A head holder for operative serial angiography.
An apparatus was developed to combine two functions--a versatile neurosurgical head clamp and a compact film changer for operative serial angiography. The construction costs were +15,000, and provided a programmer, six cassettes, and attachments to position the film changer over much of the skull surface. Exposures are obtained by a mobile x-ray machine.
