Abstract
In multisection magnetic resonance imaging, gradient strength and earliest desired echo time (TE) set a limit to the thinnest section achievable. Offset radio-frequency irradiation techniques and phase encoding within a thick section make possible the production of thin sections of clinically useful quality in practical imaging times.
摘要
在多层面磁共振成像中，梯度强度和最早期望回波时间（TE）为可实现的最薄层厚设定了限制。厚层内的偏移射频照射技术和相位编码使得在实际成像时间内产生具有临床实用质量的薄层成为可能。
