An automatic fMRI protocol for the investigation of the human auditory cortex has been developed. For the activation of the auditory system, the scanner noise itself is the source of sound. Rapid switching of B0 gradients allows the generation of tones of defined frequencies and amplitude on a conventional scanner without hardware change. No additional device for sound generation or sound delivery is needed. The proposed technique allows functional MRI of the auditory cortex in a clinical routine session.
一种用于研究人类听觉皮层的自动功能磁共振成像（fMRI）方案已被开发出来。为了激活听觉系统，扫描仪噪声本身就是声音来源。B0梯度的快速切换使得在无需硬件改变的传统扫描仪上能够生成特定频率和振幅的音调。无需额外的声音生成或声音传输设备。所提出的技术允许在临床常规检查中对听觉皮层进行功能磁共振成像。
