PROFILE
Andrew Howe
Over six months, contributed to OpenwaterHealth/OpenLIFU-python by building and refining backend systems for medical imaging workflows. Developed features such as robust DICOM-to-NIfTI conversion, database-backed user management, and protocol access control, emphasizing data integrity and security. Applied Python, YAML, and static typing to improve serialization, enforce type safety, and streamline data modeling. Enhanced maintainability through code refactoring, expanded unit testing, and improved documentation. Integrated context management for safer database operations and introduced structured handling for materials and segmentation methods. These efforts reduced manual intervention, improved reliability, and established a scalable foundation for future enhancements in imaging data pipelines.

6 Commits • 2 Features
Nov 1, 2025November 2025: OpenLIFU-python delivered a robust DICOM-to-NIfTI workflow and improved resource safety, strengthening medical imaging data processing and maintainability. Key features include detection and conversion of DICOM to NIfTI with accurate affine handling, LPS-to-RAS conversions, and automatic integration in the write flow, complemented by expanded test coverage and a dedicated util module for conversion logic. In addition, database resource allocation was refactored to use context management, reducing risks and pylint warnings. Overall, the month delivered tangible business value by streamlining imaging data pipelines, improving reliability, and reducing manual intervention.
