DRO Descriptions
Amyloid DRO Volumes (30 volumes) (BETA)
The PET/CT Digital Reference Objects (DROs) are synthetically generated DICOM
image files of known voxel values for positron emission tomography (PET) and x-ray
computed tomography (CT).
The
University of Washington Imaging Research Laboratory currently offers five PET and PET/CT Digital Reference Objects:
DRO for SUV Computation
The DRO for calculation of PET SUV values can be found
here
DROe for SUVpeak, Fusion Alignment, and ROI Fidelity
The DROe for testing SUVpeak calculations, PET/CT fusion alignment, and ROI fidelity can be found
here
DROmtv for Metabolic Tumor Volume Computation
The DROmtv for calculation of PET Metabolic Tumor Volume can be found
here.
A noisy version of the DROmtv is also available.
DRObrain for Differential Amyloid Uptake
The DROmtv for calculation of PET Metabolic Tumor Volume can be found
here.
Hoffman Brain Phantom DRO
A digital version of the ubiquitous Hoffman Phantom can be found
here.
The PET/CT DROs are supported by the
Quantitative Imaging Biomarker Alliance (QIBA).
The primary goals and objectives of the PET/CT Digital Reference Objects are to support the
QIBA FDG-PET
'Technical Validation' efforts for profile development by
providing common reference standards that can be adopted and modified by PET/CT scanner and display
station manufacturers.
