Patient positioning for direct sagittal CT of the orbit parallel to the optic nerve.

A patient positioning technique for midsagittal brain scanning was modified to allow for direct sagittal computed tomography examinations of the orbit parallel to the optic nerve. High-resolution, artifact-free images are obtained that clearly depict all vital interfaces in sagittal cross sections. This technique is applicable to nearly all patients and does not present the many disadvantages of multiplanar reformating.
