In a method for virtual adaptation of an object to be medically inserted in a patient, to a body part of the patient, the object is shown in a desired view on a monitor, the body part is shown in 3D on the monitor, the body part in its unchanged 3D-imaging context, is automatically displaced relative to the object until the object is adapted to the body part with the orientation of the object relative to the monitor remaining unchanged.

In a system for the producing and displaying a virtual access channel in medical images, having a computer with a monitor, and a position and orientation-capturing operating unit and a method for producing and displaying such a virtual access channel in medical 3D images, the computer contains a preoperatively obtained 3D data record of a patient to be examined and can display this as a 3D image and is connected with the operating unit such that a virtual optical channel of the 3D data record is excised from the data record based on a registration between the operating unit and the data record as well as based on different channel parameters, and is displayed on the monitor of the computer.

System and method for the creation of a virtual observation and access channel in medical 3D images

In a method for expanding the display of a volume image of an object region, in particular in medical applications, in which at least one first image data set of a larger object region is made available, at least one second image data set of a smaller object region is acquired, the smaller object region lying within the larger object region, and the first 3D image data set is brought into registration with the second 3D image data set. A synthesized 3D image data set is generated from the first and second 3D image data sets and visualized in a display. The first 3D image data in the first 3D image data set represent the smaller object region, if necessary after a suitable adaptation of the first and/or of the second 3D image data set, are replaced by second 3D image data of the second 3D image data set with identical scaling and alignment of the image data sets. An overview of the larger object region thus is possible, and the smaller object region of interest the image can be represented with up-to-date data as well as a higher resolution and/or a higher contrast.

Method for expanding the display of a volume image of an object region

In a method to extend the display range of 2D image recordings of an object region, particularly in medical applications, first 2D or 3D image data are acquired from a larger object region, and at least one additional set for 2D image data of a smaller object region is acquired that lies within the larger object region The first 2D or 3D image data are brought into registration with the additional 2D image data with a projection geometry. From the first 2D or 3D image data, an image data set is generated for an image display of the first object region, which is suitable for combination with the additional 2D image data. In the image display of the larger object region, at least temporarily, at least one display of the additional 2D image data is integrated, by image data in the first image data set, for the image display of the larger object region, being replaced with image data from the additional 2D image data representing the smaller image region. An overview of the larger object region is thus enabled, with the smaller object region of interest being displayed within the image in a more up-to-date fashion, as well as with higher resolution and/or higher contrast.

In a method and medical device for determining the coordinates of images of marks in a volume dataset, the marks are disposed on the surface of a subject, and the volume dataset represents the images of the marks and an image of at least the part of the subject on whose surface the marks are disposed. A data processing system stores the volume dataset. The volume dataset is picked up by a first imaging medical device and represents an image of at least a part of the subject on whose surface several marks disposed and images of the marks. With a navigation system, a relation of the coordinates of the volume dataset to the coordinates of the subject is provided in the form of a coordinate transformation during a registration.

In a system, method and workstation, images of a first subject are acquired with an image signal acquisition unit, the position of the image signal acquisition unit is determined, the position of a second subject is determined and the position of the second subject relative to the image signal acquisition unit is also determined and an image of the second subject is mixed into an image of the first subject acquired with the image signal acquisition unit.

A medical technical system computing unit for calculating a multi-dimensional image dataset from subject signals supplied to the computing unit and obtained from the examination of a subject with at least one pre-operative imaging method. A virtual, multi-dimensional image that can be calculated from the multi-dimensional image dataset via the computing unit can be displayed on a display unit. A controllable window can be displayed at the display unit via a window generator allocated to the computing unit. The image at the display means corresponding to a virtual location of the controllable window controllable is produced via a control unit allocated to the computing unit.

Medical-technical system

In a navigation system and method, sensors at location-invariant points are used to define a coordinate system serves for identifying the motion of an organ. An image of the organ can be registered in parallel therewith, by selection of a point whose path in the coordinate system is identified and displayed, for which purpose the image plane attitude is also identified and displayed by acquisition of a further sensor. Alternatively, a sensor can be attached to the organ, this position thereof being identified and the motion path being determined therefrom. A sensor located at an instrument is acquired in parallel therewith. The position of the instrument in the coordinate system is identified and displayed. The instrument can be manually or automatically moved.
