1 Digital Breast Tomosynthesis PACS/Workstation Vendor Perspective Ron Muscosky Product Line Manager for Carestream Health

2 Digital Breast Tomosynthesis Digital Breast Tomosynthesis (DBT) is an important emerging technology Carestream fully embraces DBT Interoperability is of utmost importance

3 Key Challenges Data Format Size Workflow Efficiency

4 Data Format Different modality used between acquisition device vendors (MG and CT) outside the US Proprietary format exams are stored in DICOM Secondary Capture format (slice or projection data is maintained in private attributes)

5 Data Format Different modality used between acquisition device vendors (MG and CT) outside the US Proprietary format exams are stored in DICOM Secondary Capture format (slice or projection data is maintained in private attributes) Vendor specific implementations Proprietary format limited to storage, since pixel data contains the center slice or projection

6 Data Format Different modality used between acquisition device vendors (MG and CT) outside the US Proprietary format exams are stored in DICOM Secondary Capture format (slice or projection data is maintained in private attributes) Vendor specific implementations Proprietary format limited to storage, since pixel data contains the center slice or projection DICOM Breast Tomosynthesis Image Storage SOP Class is now available to standardize the data format Modality vendors need to adhere to the DICOM standard

7 Data Format Different modality used between acquisition device vendors (MG and CT) outside the US Proprietary format exams are stored in DICOM Secondary Capture format (slice or projection data is maintained in private attributes) Vendor specific implementations Proprietary format limited to storage, since pixel data contains the center slice or projection End User: Potential interoperability issues between various vendor equipment Decide how store data moving forward and how to deal with priors DICOM Breast Tomosynthesis Image Storage SOP Class is now available to standardize the data format Modality vendors need to adhere to the DICOM standard

9 Data Format 2D Synthetic Images can be stored as MG or BTO no conversion available between formats

10 Data Format 2D Synthetic Images can be stored as MG or BTO no conversion available between formats Implementation needs to consider both formats Hanging protocols, prefetching, and routing of images need to consider both formats

11 Data Format 2D Synthetic Images can be stored as MG or BTO no conversion available between formats Implementation needs to consider both formats Hanging protocols, prefetching, and routing of images need to consider both formats Standard format needs to be decided upon IHE could be the place to define this

12 Data Format 2D Synthetic Images can be stored as MG or BTO no conversion available between formats Implementation needs to consider both formats Hanging protocols, prefetching, and routing of images need to consider both formats End User: Potential interoperability issues between various vendor equipment Standard format needs to be decided upon IHE could be the place to define this

13 Data Format 2D Synthetic Images can be stored as MG or BTO no conversion available between formats Implementation needs to consider both formats Hanging protocols, prefetching, and routing of images need to consider both formats Standard format needs to be decided upon IHE could be the place to define this End User: Potential interoperability issues between various vendor equipment End User: MG format recommended for backwards compatibility Ultimately needs to be standardized

14 Data Size DBT data is significantly larger than FFDM data DBT data size can vary significantly between vendors

15 Data Size DBT data is significantly larger than FFDM data DBT data size can vary significantly between vendors Review system specifications Review data storage and routing optimization

16 Data Size DBT data is significantly larger than FFDM data DBT data size can vary significantly between vendors Review system specifications Review data storage and routing optimization Update system specifications Use of lossless compression when transferring and storing data Update intelligent data routing rules with minimal data duplication ; especially important for teleradiology and multi-site facilities

17 Data Size DBT data is significantly larger than FFDM data DBT data size can vary significantly between vendors Review system specifications Review data storage and routing optimization End User: Evaluate network bandwidth/performance Evaluate local and archive storage sizing Evaluate data retention Update system specifications Use of lossless compression when transferring and storing data Update intelligent data routing rules with minimal data duplication ; especially important for teleradiology and multi-site facilities

18 Data Size DBT data is significantly larger than FFDM data DBT data size can vary significantly between vendors Review system specifications Review data storage and routing optimization Update system specifications Use of lossless compression when transferring and storing data Update intelligent data routing rules with minimal data duplication ; especially important for teleradiology and multi-site facilities End User: Evaluate network bandwidth/performance Evaluate local and archive storage sizing Evaluate data retention End User: 1 Gigabit network recommended Choose appropriate slice/plane thickness Size local storage/archive accordingly

19 Workflow Efficiency Different vendor data will need to be compared, but no interoperability guidelines exist for DBT as they do for FFDM DBT exams contain significantly more data than FFDM exams, so specialized tools are needed to optimize reading and help localize pathology

20 Workflow Efficiency Different vendor data will need to be compared, but no interoperability guidelines exist for DBT as they do for FFDM DBT exams contain significantly more data than FFDM exams, so specialized tools are needed to optimize reading and help localize pathology Implementation of tools and unique capabilities to minimize manual manipulations

21 Workflow Efficiency Different vendor data will need to be compared, but no interoperability guidelines exist for DBT as they do for FFDM DBT exams contain significantly more data than FFDM exams, so specialized tools are needed to optimize reading and help localize pathology Implementation of tools and unique capabilities to minimize manual manipulations End User: Different vendor data displayed in a dissimilar manner increases the time to read exams Lack of tools creates fatigue and an inefficient reading environment
