Reduction of radiation disturbances in heartbeat measurements

摘要

A method for heartbeat measurement (M-ECG) during irradiation of a patient (P) with ionizing radiation, comprising the steps of: - determining a position (PB (t)) of an irradiation area (BB), - identifying by the ionizing radiation influenced for determining a heartbeat signal from the patient (P) arranged heartbeat sensors (S (t)) in dependence on the determined position (PB (t)) and the extent (ASD) of the irradiation area (BB), - suppressing a heartbeat Signal disturbance on the basis of the knowledge of the ionizing radiation-influenced heartbeat sensors (S (t)) in a heartbeat measurement process (M-ECG).
