4D laryngeal CT data.xlsx

Data set of laryngeal measurements taken from
31 people with Parkinson's disease (pwPD) of varying disease durations and severities, and 19 healthy controls. Participants were scanned in the supine position and pwPD were
scanned on the 'off' medication state. During a continuous CT acquisition
scanning period of 5 seconds, participants were instructed to produce five
short phonations of /i/ quickly and clearly. Images were re-constructed to
produce continuous multiplanar images of the larynx at 100ms per frame. We removed all data from the pre-vocalization
period. A fiducial marker was placed on the most medial aspect of the left and
right arytenoid cartilages. The data set includes the following measurements:

1. GA: The glottic
area in mm2 for each timepoint for each participant which was segmented
out using the Phillips IntelliSpace Portal software program.

2. IAD: The
inter-arytenoid distance in mm was defined as the Euclidean distance between
the left and right arytenoid cartilages for each timepoint.

3. LAM and RAM: Refers
to the interval distance moved in mm by the left and right arytenoids between
successive timepoints. Negative values refer to adduction movements towards the midline, while positive values are abduction movements away from the midline.Patient demographics are given as follows:Age - Given in years.Diagnosis - PD: Parkinson's disease; CON: ControlsDuration - Given in months.UPDRS - Refers to MDS-UPDRS part III motor scores.

本数据集收集了31位不同病程和严重程度帕金森病（pwPD）患者及19位健康对照者的喉部测量数据。受试者在仰卧位下接受扫描，且pwPD患者在‘关’药效状态下进行扫描。在5秒的连续CT采集扫描期间，受试者被要求迅速且清晰地发出五个/i/音的短促发音。图像被重建，以生成每帧100毫秒的连续多平面喉部图像。我们移除了所有发声前期的数据。在左、右声带软骨最内侧放置了一个参考标记。数据集包括以下测量指标：
1. GA：使用飞利浦 IntelliSpace Portal 软件程序对每个受试者在每个时间点的声门面积（单位：平方毫米）进行分割。
2. IAD：定义为每个时间点左、右声带软骨之间的欧几里得距离，单位为毫米。
3. LAM 和 RAM：指左、右声带在连续时间点之间移动的间距（单位：毫米），负值表示向中线靠拢的收缩运动，正值则表示远离中线的伸展运动。
受试者人口统计学信息如下：
年龄 - 以年为单位。
诊断 - PD：帕金森病；CON：对照组。
病程 - 以月为单位。
UPDRS：指MDS-UPDRS第三部分运动评分。
