A computer-implemented medical method for generating augmentation information relating to a medical image, using the output of an augmented reality device having an output unit for outputting the augmentation information, the method comprising executing, on at least one processor of at least one computer (9, 11), the following steps: a) patient medical image data is acquired (S11; S21) which describes a patient image of an anatomical body part of a patient; b) geometric model data is acquired (S12; S22) which describes a geometric model of at least part of the patient's body, wherein the geometric model data is acquired from atlas data describing the at least part of the patient's body; c) the patient image is registered (S13; S23) with the geometric model; d) augmentation information is output (S14; S25) using the output unit of the augmented reality device based on a result of registering the patient image with the geometric model and is displayed, by a display or projector unit comprised in the output unit, as an overlay on a real image which describes the physical scene in the field of view of the augmented reality device or is acquired digitally and rendered on the output unit; e) medical procedure data is acquired which describes an envisaged medical procedure to be carried out on the patient; and device control data describing a control parameter of a medical device (3; 4) is acquired based on the medical procedure data, wherein the augmentation information corresponds to the device control data; or device placement data describing a spatial relationship between a medical device (3; 4) and at least part of the patient's body is acquired based on the medical procedure data, wherein the augmentation information corresponds to the device placement data. a) patient medical image data is acquired (S11; S21) which describes a patient image of an anatomical body part of a patient; b) geometric model data is acquired (S12; S22) which describes a geometric model of at least part of the patient's body, wherein the geometric model data is acquired from atlas data describing the at least part of the patient's body; c) the patient image is registered (S13; S23) with the geometric model; d) augmentation information is output (S14; S25) using the output unit of the augmented reality device based on a result of registering the patient image with the geometric model and is displayed, by a display or projector unit comprised in the output unit, as an overlay on a real image which describes the physical scene in the field of view of the augmented reality device or is acquired digitally and rendered on the output unit; e) medical procedure data is acquired which describes an envisaged medical procedure to be carried out on the patient; and device control data describing a control parameter of a medical device (3; 4) is acquired based on the medical procedure data, wherein the augmentation information corresponds to the device control data; or device placement data describing a spatial relationship between a medical device (3; 4) and at least part of the patient's body is acquired based on the medical procedure data, wherein the augmentation information corresponds to the device placement data. device control data describing a control parameter of a medical device (3; 4) is acquired based on the medical procedure data, wherein the augmentation information corresponds to the device control data; or device placement data describing a spatial relationship between a medical device (3; 4) and at least part of the patient's body is acquired based on the medical procedure data, wherein the augmentation information corresponds to the device placement data.
