Technical note: mobile CT scanner gantry for use in the operating room.

In modern neurosurgical practice, CT is a well established, important examination for planning surgery and perioperative care. Recently, CT scanners have been used for intraoperative imaging during craniotomy [1-6]. In this paper, we report a newly developed mobile CT scanner gantry with a modified fork-lift gantry carrier. This system enables the radiologist to obtain CT images during surgery or immediately after surgery in the operating room; for example, in patients who cannot be transferred to the ordinary scanner room in the radiology department.
