Blending Presentation State introduction
Explore the concept of Parametric Blending Presentation State Storage, which allows showcasing spatial relationships between parametric maps and structural images while retaining usability. This innovative method involves blending different data sets, applying thresholds, and highlighting important areas for surgery and therapy planning. Learn how to combine anatomical images with parametric maps and DTI maps for effective visualization in medical imaging.

Supplement 189: Parametric Blending Presentation State Storage 1
Overview Objective Input data Blending operation Example 2 Blending Presentation State introduction
Objective Allowing to show spatial relationship of the parametric maps and structural images without loosing the ability to use: Geometry Spatial and Parametric Information Thresholds Major usage for Surgery and Therapy planning Is Modality independent 3 Blending Presentation State introduction
Input Data Describing the different information sets that will be blended: Structural dataset(s) for anatomy Parametric Maps for Functional Information 4 Blending Presentation State introduction
Blending operation Apply Threshold to highlight the important areas Supports the use of the Color information in the input datasets Blends the different datasets in specified order without losing the color information 5 Blending Presentation State introduction
Blending operation Requires Frame of Reference Supports usage of Padding Graphics overlays Segmented Color LUT description Real World value measurements Expects CP 1584 to be finalized for color support in Parametric maps. 6 Blending Presentation State introduction
Example Use case is brain mapping for pre-treatment planning. The goal is to visualize white matter, eloquent cortex for language with respect to the anatomy - - White matter is done by Color DTI Eloquent cortex is done by multiple language fMRI paradigms Anatomy is post contrast T1 - Blending Presentation State introduction 7
