Digital Reference Object Done 1.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 of oDICOM information needed oAcceptable process oNot 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 Object Populated DICOM fields by manufacturer Digital Reference Object Next Steps: Initiate manufacturer-driven discussion on methods for distributing and testing a purely digital version of the reference phantom Test digital reference object on 3 rd 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
