Precise measurements with the Vanguard Motion Analyzer were made to determine the position of the pineal gland as shown on the Polaroid displays of 145 normal scans. The relatively midline positions of the gland are expressed in terms of percentage shift of the gland in these 145 normal cases is defined by a mean value of 0.8% with a standard deviation of 0.6%. More than 99% of normal CT scans can be expected to show a percentage shift of 2.6% or less.
使用先锋运动分析仪进行精确测量，以确定松果体的位置，如145次正常扫描的宝丽来显示屏所示。腺体相对中线的位置以腺体在这145例正常病例中的百分比偏移来表示，其平均值为0.8%，标准差为0.6%。预计超过99%的正常CT扫描显示的百分比偏移为2.6%或更低。
