Development and early trials of real-time CT fluoroscopy

A CT fluoroscopy system that permits real-time monitoring of CT images was developed. In phantom studies the images were displayed at a rate of 6 per s, with a delay time of 0.67 s. Early clinical trials in aspiration of intracranial haematoma and brain tumour biopsy indicated that CT fluoroscopy is useful for CT-guided intervention on the central nervous system.
