Summary
Pathologists extensively use novel navigation features in digital pathology workstations. Understanding these digital navigation patterns is key to optimizing workstation design for efficient whole-slide image diagnosis.
Area of Science:
- Digital pathology
- Human-computer interaction
- Medical informatics
Background:
- Developing efficient digital pathology workstations requires understanding how pathologists navigate whole-slide images.
- Previous studies have not fully characterized emergent navigation patterns among experienced digital pathologists.
Purpose of the Study:
- To study the navigation patterns of pathologists diagnosing whole-slide images.
- To develop a conceptual model of digital slide navigation.
- To identify new navigation patterns in experienced digital pathologists.
Main Methods:
- Five pathologists diagnosed four cases while vocalizing their thought processes.
- Navigation actions within digital slides were recorded and categorized.
- Analysis focused on recurring actions and their frequencies.
Main Results:
- Pathologists frequently reused navigation actions, but with varying occurrences.
- Slow panning along structures or systematic area coverage was the most common action (30.2%).
- 49% of actions occurred in the navigation overview, and 38% utilized features not available with conventional microscopes.
Conclusions:
- Digital pathology workstations' new navigation features are extensively utilized.
- Categorizing navigation actions aids in prioritizing user interface designs.
- This framework helps understand diverse pathologist navigation styles.
