ULTRASONIC DIAGNOSTIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus, grasping a three-dimensional shape in real time. SOLUTION: The tip part of an insert part 103 is provided with an ultrasonic vibrator 107 driven by a DC motor 109. A rotation signal indicating the rotating angle of the DC motor 109 is inputted to an ultrasonic image processing part 121 through a signal line 111 disposed in an ultrasonic cable 105 extended from the side of an operating part 102 of an endoscope 101. An echo signal obtained from the ultrasonic vibrator 107 is inputted to the ultrasonic image processing part 121 through the signal line 111. A position detecting catheter 117 having a magnetic sensor 116 at the tip is passed through a treatment tool channel 115 of an endoscope 101. A position signal detected by the magnetic sensor is inputted to the ultrasonic image processing part 121 by a position signal cable 118 in the position detecting catheter 117. A magnetic source 119 is provided in an external position of the endoscope and connected to the ultrasonic image processing part 121. COPYRIGHT: (C)2005,JPO&NCIPI
