Horizontal extension of the field-of-view in cone-beam tomography at a laboratory instrument

This paper presents a method for horizontally extending the field-of-view in cone-beam tomography to overcome the limitations of traditional detector sizes. The acquisition algorithms are implemented on an Exciscope Polaris phase-contrast micro-CT instrument, which ensures sufficient motion accuracy for horizontal extension solely reliant on stage positions, even at submicron voxel sizes. This innovation enables the construction of an automated data pipeline that bypasses the need for user input or image registration to recombine frames. Utilizing cloud computing for reconstruction, we efficiently handle large data sizes and computational demands. We demonstrate the method both with a reconstruction diameter of 12,500 voxels and with submicron voxel sizes, showcasing significant improvements in imaging capabilities.
