Title:
歯科インプラントナビゲーション手術の追跡方法および装置
Document Type and Number:
Japanese Patent JP7202737
Kind Code:
B2
Abstract:
A calibration method and device for dental implant navigation surgeries, and a tracking method and device for dental implant navigation surgeries. The calibration method comprises: (110) acquiring the position of a scan area (304) with respect to a second visual marker (306) on the basis of the spatial position of a first visual marker (305) provided on a scan device (302), the spatial position of the second visual marker (306) provided in a surgical area (303), and a scan position of the scan area (304) scanned by the scan device (302); and (120) registering the position of the scan area (304) with respect to the second visual marker (306) with a three-dimensional scene to obtain a conversion matrix, and applying the conversion matrix to the tracking of a surgical instrument, so that the position change of a surgical instrument can be reflected in real time in the three-dimensional scene, without implanting a marker point in the body of a patient, even if the patient's head moves during the surgery, thereby achieving accurate real-time tracking of the surgical instrument.
