- segmentation In the medical image processing of volume data (ie three-dimensional data), the segmentation of body regions or anatomical structures represents an essential processing step. Segmentation hereby means the identification and detachment of the corresponding body regions and anatomical structures from their surroundings. The Segments mentation serves in particular for better visualization, orientation, measurement, navigation (in volume), comparability of results and the like. In the context of the evaluation, it is often necessary to prepare the segmentation specifically for the intended application. This step is often very complex and often consists of often repetitive processes.
- the preparation often takes place in such a way that the computer first of all outputs the volume data record - possibly already partly processed - to the user via the viewing device.
- the user selects a portion of the volume data set (for example, by setting a seed point ⁇ ), gives the computer an object type before and abuts a segmentation.
- the computer then segments an object and assigns the specified object type to the segmented object.
- the computer assigns - automatically or according to a specification by the user - the segmented object to one of many predefined application rules.
- the predefined application requirements often comprise respective display parameters affecting the nature of depicting ⁇ lung of objects of each object type in the picture.
- the computer takes into account the respective display parameters when determining the mapping of the objects of the respective object type.

- the computer accepts from the user the first selection command counter and selected on the basis ofassibe ⁇ tivs the corresponding group provision. Due to the se ⁇ lected group provision the computer knows which objects should be present in the volume data set. The computer can automatically menting for the ent ⁇ preserved in the selected group provision object types in the volume data set or with the support by the user the associated objects segmental therefore, starting from the selected group rule. As a result, in many cases almost the entire preparation of the volume data set can be automated.
- the computer checks whether at least one object is segmented in each case for all object types contained in the selected group instruction in the volume data record. In this case, the computer will give a message to the user if this is not the case. This allows the computer to alert the user to deviations from the standard case, according to which - according to the selected group rule - all corresponding objects should be present in the volume data set. It can - depending on the individual case - be sensible to cancel more Bear ⁇ processing the volume data set, if not jekttypen for all included in the selected group provision Obwalden in the volume data set at least one object is segmented. Alternatively, it may be useful to make the Mel ⁇ dung only as a warning, so that the loading Although the user is made aware of the deviation from the normal case, this can be ignored if necessary.
- the application instructions often include display parameters.
- Display parameters are often very complex. They assign each gray value in the three-dimensional volume of a certain color, transparency, contrast, lighting, sharpness and the like.
- the presentation parameters affect the way in which objects of the corresponding object type are displayed in the image output to the user.
- the representation of parameters define mostly curves (ramps, trapezoids, freehand definition, and others), due to which then a respective gray scale value of each ⁇ minister object ness a respective color, transparency, brightness, etc. is assigned.

- Two objects can be in the same location in the image, even though they are in different locations in the three-dimensional volume, but the image is a two-dimensional image.
- Two objects can occupy the same place in three ⁇ dimensional volume, such as when multiple volume data sets are superimposed.
- Such an overlay may be useful, in particular, if the volume data records show the same examination object from the point of view, but a temporal development of the examination subject has taken place.

- the creation of the group regulations Gi and also of the application instructions Aj can take place as required. It is for example possible that the corresponding rules Gi, Aj, A 'are fixed to the computer 1 and the user 5 can not be changed. Preferably, however, the computer 1 is in the context of the processing of the machine code 4 able to move into an editing mode. Of the
- Edit mode is executed by the computer 1 before or after execution of a machining method, as explained above in connection with FIGS. 1 to 7.

- the application procedure Aj or supplemental prescription A ' can - but need not - be ⁇ already part of a group provision Gi.
- step S44 of the computer 1 the computer 1 processes a group instruction Gi. If necessary, the processing can be done by creating a new group rule Gi, possibly deleting an existing group rule Gi, adding an additional, but already existing application rule Aj to the group rule Gi, possibly removing an already existing application rule Aj from the group rule Gi or switching an existing group rule Gi between the states and be disabled. If it is at the machining ⁇ processing command C3 is a command to edit a group Gi procedure, thus the corresponding groups Gi ⁇ prescribed by means of the edit command C3 required are switched created, modified, extended or ak ⁇ tivated between the states / deactivated.
