    • 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).
    • 一种用于在可能产生显着水平的声学噪声的医疗扫描仪中进行医学扫描期间减轻患者焦虑的系统和方法。 处理器或控制单元(CU)在医疗扫描期间接收扫描仪噪声(SN)的参数中的变化量(ESN)的度量,例如, 基于实际扫描类型的扫描仪噪声水平估计。 然后,处理器根据变化的度量(ESN)向扫描期间向患者呈现音频视频风景(A,V)的音频和视频播放单元(AS,VS)产生输出(A1,V1) )在扫描仪噪声(SN)的参数中。 图像对象,例如 视频图像(V)中的运动图像对象被链接到音频信号(A),以便将患者的注意力从扫描仪噪声(SN)分散。 音频视频风景(A,V)可以根据估计的扫描仪噪声电平(例如, 两个不同场景之间的切换:一个用于嘈杂的扫描周期,另一个用于静默时段。 利用远低于扫描仪噪声(SN)的有限音频信号(A)电平获得患者的有效分心。
