CDRH's Office of Science and Engineering Laboratories (OSEL) - Source Code Sharing

Source code developed by government employees is by definition "public domain", and therefore should be free, open, and easily available to all. To accomplish this goal, CDRH advocates that developers publish and maintain source codes in web-accessible software repositories. To promote the visibility and transparency of CDRH's computational research, developers are also encouraged to "release early and often" in accordance with open source software development philosophy. This approach creates a tight feedback loop between developers and testers or users, which results in higher quality software being developed more readily.

There are currently two CDRH computational research projects where the source code is available through external software repositories. They are:

TheraPydisclaimer icon

A collection of Python scripts developed to model the evolution of chemical and physical inhomogeneities, i.e. microstructure, in drug-polymer composites used as controlled drug release coatings. This set of tools can reduce empiricism in materials selection and process design, providing a facile and efficient means to tailor the underlying microstructure and achieve a desired drug release behavior.

MC-GPUdisclaimer icon

X-ray imaging system simulation code implementing an accurate Monte Carlo x-ray transport algorithm that can be efficiently executed in a state-of-the-art Graphics Processing Unit (GPU). MC-GPU generates clinically-realistic projection or tomographic images of the human anatomy that can be used in the assessment and optimization of imaging systems, as shown in Medical Physics 36, p. 4878-4880 (2009).
