1. A system, comprising:
an imaging apparatus or a radiation therapy delivery apparatus;
at least one transmitter configured to generate from a distance an outgoing signal capable of impacting on a patient's skin, thereby causing a haptic sensation at an impact region on the patient's skin; and
a control logic circuit configured to modify the outgoing signal based on a distance between i) a current position of a region of interest of the patient and ii) a target area in the imaging apparatus or in the radiation therapy apparatus, wherein the control logic circuit is further configured to receive a measurement signal in relation to the patient and modify the outgoing signal based on the measurement signal, wherein the measurement signal represents a patient's vital sign, and wherein the outgoing signal is capable to urge the patient to move to a position such that the region of interest is or remains within the target area in order to achieve a correct patient positioning in an imaging procedure or radiation therapy.
