Direct sagittal (positional) computed tomography of the head

A new method for positioning the head of the patient in the gantry of a fast wholebody scanner is reported, whereby reproducible direct sagittal scans of the head can be obtained and all disadvantages of mathematically reconstructed views can be avoided. There are also the marked advantages that the midline and parasagittal structures can be evaluated without artifacts, and that rapid sequence CT or computed angiotomography of an intracranial lesion can be performed with the same density and spatial resolution comparable to the lateral plane of conventional carotid and vertebral angiography.
