New transducers for intraoperative spinal sonography. Technical note.
Although ultrasonography during spinal cord surgery has been widely accepted, it still has limitations in clinical application because of the size of the transducers needed and the immersion method. The authors report on newly designed microprobe transducers used to evaluate intramedullary spinal cord lesions and to monitor surgical procedures. This microprobe system permitted the microscopic use of intraoperative ultrasonography without requiring saline immersion.
