Abstract

A method of providing user guidance. First patient image data of a patient's body is obtained. A registration instruction indicative of where to acquire a registration point relative to a surface of the body is determined. Second patient image data of the body, having been acquired by an augmented reality device, is obtained. A transformation between coordinate systems of the first and the second patient image data is determined. Based on the transformation, display of the registration instruction on a display of the AR device is triggered such that a user of the AR device is presented an augmented view with the registration instruction being overlaid onto the patient's body. The augmented view guides the user where to acquire the registration point. Also disclosed are a computing system, a surgical navigation system, and a computer program product.
