PROFILE
Leonardo Campos
Leonardo Campos developed extensibility and GPU-accelerated image segmentation features for the OHIF/Viewers and cornerstone3D repositories, focusing on robust workflow and imaging capabilities. He introduced onExit hook support and improved extension management, enabling extensions to respond dynamically to mode changes. In cornerstone3D, he implemented GPU-accelerated grow-cut segmentation tools using WebGPU, enhancing performance for large-scale medical imaging. Leonardo also aligned orientation markers across stack and volume viewports in OHIF/Viewers by simplifying orientation logic, improving reliability and maintainability. His work leveraged JavaScript, TypeScript, and GPU computing, demonstrating depth in both backend and front-end development for medical imaging platforms.

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.
