摘要: We have designed and built an inexpensive, high-resolution, tomographic imaging system, dubbed the multi-module, multi-resolution or M3R. Slots machined into system shielding allow for interchange of pinhole plates, enabling to operate over a wide range magnifications with virtually any desired configuration. The flexibility allows optimization specific tasks also modifications necessary due improved detectors, electronics, knowledge construction (e.g., sensitivity optimization). provide overview M3R, focusing primarily on design construction, aperture calibration methods. Reconstruction algorithms will be described reconstructed images presented.
