Patents in the USA
US Patent US5823958A
A system and method including a transparent display positioned between an object and an observer on which displays a superimposed data image transformed from structural data by calculating the parameters of a three dimensional matrix with information collected from position sensors. The mathematical parameters of the three dimensional matrix are defined in order to transform the structural image data into the perspective display data. Once the parameters of the three dimensional matrix are established, any points of the structural image can be shown on the display as a virtual image corresponding to the points on the object in real time.
US Patent US5704897A
An apparatus and method enables a precise superimposition of an optical representation with a data field to support the navigation during endoscopic operations. An optical representation is acquired by an endoscope with a camera and displayed on a screen. A sensor is attached to the endoscope or camera to continuously detect its spacial position. A spacial data field is also acquired, from such techniques as X-ray tomography, NMR tomography or ultrasound, and allocated to a body in a certain position. A sensor which is adapted to be attached to the body compensates for any movement of the body. A computer is provided for registering selected points of the data field with respective points of the optical representation by displacement certain points of the data field while superimposed on the optical representation.
US Patent US5842858A
The jaw of a person and a model thereof is represented with a series of steps. A device for positional determination, which has marking points, is inserted into the oral cavity of the person, at least one picture of the jaw of the person is taken with an imaging process, such as X-ray, CT, MRI or the like, including the marking points in the picture. The picture is stored as a data set and the marking points are identified. After an impression is taken of the jaw, a model is created. The representation itself includes the following steps: a further 3D sensor is brought to the model of the jaw. Next, the device for positional determination is reinserted into the model of the jaw in the same position as when the picture was taken. The positional relationship is determined between a 3D sensor on the device and the 3D sensor on the model of the jaw. After the device has been removed, a further 3D sensor is brought to the model of the jaw and inserted in the same position as when the picture was taken. Then the positional relationship is determined between the 3D sensor of the device and the 3D sensor on the model of the jaw. An optical image and the data set are superimposed in the positionally correct relationship, or alternatively, an optical image of the model of the jaw and the data set as superimposed in positionally correct association.
US Patent US5678546A
The invention relates to a method for displaying moveable bodies, in which an optical representation of the body and a data field attributed to this body are displayed simultaneously or alternately from the same perspective and on the same scale in real time. The method includes the following steps: providing the optical image-reproduction system comprising a camera and a monitor; allocating a 3D – data field to the body having a certain position; continuously recording of the 3D – position of the body; continuously calculating of a display of the data field equivalent to the body’s momentary position; simultaneously or alternately representing the optical image and the data field on the monitor. An apparatus for carrying out this method is also provided.
