A method for recording image data of a moving, (e.g., cyclically moving), region of interest of a patient by a medical imaging system with an X-ray source and an X-ray detector, wherein a robotic device with a kinematic chain of moving components has a tactile connection with the patient, and wherein, the tactile connection is maintained at least for a prespecified period. The method includes acquiring measured values by sensors of the robotic device, evaluating the measured values and forwarding to the medical imaging system, wherein the evaluated measured values include information on the movement and/or position of the region of interest, and irradiation of the region of interest by the radiation source and recording of image data of the irradiated region of interest by the X-ray detector, and wherein the evaluated measured values are used to actuate the imaging system.

Method for recording image data and medical imaging system

A method is provided for controlling a robotic device, of which the end effector arranged on a kinematic chain interacts with an object, and including an ultrasound apparatus registered to the robotic device for movement capture of the object. Ultrasound image data of the object is captured. The relative movement of the object is determined on the basis of the ultrasound image data using a mathematical method. The absolute movement is determined through registration to a planning data set. Movements of the object are compensated for in the context of the interaction of the end effector of the robotic device with the object. Future movements of the object and a positioning of the end effector of the robotic device adapted thereto are predicted and the robotic device is controlled accordingly. In the calculation of the adapted positioning of the end effector of the robotic device, a temporal delay relative to the movement of the object is included.

Control method for a robotic device with an ultrasound apparatus and robotic device

A method for calibrating a medical imaging device in terms of an image acquisition geometry, a method for performing a two-dimensional-three-dimensional registration based on corresponding calibration data, and a corresponding system are provided. Multiple images of a phantom are acquired using the imaging device in different positions of the phantom. A corresponding motion of the phantom from one position to a respective next position is tracked by a tracking device to keep continuous track of a spatial relation between the phantom and the imaging device. The medical imaging device is then calibrated based on the acquired images, corresponding recorded poses of the imaging device, and the tracked motion of the phantom.
