Abstract
An ultrasound wireless positioning system is developed to localize the laparoscopic instruments inside the patient´s body. The cross correlation method applied for measuring time of flight of ultrasound bursts yields 1 mm resolution in determining the instrument position. The 90° or respectively 180° phase-shift is introduced after the first half of the ultrasound burst.
