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?

Oblique reformat • Anatomy is rarely predominantly aligned axially, sagitally, or coronally • Oblique reformation allows image display planes to be aligned to an anatomy’s principal axes Axial Oblique
Standard oblique reformat CTRL-Right Button to manipulate reformation
Comparing series and studies • Longitudinal analysis • Cross-sectional analysis
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
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
