To externally validate a hidden Markov model (HMM) for classifying gamma analysis results of in vivo electronic portal imaging device (EPID) measurements into different categories of anatomical change for lung cancer patients. Additionally, the relationship between HMM classification and deviations in dose‐volume histogram (DVH) metrics was evaluated.

使用EPID剂量测定法对肺癌患者进行基于伽马的解剖学变化分类的隐式马尔可夫模型的外部验证。

为了从外部验证隐马尔可夫模型（HMM），以便将体内电子门成像设备（EPID）测量的伽马分析结果分类为肺癌患者的不同类别的解剖变化。此外，还评估了HMM分类与剂量-体积直方图（DVH）指标偏差之间的关系。
