    • For dental and facial imaging, a source of x-rays (14) or other penetrating radiation and a detector (20) are mounted opposite one another on a rotatable gantry (28), so that the head of the patient can be positioned between the source (14) and the detector (20), with the axis of rotation (36) of the gantry passing through the patient's head. The detector is longer in one direction than in the perpendicular direction, generally rectangular, and is rotatable between a position in which the long axis is transverse to the axis of rotation of the gantry and a position in which the long axis is generally parallel to the axis of rotation of the gantry. The length of the detector along the long axis is sufficient for fully detailed computed CT when the long axis is transverse, and for full-face CT when the long axis is parallel.
    • 对于牙科和面部成像,将X射线源(14)或其他穿透辐射源和检测器(20)彼此相对地安装在可旋转机架(28)上,使得患者的头部可以位于 源(14)和检测器(20),台架的旋转轴线(36)穿过病人的头部。 检测器在一个方向上比垂直方向上的长度大致为矩形,并且可以在长轴横向于台架的旋转轴线的位置和长轴大致平行于该位置的位置之间旋转 龙门架的旋转轴。 当长轴是横向时,沿着长轴的检测器的长度足以用于完全详细的计算CT,并且当长轴平行时,全长CT是足够的。
