概括
智能手机摄影仪测量测定人体平面的可靠性很好,但与放射测量的一致性不佳. 它是作为一个补充工具,而不是替代标准的负载型X射线图.
科学领域:
- 整形外科 整形外科 整形外科
- 医疗成像医学成像
- 生物机械工程 生物机械工程
背景情况:
- 盘平的诊断依赖于标准的放射测量.
- 基于智能手机的摄影测量为评估提供了一个潜在的替代方案.
- 评估智能手机摄影仪的准确性和可靠性至关重要.
研究的目的:
- 评估智能手机摄影仪测量的可靠性和诊断准确性.
- 为了比较智能手机衍生的测量与标准的放射性形角 (CPA).
主要方法:
- 对100名患者进行前性研究,将承重脚部放射图与智能手机照片进行比较.
- 测量包括从X射线图中获得的足角 (CPA) 和从智能手机图像中获得的摄影角 (P-APA).
- 使用ICC评估观察者间和观察者内部的可靠性;使用相关性评估的协议,CCC,Bland-Altman和Deming回归.
主要成果:
- 这两种方法的观察者内部和观察者间可靠性都很好 (ICC ≥ 0.900).
- 智能手机P-APA系统地高估了X射线CPA (31.8°对比21.8°),显示出强烈的相关性 (r=0.799) 但相对一致性较差 (CCC=0.222).
- 在ROC分析中,校准的P-APA在ROC分析中达到0.885的AUC,表明诊断准确度中等.
结论:
- 智能手机摄影计是可靠的,但不等价的CPA在平面人体的放射性评估的替代品.
- 显著的系统偏见和有限的协议排除了其作为重量轴承X射线相片的替代品的使用.
- 智能手机摄影测量可以作为查或远程医疗的补充工具,需要放射性确认才能确定确诊.

01:29Reliability and Validity
13.9K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

03:38Measurement: Standard Units
79.4K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...
