A Stereotactic Head Frame for Use with CT Body Scanners

A prototype stereotactic head frame has been constructed for use in conjunction with a computed tomographic (CT) body scanner. Interactive software has been developed to allow target delineation using a standard CT scanner computer and image display console. The mathematic equations fundamental to this software are described. In preliminary experiments, it has been demonstrated that this frame can accurately direct a probe to an appropriately delineated target in a series of CT scans. A theoretic method for determining accuracy is presented; results suggest that this system represents a significant improvement over classic methods of neurosurgical stereotactic localization.

Metabolic frame for use in an incubator

CONSIDERABLE TECHNICAL DIF'FICULTIES have plagued investigators wishing to collect 24-hour (or longer) urine output from infant girls, especially lowbirth-weight infants nursed in incubators. We found that Urine collection systems attached to the skin usually separate from the perineum within a couple of hours. Stool contamination may occur if the bowels move before the infant voids. Repeated application of adhesives to the skin can produce irritation and predispose to infection. A metabolic flame for use in an incubator has been designed. This flame prevents stool contamination of urine, obviates irritation of the skin, and allows changes of stool-soiled netting without removal of either the baby or flame from the incubator.
