Embodiment Construction

[0023] The method of the invention is again explained in detail using the example of an operation (for example after a pelvic fracture) in which a mobile C-shaped device is used to record and display further 2D images of the treatment area during the operation.

[0024] Currently, a plurality of 3D image data sets which are generated prior to the intervention, for example from CT stereo recordings, are generally used for the planning and carrying out of the surgery. Visualization of the first 3D image data gives a complete, relatively large overview of the entire relevant body region. During the operation, however, the doctor must be supported by current imaging for various reasons, which is achieved, for example, by means of an endoscope, fluoroscopy or single-frame x-rays. In this way, the doctor can also directly track the changes for further image acquisitions that are repeated during the operation. The current imaging must be performed for safety reasons, since changes i...

Abstract

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.

Description

technical field [0001] The invention relates to a method for enlarging the display range of a two-dimensional image of an object area, wherein a first 2D or 3D image data of a larger object area is provided and at least one further 2D image of a smaller object area is recorded , the smaller object area is located within the larger object area, and the provided image data is combined with the 2D image for display. Background technique [0002] Currently, compact imaging systems such as mobile X-ray devices, ultrasound devices or endoscopes / laparoscopes are commonly used in surgical interventions. But these modules provide only a very limited field of view for visualization. It is desirable for surgeons to see local conditions within the treatment area on a larger scale as well. [0003] Various possibilities are currently known for recording 3D image data of the body over a relatively long time interval prior to a surgical intervention, for example using computer tomography...
