测量了像素尺寸为25 μm × 25 μm的新型IP的灵敏度和衰减特性，以校准定量分析中的读出强度，并评估IP阅读器的读出效率。灵敏度与电子剂量呈良好的线性关系，动态范围约为五个数量级。然而，在IP阅读器的一个增益条件下，有效动态范围被限制在大约四个数量级。新IP的衰减特性与电子强度无关，并且由于衰减而导致的读出强度下降小于像素尺寸为50 μm × 50 μm的旧IP。此外，由重复读出引起的衰减特性与电子强度无关，并且在重复读出10次之后读出强度不为零。
The sensitivity and fading characteristics of the new IP, which had a pixel size of 25 μm × 25 μm, were measured to calibrate the read-out intensity in quantitative analysis and to estimate the read-out efficiency of an IP-reader. The sensitivity showed good linearity in electron dose and a wide dynamic range of about five orders. However, the effective dynamic range was restricted to about four orders under one gain condition of the IP-reader. The fading characteristic of the new IP was independent of the electron intensity, and the decrease of the read-out intensity due to the fading was smaller than with the old IP which had a pixel size of 50 μm × 50 μm. Furthermore, the fading characteristic caused by repeated read-out was independent of the electron intensity, and the read-out intensity did not reach zero after read-out was repeated 10 times.
