Problems solved by technology

[0004] Manual user interaction with the localization system or segmentation algorithm is disadvantageous because it interrupts the user's workflow, thereby distracting the user and also taking a corresponding amount of time
Furthermore, the interaction requires physical manipulation of the input device by the user, which is especially detrimental in a sterile environment

Embodiment Construction

[0089] figure 1 A schematic diagram of an exemplary embodiment of an apparatus 10 for automatic positioning of structures according to an improved design is shown in .

[0090] The device 10 has a computing unit 13 and a display device 11 (eg a monitor with a display surface 12 ).

[0091] The device 10 has, for example, an imaging device 22 which is in figure 1 The example of is designed as an x-ray device, for example as a C-arm x-ray device, by way of example but not limitation.

[0092] In this example, the imaging device 22 has an x-ray source 23 as well as an x-ray detector 24 and a support surface 26 on which an object 27 (for example a person) can be arranged. The x-ray source 23 emits x-rays, which at least partially pass through the object 27 and are correspondingly picked up by the x-ray detector 24 .

[0093] The x-ray detector 24 is connected to the computing unit 13 , in particular to the x-ray image processor 14 of the computing unit 13 , in order to transmit...

Abstract

According to a computer-implemented method for automatically positioning a structure (9), a single image (17) mapping an object having the structure (9) is displayed on a display surface (12). A gazemovement of a user (19) is detected by means of a gaze detection system (18), and a gaze detection signal is generated on the basis of the gaze movement. At least one image point (20) of the single image (17), which at least partially maps the structure (9), is identified by means of a computing unit (13) on the basis of the gaze acquisition signal.

Description

technical field [0001] The invention relates to a computer-implemented method for automatic positioning of a structure, wherein a single image mapping an object having the structure is displayed on a display surface. Furthermore, the invention relates to a device for automatic positioning of structures, a computer-implemented method for training a software module, and a computer program. Background technique [0002] In various applications in which objects are analyzed or manipulated by humans in an image-supported manner, for example in the field of medical applications, the correct determination of the position of structures in the image data is of decisive importance for further method steps. In medicine, this is the case, for example, for analytical or diagnostic methods or for interventions assisted by imaging methods such as fluoroscopy-based methods. Especially for many medical applications, correct segmentation of anatomical objects is decisive for further treatmen...
