The invention relates to a magnetic resonance imaging control method and device. The method comprises the following steps: presetting a scanning parameter and an image quality threshold for a quality control module based on an artificial neural network; inputting K space data of the current examination body into the quality control module; acquiring an image quality factor corresponding to the K space data; according to the image quality factor and the image quality threshold, judging whether the current examination body needs to be scanned again or not; and generating a re-scanning strategy when the current examination body is re-scanned. By adopting the method, whether re-scanning is needed or not and a re-scanning strategy is generated can be quickly judged according to the K space data under the condition of avoiding image reconstruction. 本申请涉及一种磁共振成像控制方法、装置。所述方法包括：对基于人工神经网络的质量控制模块预先设定扫描参数和图像质量阈值；向所述质量控制模块输入当前检查体的K空间数据；获取所述K空间数据对应的图像质量因子；根据所述图像质量因子与所述图像质量阈值，判断是否需要对所述当前检查体进行重新扫描；在所述当前检查体进行重新扫描时，生成重新扫描策略。采用
