Abstract: A method and an apparatus for detecting an isolation pad in medical imaging, and a medical imaging system are provided. The method includes: acquiring an image of a detection object captured via a camera; determining, based on the image, whether an isolation pad is present at a predetermined part of the detection object; and outputting information related to a result of the determination. The present application detects an isolation pad placed on the body of a detection object, and it is thus possible to reliably avoid the formation of a loop in the body of the detection object.

Abstract: Spike noise in a k-space dataset acquired in magnetic resonance imaging may be removed by generating a mask including a set of data points which constitute spike noise in the k-space dataset based on the acquired k-space dataset via a trained deep learning network, the mask corresponding to a location of the spike noise in the acquired k-space dataset. An image reconstructed based on the acquired k-space dataset and the mask may be displayed.
