Abstract: A method for improved precision of irradiation in radiation therapy includes providing feedback to a patient with respect to the patient's respiration during the radiation therapy, wherein information about the patient's current respiratory state and/or instructions for action relating to the patient's respiration are communicated to the patient by means of ambient signals. Also described herein is a device for applying such a method.

Abstract: A patient validation method before a medical treatment, in particular before performing radiation therapy, is configured such that patient-specific data are recorded and saved in a validation database as reference features, wherein current patient features are ascertained and compared with the reference features before each treatment, and the reference features are updated to adapt to reality as needed, and wherein a release for treatment only happens when the comparison produces a preferably specifiable degree of correspondence.
