The orientation of these lines of action was estimated in 9 healthy subjects, by reconstructing the muscle shape from a series of parallel sections obtained by MRI. In order to gain insight into sources of error, the lines of action of the masseter and medial pterygoid were estimated from two mutually perpendicular series of sectional images. Average results were compared with anatomical data from the literature. The results indicated that the accuracy of the estimate was principally dependent on the reliability of the reconstructions; the average accuracy of the estimated orientations was about 5 degrees.
通过对9名健康受试者的一系列MRI平行切片进行肌肉形状重建，估算这些作用力线的方向。为深入了解误差来源，从两个相互垂直的断层图像系列估算咬肌和翼内肌的作用力线。将平均结果与文献中的解剖学数据进行比较。结果表明，估算的准确性主要取决于重建的可靠性；估算方向的平均准确性约为5度。
