  • Publication number: 20220061783
    Abstract: Rapid and precise recording of a VOI is provided while monitoring a robot-assisted movement of a medical object through a hollow organ of a patient. For actuating an x-ray device that has a recording system, a user input for the recording of a recording region is accepted. A previously recorded three-dimensional volume image of at least part of the body, in particular of the hollow organ is provided. A length of travel covered by the object from measurement data and/or control data of the robotic system is ascertained. The current position of the object is ascertained on the basis of the three-dimensional volume image making use of the ascertained length of travel covered and a starting position of the object. The recording system of the imaging device is moved for isocentering and/or superimposing the recording region about the current position of the object. An image of the recording region is recorded.

  • Publication number: 20210338346
    Abstract: A method for automatically monitoring a robot-assisted movement of a medical object through a hollow organ of a medical object of a patient performed by a robotic system is provided. The method includes tracking movement of the medical object using a medical imaging device such that the medical object and/or the hollow organ is at least partially arranged in a recording region that is mappable by the imaging device. The tracking is effected by a relative movement between the recording system of the imaging device and the patient. An image of the recording region is recorded during the tracking. In each case, a further image is recorded at regular intervals. The current image in each case and/or sensor data from a sensor assigned to the robotic system or the object is evaluated to determine whether a situation relevant to decision-making and/or safety with respect to the robotic system is present.
