信道化霍特林观测器(CHO)在许多CT检测/分类任务中与人类观察者的表现有很好的相关性，但在常规CT质量控制和性能评估中尚未被广泛采用，这主要是因为缺乏一个易于使用、高效和有效的软件工具。我们开发了一个高度自动化的解决方案-CT图像质量评估和协议优化(CTPro)，这是一个基于Web的软件平台，包括CHO和其他传统图像质量评估工具，如调制传递函数和噪声功率谱。该工具可以让研究和临床社区轻松访问CHO，并实现高效、准确的图像质量评估，而无需安装额外的软件。通过比较临床光子计数CT和传统能量积分CT的低对比度检测能力，发现UHR-T3D的d‘比有IR的EID-CT高6.2%(p=0.047)，没有IR的d’低4.1%(p=0.122)。
The Channelized Hotelling observer (CHO) is well correlated with human observer performance in many CT detection/classification tasks but has not been widely adopted in routine CT quality control and performance evaluation, mainly because of the lack of an easily available, efficient, and validated software tool. We developed a highly automated solution – CT image quality evaluation and Protocol Optimization (CTPro), a web-based software platform that includes CHO and other traditional image quality assessment tools such as modulation transfer function and noise power spectrum. This tool can allow easy access to the CHO for both the research and clinical community and enable efficient, accurate image quality evaluation without the need of installing additional software. Its application was demonstrated by comparing the low-contrast detectability on a clinical photon-counting-detector (PCD)-CT with a traditional energy-integrating-detector (EID)-CT, which showed UHR-T3D had 6.2% higher d’ than EID-CT with IR (p = 0.047) and 4.1% lower d’ without IR (p = 0.122).
