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.
开发了一种兼具两种功能的装置——一种多功能神经外科头部夹钳和一种用于术中连续血管造影的紧凑型换片机。其建造成本为15000美元,配备了一个编程器、六个暗盒以及用于将换片机定位在大部分颅骨表面的附件。通过移动X光机进行曝光。
