  4. What is Grayscale Standard Display Function? When exporting with GSDF; The image is exported with the promise that it will be displayed on a Standard Display Optimizing Export Image Quality - Shreelaxmi

  5. The GSDF Standard Display The final image processing steps take place in the Standard Display What if there is no Standard Display Available? Optimizing Export Image Quality - Shreelaxmi

  6. GSDF- Some Assembly required Would you use your new table without unpacking it? It would work? Optimizing Export Image Quality - Shreelaxmi

  7. It is very rare that the display systems are Standard Displays. Especially in the value segment market, most of the review station monitors are General Displays. Displays Systems • Customers demand for an alternative solution from vendors. • Display Systems can be categorized into Standard Displays (GSDF-Calibrated) and General Displays (Non-GSDF-Calibrated) Optimizing Export Image Quality - Shreelaxmi

  8. Solution - Export IQ Optimization • “Export Image Quality Optimization” provides :- • Customized LUT for a wide range of brightness luminance to support the Generic Displays. • A wizard to guide the selection of appropriate LUT for the destination. Optimizing Export Image Quality - Shreelaxmi

  9. Proposal - Workflow Enhancement • GSDF Calibrated review station. Start Set to use GSDF compensation. Exit Optimizing Export Image Quality - Shreelaxmi

  10. Proposal - Workflow Enhancement • Non GSDF Calibrated review station Start Regenerate for each LUT luminance Create a new study + Add regenerated images. Look for the best viewed image Export the study to Review station. Review station. Set the export compensation. Exit Optimizing Export Image Quality - Shreelaxmi

  12. How Export fits into the architecture: Optimizing Export Image Quality - Shreelaxmi

  13. An Analogy Same car viewed with a “Standard Display” or an appropriate export LUT is like applying the final coat of paint Viewing a Raw GSDF image is like a car with just the primer coat Optimizing Export Image Quality - Shreelaxmi

  14. Example Images Raw GSDF images are too contrasty, over gained, and appear grainy With the appropriate LUT the image is smoother and appears like it did on the system Optimizing Export Image Quality - Shreelaxmi

  15. A substitute “Standard Display” Provided by a User selected Export LUT + Generic Display Export LUT + a Generic Display approximates a “Standard Display” Optimizing Export Image Quality - Shreelaxmi

  16. Benefits • Export LUT + a Generic Display approximates a “Standard Display” • Supports GSDF for a Standard Display. • It is a one time task usually done by a doctor with the help of a Field Service Engineer (FSE). Future exports will use the selected settings. • There need to be an alternative setting available to facilitate this LUT selection at any point of time. Optimizing Export Image Quality - Shreelaxmi

  17. Conclusion • Even though the DICOM GSDF continues to address the issues related to differences in display characteristics, there are situations where a different solution may be needed. • The proposed solution enhances the DICOM GSDF by addition of a wide range of LUTs. • This helps in optimizing the exported image quality and hence provides the potential for better patient care.
