摘要

研究了CdZnTe半导体探测器在x射线诊断能量范围内的灵敏度响应，目的是优化这些固态电离器件的图像质量参数。测量了检测到的信号和噪声贡献，并将其与管设置电流参数联系起来。此外，还通过实验确定了探测器的对比度。实验结果表明，CdZnTe探测器具有高电阻率、高信噪比和高对比度分辨率的特点。因此，它们似乎是成像应用的潜在候选者，如x射线数字放射照相、双能放射照相和计算机断层扫描(CT)。

Sensitometric response of CdZnTe detectors for digital radiography

The sensitometric response of the CdZnTe semiconductor detectors, within the X-ray diagnostic energy range, have been studied with the aim of optimizing the image quality parameters of these solid state-ionization devices. The detected signal and noise contributions were measured and related to the tube setting current parameters. Furthermore, the detector contrast has been experimentally determined. The experimental results indicate that CdZnTe detectors have high resistivity, high signal-to-noise ratio, and high detector contrast resolution. Therefore, they appear to be potential candidates for imaging applications with applications in X-ray digital radiography, dual-energy radiography, and computed tomography (CT).
