Abstract

In this study, we introduce a novel spectroscopic CT scanning method using a 12x1 Timepix3 detector array with 1mm CdTe sensors in data-driven readout mode. It enables full-spectrum data acquisition and processing on standard laboratory computers, addressing challenges of varying absorption and data volume issues. Our approach involves an initial preclustering step, reducing data size with an efficient algorithm. We then employ dynamic pixel masking to limit photon collection, optimizing signal-to-noise ratios and reducing data load. This strategy enables comprehensive CT scans on standard computers, advancing spectroscopic CT imaging.
