| 12 | Techniques based on imaging serial sections of brain tissue provide |
| 13 | insight into brain structure and function. However, to compare or |
| 14 | combine it with results from three dimensional imaging methods such |
| 15 | data requires reconstruction into a volumetric form. Currently, |
| 16 | there are no tools for performing such a task in a streamlined way. |
| 17 | |
| 18 | Here we propose the Possum volumetric reconstruction framework which |
| 19 | provides a selection of 2D to 3D image reconstruction routines |
| 20 | allowing one to build workflows tailored to one's specific |
| 21 | requirements. The main components include routines for |
| 22 | reconstruction with or without using external reference and |
| 23 | solutions for typical issues encountered during the reconstruction |
| 24 | process, such as propagation of the registration errors due to |
| 25 | distorted sections. We validate the implementation using synthetic |
| 26 | datasets and actual experimental imaging data derived from publicly |
| 27 | available resources. We also evaluate efficiency of a subset of the |
| 28 | algorithms implemented. |

| 30 | The Possum framework is distributed under MIT license and it |
| 31 | provides researchers with a possibility of building reconstruction |
| 32 | workflows from existing components, without the need for low-level |
| 33 | implementation. As a consequence, it also facilitates sharing and |
| 34 | data exchange between researchers and laboratories. |
