The puncture is a procedure of surgery to insert the catheter to the patient veins and pick up the cell from the patients. Doctor predicts the target vessel position of the patient and operates puncture approaching to it supported by ultrasound guided. It is required that the support system which is able to guide the head of puncture needle to target point in safety.The purpose of this research is to develop the ultrasound guided support system based on augmented reality (AR). Proposed system superimposes the ultrasound echo image and the head of puncture needle, which are created by three dimensional computer graphics, onto the real time images on monitor while performing puncture operation. By using this support system the doctor is able to predict the target point precisely and operates puncture safely. A prototype system is constructed and evaluate by a doctor. Moreover AR marker and adopter to attach the puncture needle are unified and algorithms to recognize the marker are enhanced. As a result, it is evident that proposed system can be available for the puncture procedure to support the doctor. However, improvement of control accuracy is a future work.
