Definitions

• the invention relates to a device for cross-platform and data-specific visualization of 3D data sets by means of visualization software for display on a 2D monitor.
• volume data must be exchanged among doctors and visualized on different computers.
• a program must be made available in addition to the medical data set, which allows the visualization of the 3D data on the 2D monitor.
• the use of different methods for volume visualization and the many options for parameterizing the algorithms lead to different image quality.
• volume data record was transmitted via a DICOM interface to a medical workstation on which expensive volume visualization software is installed, although difficulties can also arise here if these volume visualization software is not the same as that used on the radiologist's original computer.
• the invention is therefore based on the object of creating a device for cross-platform data-specific visualization of 3D data records which, with a simple structure, works independently of the computers used and any visualization software and thus enables 3D volume data records to be reproduced in the best possible quality can also be ordered and viewed by any third party.
• the 3D volume data is stored on a data carrier together with a visualization software and this is transmitted to a user for playback on any PC.
• the 3D volume can be visualized on any PC without any additional software installed on this PC.
• the unit of data set and visualization algorithm also ensures that it is not a general visualization tool with which any data set can be displayed.
• the visualization parameters are at least partially unchangeable. This results in the advantageous possibility of making a 3D volume data record created by a radiologist, in which certain structures have been particularly emphasized by special visualization parameters, available to the surgeon in the operating room, for example, in which case he then also sees exactly the structures that the radiologist has highlighted the visualization parameters in detail based on his specialist knowledge. In many cases, especially when transmitting such 3D data to less experienced doctors, it may be advisable not to leave them with all the options for selecting the various visualization parameters, since in most cases they are completely overwhelmed and ultimately none at all from the data bring out usable image.
• the problem of forwarding such 3D volume data sets to doctors can be solved in a simple manner so that the It is very simple to pass on the fact that the recipient does not need any special equipment (expensive visualization software on his workstation) and that the data of the 3D volume data set that is of interest to the recipient are reproduced in such a way that even a non-radiologist receives an optimal display.
• the surgeon still has the possibility to rotate the 3D volume data set, for example with particularly emphasized bone structures or vascular trees, in space and to view all possible points of view for the preparation of the operation with fixed visualization parameters.
• the volume of interest is irradiated by an optical center 1 and the points lying on the radiation line are imaged in an image plane.
• a 3D volume data record can be calculated from several two-dimensional images created by different optical centers 1 using an algorithm.
• the points lying on a projection beam 3 are added to the 3D volume V according to variable aspects, namely the so-called visualization parameters, for example with their gray values and as an image point on the 2D monitor 2 shown.
• the setting of the visualization parameters is a particularly difficult art that only experienced radiologists can master, while normal doctors can only very difficultly extract the structures they want from a 3D volume data set.
• vascular trees in the 3D volume V are particularly emphasized or certain bone structures or other medical details.
• these visualization parameters are recorded together with the respective visualization software and the 3D volume data by the radiologist creating the data, in particular burned to a CD, then this data carrier can be sent very easily to a doctor or another department of a hospital, where a simple PC for visualization is sufficient, which does not require any special installations for visualization at all, that is, in particular, on which no expensive visualization software needs to be installed.
• the simultaneous saving of the visualization parameters as far as possible in such a way that the recipient can no longer change them has the advantage that even less experienced doctors can view exactly the structures highlighted by the radiologist in best image quality on their simple PC.
• An example scenario could look like this:
• a neuroradiologist With an angiography system, a neuroradiologist generates a three-dimensional volume data record, edits the volume in such a way that an aneurism is clearly visible and burns a CD for the neurosurgeon. He takes the CD, plays it on a standard PC and can immediately visualize and analyze the SD data record. He does not need a special workstation, can inspect the data set on any computer and still with the same quality as his colleague from neuroradiology.
