All of the images were acquired on Hologic equipment (Selenia Dimensions). They include the Secondary Capture objects (SCO) produced by the modality for the tomo projections and reconstructed slices, which contain the payload in private data elements, as well as the corresponding standard DICOM Breast Tomography objects (BTO) converted retrospectively by the vendor from the SCOs (with the assistance of Jeffrey Hanson). There are no corresponding standard format projection images available at this time, but these will be added to the collection if and when the vendor is able to produce them. Dicom Conformance statements are available from the vendor.
All of the files have been de-identified, initially by the site and again prior to distribution, following the DICOM PS 3.15 2011 Basic Application Level Confidentiality Profile, including modifications of the dates (Retain Longitudinal Temporal Information With Modified Dates Option) and retention of safe private attributes (Retain Safe Private Option). Descriptors have been retained and manually checked (Clean Descriptors Option). The tool used for the final de-identification was the PixelMed DicomCleaner.
The images contain some deficiencies with respect to DICOM conformance, which will be reported by validators such as dciodvfy. The errors include various incorrect workflow-related code sequences, which in some cases are missing mandatory elements, and in other cases use non-standard private coding schemes that are not designated with a 99 prefix. Some private elements exceed the permissable length of their explicit value representation. Some spacing and magnification related attributes in the FFDM images do not correspond mathematically. In the tomography images, the Frame Content functional group is missing; arguably this is permissible after CP 994 though may still be reported as an error by validators. The orientation vectors are encoded by the vendor with limited precision and may fail checks that they are unit vectors as a consequence. More strict validation of the FFDM images according to the IHE Mammography Image profile (e.g., with "dciodvfy -profile IHEMammo") will result in further errors being reported, but these are largely a consequence of the de-identification process (e.g., removal of the Patient Age, Operator Name, Institution Name, etc.).
For each case, all of the uncompressed Explicit VR Little Endian Transfer Syntax PS 3.10 DICOM files are grouped together in a single tar file, which is then bzip2 compressed. Recent versions of compression tools such as Power Archiver for Windows and Stuffit Expander for Macs support bzip2'd and tar'd files. Most modern Unix systems and Macs already have bzip2 and tar utilities installed. If not, command line utilities can be obtained from the bzip2 site. Windows executables are also available here.
