摘要
This poster contains the procedure to obtain micro-CTs and to image moving samples using the Medipix2 detector, with its corresponding results. The high granularity of the detector makes it suitable for micro-CT. We used commercial software (Octopus) to do the 3D reconstruction of the samples in the first place, and we worked on modifying free reconstruction software afterwards. Medipix has a very fast response ( similar to hundreds of nanoseconds) and high sensibility. These features allow obtaining nearly in-vivo high resolution (55m * 55m) images. We used an exposure time of 0.1 s for each frame, and the resulting images were animated. The High Energy Physics Group at UniAndes is a member of the Medipix3 collaboration. Its research activities are focused on developing set-ups for biomedical applications and particle tracking using the Medipix2 and Timepix detectors, and assessing the feasibility of the Medipix3 detector for future applications.
