    摘要: A method of aligning a C-arm (26) of an image intensifier for rotation in a selected plane, the C-arm having a transmitter (22) mounted at one end and a receiver (24) mounted at an opposite end, comprising: identifying the selected plane by viewing the location of bony structure (12) with the image intensifier; and aligning indicia disposed on a radio-opaque reticle (25) covering at least a portion of the receiver with the selected plane, the indicia being aligned with the plane of rotation of the C-arm, thereby aligning the plane of the C-arm with the selected plane.

    摘要: A method and system for detecting the proximity of a nerve to a proximity electrode and status of nerve. The method of detecting the status of the nerve (30) includes the steps of placing an electrode near the nerve (32); providing an electrical signal having varying current levels to the electrode (34) to stimulate the nerve; measuring an EMG response of the nerve for the applied current (36); mapping the EMG responses (38) of the nerve for the applied electrical signal for a fixed latency; and determining the status of the nerve based on the mapping of the responses (42).

    摘要: A method for detecting the presence of a nerve adjacent the distal end of at least one probe, comprising: determining relative neuro-muscular response onset values for a plurality of spinal nerves; emitting a stimulus pulse from a probe or surgical tool; detecting neuro-muscular responses to the stimulus pulse in each of the plurality of spinal nerves; and concluding that the electrode disposed on the distal end of the at least one probe is positioned adjacent to a first spinal nerve when the neuro-muscular response detected in the first spinal nerve is detected as a current intensity level less than or equal to a corresponding neuro-muscular response onset value of the first spinal nerve.
