2 Neuroimage Analysis Center An NCRR National Resource Center Requisites, expectations and adaptations Clinicians and researchers need and expect imaging platforms to provide stock capabilities Window/level Pan/zoom Annotation Probe Measurement Oblique reformat Volume rendering Lightbox How do we adapt these concepts to a Slicer experience?

3 Neuroimage Analysis Center An NCRR National Resource Center Lightbox spx ?

4 Neuroimage Analysis Center An NCRR National Resource Center Standard lightbox viewing spx

5 Neuroimage Analysis Center An NCRR National Resource Center … with overlays

6 Neuroimage Analysis Center An NCRR National Resource Center … with annotations

7 Neuroimage Analysis Center An NCRR National Resource Center … with fiducials

8 Neuroimage Analysis Center An NCRR National Resource Center … with multiple reformations

9 Neuroimage Analysis Center An NCRR National Resource Center … with an editor X

10 Neuroimage Analysis Center An NCRR National Resource Center Oblique reformat Anatomy is rarely predominantly aligned axially, sagitally, or coronally Oblique reformation allows image display planes to be aligned to an anatomys principal axes Axial Oblique

21 Neuroimage Analysis Center An NCRR National Resource Center Applications Atlas construction Manual delineation Quality control Cross-sectional comparison of atlas subjects before and after aligning to common coordinate frame Cross-sectional comparison of atlas subjects to constructed atlas Atlas application Comparison of atlas to new subject Cross-sectional comparison of new subjects aligned with atlas Longitudinal analysis Response to therapy

22 Neuroimage Analysis Center An NCRR National Resource Center Image viewing is still predominantly 2D Native format of acquisition Precision dimensional measurements Multiplanar reformat (axial, sagittal, coronal) provides a natural (perhaps comfortable) navigation paradigm Lightbox provides a mechanism to display 3D relationships Oblique reformats provide a mechanism to mitigate 3D effects (improve accuracy of dimensional measurements) Longitudinal and cross-sectional comparisons build on the same framework of linked controls and coordinate frames Slicer3 allows all these capabilities to be layered due incorporation of coordinate frames at a fundamental level of the viewing pipeline
