Neurologic diagnosis using the 80-lens optical camera.

This article describes the clinical application of the 80-lens optical camera in the diagnosis of cerebral infarction, subdural hematoma, intracranial tumor, and hydrocephalus. The 80-lens camera is a simple noncomputerized addition to the Anger scintillation camera that permits an estimation of the cerebral blood flow. The study is noninvasive and quick, minimizing the effect of movement artifact and showing areas of either increased or decreased blood flow. Abnormal tumor vessels appear, and subdural hematomas show brain displacement away from the skull edge. Interpretation of blood flow pattern is not affected by scalp or skull trauma, eliminating a source of error incurred with static scans.

A new 80-lens oscilloscope camera for routine dynamic organ scintigraphy.

A simple, reliable, and cost-effective 80-lens photographic camera records dynamically from the oscilloscope of a scintillation camera without degradation of spatial resolution or data loss. Most physiologic events can be recorded completely and without interruption on a single 9 X 12-cm negative film as 40 sequential time-frames, using one of six available exposures per frame. In addition, 40 simultaneous sequential time-frames of four times the chosen duration may bracket a transient event with increased data density. The 80-lens camera has been used routinely for perfusion scintigraphy of brain, heart, liver, kidneys,and lungs with excellent results.
