Abstract: A method for determining a trigger signal for an imaging device is based on receiving a film of a surface of a first body part of a patient. In an embodiment, image values in a region in the images of the film are averaged. The noise of the image values in the region is reduced by way of the averaging. The film is transformed into a temporal signal series on the basis of the averaging. The transformation takes place in such a manner that the temporal series is a measure of the timing pattern of the blood circulation in the area. Furthermore, the temporal signal series is analyzed to ascertain whether the temporal signal series satisfies a preset criterion. Finally, a trigger signal is determined for an imaging device if the temporal signal series satisfies the preset criterion.

Abstract: In a method to control a medical apparatus of an installation having: a contact device for a patient, at least one electrical potential sensor that can be coupled to the body of said patient is integrated into the contact device. A signal evaluation device is provided with measurement signals generated with the electrical potential sensor for evaluation. The medical apparatus is connected with the signal evaluation device, and measurement signals that relate to the breathing and/or cardiac activity of the patient are acquired with the at least one electrical potential sensor coupled to the body of said patient upon contact of the patient with the contact device. Trigger signals are generated with the signal evaluation device based on the measurement signals that relate to the breathing cycle and/or the cardiac cycle of the patient. Operation of the medical apparatus is controlled based on the trigger signals.

Abstract: A method for determining a time point of a heart movement is described, wherein an EKG signal showing the heart movement is received. A first time point is determined, after which a mechanical signal characterizing the heart movement will probably be received, as a function of the received EKG signal. A mechanical signal is also received after the determined first time point. The time point of a heart movement can be concluded based on the receive time point of the mechanical signal. An apparatus for determining a time point of a heart movement is also described. The apparatus has a first receive facility, a timing facility, a second receive facility, and an evaluation facility. The evaluation facility is configured to determine the receive time point of the mechanical signal and to determine a time point of a heart movement based on the determined receive time point of the mechanical signal.

Abstract: A method is used to determine motion of an examination region of a patient. It is based on the use of a flat antenna arrangement, including at least one transmit unit and several receive units, as well as on the use of the transmit unit actuated by a control signal for the transmission of radar signals in the direction of the examination region, and the use of receive units for the receipt of radar signals reflected by the examination region. The method further includes the read-out of receive signals from the receive units, with the receive signals corresponding to the radar signals received. The assignment of the radar signals received to the transmit unit which transmitted the radar signals received in each case, by correlating the receive signals to the control signal, advantageously makes possible the adjustment of parameters derived from the correlated receive signals to retrievably stored model data.

Abstract: A radar system, a medical diagnostic or therapeutic device and a method are disclosed for operating a radar system. An embodiment of the radar system includes an antenna arrangement embodied to be flat including individually actuatable transmit units for the transmission of radar signals and individually readable receive units for the receipt of radar signals. The transmit units and the receive units each include at least one antenna. Because the transmit units can be individually actuated and the receive units can be individually read out, the information content which can be obtained even without a strong spatial orientation of the radar beam, is increased. According to an embodiment of the invention, the radar system is designed to assign a radar signal received by a receive unit to the transmit unit which transmitted the radar signal received.

Abstract: An automatic syringe pump is disclosed that includes at least four subsystems: mechanical power, electronic timing, mechanical power transfer, and user interface subsystems. In some embodiments, an occlusion detection subsystem is also present. The mechanical power subsystem's main includes a constant force spring capable of storing the energy needed to reliable depressed several different sizes of a syringe. The electronic timing subsystem may include components including a ratchet, pawls, flippers, stepper motor, and microcontroller.
