FIELD-RT

FIELD-RT evaluates target volume delineation (TVD) accuracy in radiation therapy and provides quantitative and qualitative feedback to reduce intra- and interobserver variability and support training of clinical oncology trainees and consultants.

Key Features:

• Quantitative assessment: An analysis toolbox computes quantitative metrics of TVD performance relative to reference volumes and acceptable volume ranges.
• Qualitative assessment: The system provides qualitative evaluations of delineation quality alongside quantitative metrics.
• Visualizer: A visualizer enables detailed examination of individual delineations against reference contours and organs at risk (OARs).
• Structured report generator: Generates personalized, exportable reports summarizing individual trainee performance and feedback.
• Site-specific modules: Uses site-specific clinical cases with reference target volumes, acceptable volume ranges, and OAR definitions derived from consultant and senior trainee outlines.
• Automated performance evaluation: Automatically evaluates individual performance using defined feedback mechanisms.

Scientific Applications:

• Training and education: Provides personalized feedback to support continuous professional development of clinical oncology trainees and consultants.
• Quality assurance in radiotherapy: Assesses and aims to reduce intra- and interobserver variability in TVD to improve radiotherapy treatment quality.
• Performance monitoring: Enables measurement of trainee performance over time and generation of reports for longitudinal assessment.
• Validation study evidence: Pilot validation with 63 trainees demonstrated improved TVD performance following review of personalized feedback.

Methodology:

The platform computes quantitative and qualitative assessments via an analysis toolbox, compares delineations to site-specific reference target volumes and OAR outlines (with acceptable volume ranges derived from consultant and senior trainee contours), provides a visualizer for detailed comparison, and produces structured exportable reports delivering personalized feedback.
