PROFILE
Leonardo Campos
Worked on OHIF/Viewers and cornerstone3D repositories to deliver extensible imaging platform features and robust orientation marker alignment. Developed GPU-accelerated image segmentation tools using WebGPU, introducing grow-cut segmentation with sphere and bounding box methods to cornerstone3D, and updated APIs and utilities for scalable medical imaging workflows. Enhanced OHIF/Viewers by implementing onExit hook support and extensionManager propagation, enabling extensions to respond to workflow mode changes, and fixed a parameter propagation bug for reliable route initialization. Improved orientation marker consistency by recalculating orientation from viewport canvas coordinates, simplifying code and reducing edge cases. Utilized TypeScript, JavaScript, and React throughout development.

Aug 1, 2025Monthly summary for 2025-08: Key feature delivered: orientation markers alignment across OHIF/Viewers stack and volume viewports. Removed camera rotation and flip logic; orientation is now calculated directly from viewport canvas coordinates, resulting in consistent orientation labels across both stack and volume viewports. This change reduces edge cases, improves reliability, and enhances user experience when navigating imaging datasets. Commit 266b1f58f01ac6742a9bb40dda28459e7cddc683: feat(orientationMarkers): improved the orientation markers with a simplified version (#5328).

Dec 1, 2024December 2024 monthly recap: Delivered core platform extensibility and GPU-accelerated image segmentation capabilities for OHIF and cornerstone3D. Implemented onExit hook support and extensionManager propagation to enable extensions to react to mode changes, fixed a critical parameter propagation bug in display sets for robust default route initialization, and introduced GPU-accelerated grow-cut segmentation tools via WebGPU with API and utility updates. These changes improve workflow reliability, extension ecosystems, and scalability for large-scale imaging deployments.
