc.inputs.fwhm_y = 2.0 >>> pvc.inputs.fwhm_z = 2.0 >>> outs = pvc.run()References
