Although the imaging of luminescence emitted in water during irradiation of protons and carbon ions is a useful method for range and dose estimations, the intensity of the images is relatively low due to the low photon production of the luminescence phenomenon. Therefore, a relatively long time is required for the imaging. Since a fluorescent dye, fluorescein, may increase the intensity of the optical signal, we measured the luminescence images of water with different concentrations of fluorescein during irradiation of protons and carbon ions and compared the results with those by measurements with water.

在质子和碳离子辐照期间增加荧光素的光信号强度

虽然在质子和碳离子辐照期间在水中发射的发光成像是用于范围和剂量估计的有用方法，但由于发光现象的光子产生量较低，因此图像的强度相对较低。因此，成像需要相对较长的时间。由于荧光染料荧光素可能会增加光信号的强度，我们测量了质子和碳离子辐照期间不同浓度荧光素的水的发光图像，并将结果与​​用水测量的结果进行比较。
