Disclosed is a method for providing guidance to a user on where to arrange an object of interest in an operating room. The method includes obtaining a spatial pose of an item arranged within the operating room and obtaining a requirement on a spatial relationship between an object of interest and the item. The method also includes determining (a) a first spatial portion in which the object of interest is recommended to be arranged, the first spatial portion being larger than the object of interest, and/or (b) a second spatial portion in which the object of interest is not allowed to be arranged. Moreover, the method includes triggering display of a visualization of the first and/or second spatial portion to guide a user on where to arrange the first object of interest in the operating room.

Technique for providing guidance to a user on where to arrange an object of interest in an operating room

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.

Technique of providing user guidance for obtaining a registration between patient image data and a surgical tracking system

A method of calibrating a registration of an augmented reality devicecomprised in a surgical navigation systemis provided. The method comprises obtaining a first transformationbetween a coordinate systemof the augmented reality deviceand a reference coordinate systemof the surgical navigation system, a second transformationbetween a coordinate system of a reference objectand the reference coordinate systemand obtaining geometrical properties of the reference object. The method further comprises determining a visual representationof the reference objectto be displayed by the augmented reality deviceand obtaining at least one first viewing directionof a user using the augmented reality device, the at least one first viewing directionbeing associated with the reference coordinate system. The method comprises determining a calibrated first transformation, which is a transformation between the coordinate systemof the augmented reality deviceand the reference coordinate system

Technique for calibrating a registration of an augmented reality device

A method, device, and computer program product for capturing projection images of an object are provided. An x-ray beam source is moved by a control unit on a path into a plurality of positions, in which an x-ray beam is transmitted. An x-ray beam detector is moved by the control unit into a plurality of positions, in which the x-ray beam, penetrating the object, is detected. The x-ray beam source and/or the x-ray beam detector are moved on a calculated path around the object, at a constant distance between the x-ray beam source and the x-ray beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central x-ray beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the x-ray beam detector and the object is minimized.
