So far, we have developed a fluorescent x-ray computed tomography using a pinhole effect. However, since S/N of projection data is low due to insufficient fluorescent x-rays passing through a pinhole, we have not been able to reach the minimum detection limit required for measurement of biological samples. In this research, we introduced the multi-pinhole method to overcome the difficulty and devised a calibration method for precise reconstruction. We demonstrated its effectiveness using actual data which were acquired by the imaging system constructed at beamline AR-NE7A, KEK. We obtained the target detection limit of 0.05 mg/ml required for measuring biological samples. |
