Having to pay attention to and play the role of "calibration record" as "basis" and "criterion" 应重视发挥“校准记录”的“依据”和“判据”作用
ASAP standards is a set of widely-agreed calibration criterion in industry. ASAP标准是一套得到工业界广泛认可的匹配标定规范。
Methods Routine maintenance and periodic calibration were performed using photometer and automatic calibration software according to American Association of Physicists in Medicine Task Group 18 ( AAPM TG18) test patterns and evaluating criterion. 方法参考美国医学物理学会第18工作组(AAPMTG18)制定的测试图和质量评估标准,利用光度计、显示器校正软件,对3种型号的BARCOCRT灰阶显示器进行季度性定量检测。
In order to optimize the calibration set of sample and enhance the precision of the model, 18 abnormal spectrums which were produced from subjective and objective factors were removed from calibration sample set based on mahalanobis distance and forecast concentration residual criterion. 为了优化校正集,提高模型的预测精度,用基于马氏距离准则和基于预测浓度残差准则相结合的方法剔除了18条因各种主客观因素产生的异常光谱。
