Extended Data Fig. 6: Effect of the relative direction of the capsule and the X-rays on the radioluminescence intensity.
From: A swallowable X-ray dosimeter for the real-time monitoring of radiotherapy
The test schematic (left column), the simulated power distribution of the fibre end (middle column), and the power detected by the detector (right column), with X-rays incident along the z-axis and the capsule rotating about the y-axis (a), the z-axis (b), and the x-axis (c). d. Power detected by the sensor versus angle of rotation of the capsule around the y-axis for a 50 kV or 6 MV beam. e, Average percent angular dependence of the dosimeter for different beam angles.
