Motivation
- In general, for image reconstruction in ultrasound, only magnitude (intensity) of reflections is considered.
- In this work a novel vector field concept is proposed which considers the reflection magnitude and directivity.
- A novel Reflection Directivity Visualization Tool for Improved Operator Workflow is proposed.
