Problems solved by technology

For example, it is very inconvenient for the doctor to look away from the surgical field to analyze the X-ray images displayed on a separate monitor
[0006] Concrete systems are currently lacking in medical technology which combine and spatially resolved fusion of graphical surface information in three-dimensional form and graphical depth information of body segments in a suitable manner

Embodiment Construction

[0053] The present invention is explained in detail below with reference to the accompanying drawings.

[0054] figure 1 A visualization system, which is used in particular during medical interventions, is shown in a schematic manner. This can be surgery or image data acquisition for planning further steps or other measures. The visualization system is used to visualize or display the three-dimensional patient structure in space. In this case, both a three-dimensional image of the body surface is to be acquired in a preselectable region (region of interest—ROI) and the image acquired with imaging device 10 is also to be displayed. The imaging device is in particular a mobile C-arm which is mobile and can be placed on a trolley 18 , for example. The C-arm is used to acquire X-ray images and / or tomosynthesis images. Of course, the invention can also be applied to other imaging modalities, such as magnetic resonance tomography equipment. However, the following description of...

Abstract

The invention relates to an intraoperative, marker-free visualization system and method for visualization of three-dimensional surface structures and deep structures of a patient within the scope of interventional procedures. A C-arm (10) with a C-arm projection module (16) and a camera (14) and visualization glasses (20) with an HMD projection module (22) and a camera (24) are provided for this purpose. Projection modules (16, 22) are used to project structured light. The processor (25) is configured to calculate a combined image data set (kBD) for projection onto the spectacle lens (21) of the visualization glasses (20).

Description

technical field [0001] The present invention relates to surgery for visualizing medical structures (such as bones, organs or implants) in and thus "deep" in a patient's body, and for visualizing superficial structures on the body surface, in particular by means of X-ray-based methods In the field of visualization technology. The invention can preferably be applied to interventions in surgery. Background technique [0002] Navigation systems are known in the prior art in order to be able to guide a doctor in a targeted manner in space when carrying out medical interventions. For this purpose, however, other modules must be provided in addition to the imaging device, which are required within the scope of the navigation system. This involves in particular providing a separate camera with a corresponding power cord and network connection cord. However, these power and network connections can disadvantageously limit the mobility of the doctor during the intervention and often...
