Digital Reference ObjectDone1. Collected PET/CT images of the same reference

phantom from scanners from GE, Philips, Siemens

2. Image data collated and compared w.r.t. DICOM header information

3. Contacted Mfrs to start discussion ofo DICOM information neededo Acceptable processo Not complete response yet

Not meant as a "Consumer's Report" evaluation, but rather to facilitate multi-center comparisons

Digital Reference Object• Sample Image Sections from Six Different Scanners

Digital Reference ObjectPopulated DICOM fields by manufacturer

QuickTime™ and a decompressor

are needed to see this picture.

Digital Reference ObjectNext Steps:• Initiate manufacturer-driven discussion on methods

for distributing and testing a purely digital version of the reference phantom

• Test digital reference object on 3rd party review stations

• Initiate IHE process for manufacturer-driven roll-out• Explore potential for moving further up the data

generation stream, i.e., closer to raw data
