Image generation system and positioning used for medical applications using a reference unit which is fixed to the patient's head

摘要

(57) Abstract Position of the medical instrument for the body of the patient is monitored, the system which displays at least one image among the multiple images of the body of the patient who records beforehand according to the position of this medical instrument, is disclosed. With one execution configuration, as for the system in order not to move vis-a-vis the body of the patient, it is locked, it includes the standard unit which almost is firm vis-a-vis the operation region which is made target. In addition as for the system, the remote unit which is installed in the medical instrument is included. Making the field generator be related with standard unit and remote unit on the one hand, it is possible to generate position characteristic field in the field where it includes the target operation region. In addition making the field sensor of one be related or more with standard unit and remote unit on the one hand, responding to the existence of position characteristic field, that it is possible also to generate the sensor output signal of one or more which displays the field which it detects. The position data where displays of the sensor output signal and the position transducer which leads the relative position of standard unit and remote unit which is generated is generated. Responding to this position data, the output display which joints to the position transducer among the images which record beforehand displays one image at least.
