摘要： The present invention relates to monitoring motion in diagnostic imaging or radiation therapy. In order to improve workflow, a device is proposed that comprises an input unit, a processing unit, and an output unit. The input unit is configured to receive an electroencephalogram (EEG) signal measured from a patient. The processing unit is configured to determine a readiness potential (RP) based on the received EEG signal, to determine whether patient motion is likely to happen based on the received EEG signal, and to provide a control signal via the output unit as output, if it is predicted that patient motion is likely to happen. The control signal is usable for controlling an apparatus to perform a function to reduce motion artefacts during the medical imaging or to assure that radiation dose is delivered according to a planned dose map during the radiation therapy.
