20100208274 | Apparatus and method for the representation of an area on the surface of a patient's body - The invention is related to an apparatus for the representation of a geometrical figure on the surface of a patient's body that is situated on a support, comprising at least one projection device, by which a given geometrical figure can be projected onto the three-dimensional surface of the patient's body, at least one control device and at least one optical sensor device, by which the geometrical figure projected onto the surface of the patient's body can be acquired and the acquired data can be supplied to the control device, wherein the control device is realised to determine the three-dimensional coordinates of the geometrical figure projected onto the patient's body from the data acquired by the sensor device, and wherein the control device is realised to compare the determined three-dimensional coordinates of the geometrical figure projected onto the patient's body with desired three-dimensional coordinates. | 08-19-2010 |

20090292200 | APPARATUS AND METHOD FOR MARKING AN IRRADIATION FIELD ON THE SURFACE OF A PATIENT'S BODY - The present invention is related to an apparatus for marking an irradiation field on the surface of the patient's body, which was produced by means of a virtual 3D model of a patient's body, with a laser system for determining the coordinates of at least two reference points on the surface of the patient's body in a local coordinate system assigned to the apparatus, with an analysing and control unit which is realised to determine a transformation matrix for the transformation of arbitrary coordinates from the virtual coordinate system into the local coordinate system from the coordinates of the reference points in the local coordinate system and from coordinates of the reference points in a virtual coordinate system of the virtual 3D model of the patient's body, and wherein the analysing and control unit is further realised to transform coordinates from the virtual coordinate system into the local coordinate system with the transformation matrix, and to provide the transformed coordinates to the laser system. In addition, the present invention is also related to a corresponding method. | 11-26-2009 |

20090251709 | APPARATUS AND METHOD FOR THE REPRESENTATION OF AN AREA ON THE SURFACE OF A PATIENT'S BODY - An apparatus for the representation of an area on the three-dimensional surface of a patient's body, with a control device which provides three-dimensional coordinates of at least one area to be represented on the surface of the patient's body, wherein the area pre-sets a desired intersection area of a radiation area on the surface of the patient's body, characterised in that at least one projection device featuring a laser is provided, by which the desired intersection area can be projected to the three-dimensional surface of the patient's body on the basis of the provided coordinates, while at least one laser beam generated by the laser can be guided along the contour of the desired intersection area sufficiently rapidly, so that the impression of a closed contour around the desired intersection area results. | 10-08-2009 |
