摘要：
A system and method for reducing anxiety of a patient during medical scanning in a medical scanner which may produce significant levels of acoustic noise. A processor or control unit (CU) receives a measure of variation (ESN) in a parameter of the scanner noise (SN) during the medical scanning, e.g. estimated scanner noise level based on the actual type of scanning. The processor then generates outputs (A1, V1) to audio and video playback units (AS, VS) that accordingly present an audio-video scenery (A, V) to the patient during the scanning, in accordance with the measure of variation (ESN) in the parameter of the scanner noise (SN). An image object, e.g. a moving image object, in the video imagery (V) is linked to the audio signal (A), so as to distract the patient's attention away from the scanner noise (SN). The audio-video scenery (A, V) may be switched according to an estimated scanner noise level, e.g. a switch between two different scenes: one for noisy scanning periods, and another one for silent periods. An effective distraction of the patient is obtained with a limited audio signal (A) level which is far lower than the scanner noise (SN).
