eContour

eContour provides image-based contouring guidance and annotated case examples to support evidence-based target and organ-at-risk delineation for radiation oncology treatment planning.

Key Features:

• Interactive 3D Visualization: Displays JPEG images generated from DICOM files in a viewer that enables scrolling through three-dimensional patient image sets.
• Image Manipulation Tools: Allows toggling of contours and overlaying of images together with radiation dose distributions.
• Evidence-Based Guidelines: Associates each case with brief written content that references published contouring guidelines for delineation.
• Technology Stack: Implements viewer and image handling using HTML5, Python, and JavaScript.

Scientific Applications:

• Radiation oncology treatment planning: Supports precise target and organ-at-risk delineation for radiation therapy planning.
• Point-of-care decision support: Provides image-guided, case-based guidance to inform contouring decisions at the time of care.
• Standardization and quality improvement: Addresses variation in contouring quality by providing real patient cases and guideline-referenced examples to promote consistent delineation practices.

Methodology:

Implementation uses HTML5, Python, and JavaScript to render JPEGs generated from DICOM files, enabling scrolling through three-dimensional image sets and overlaying contours and radiation dose distributions.
