The present disclosure directs to a system and method for configuring a pulse sequence in MRI. The method may include obtaining a preliminary gradient pulse configuration, wherein the preliminary gradient pulse configuration relates to a portion of a pulse sequence to be implemented by one or more coils of an MR scanner, the pulse sequence including a plurality of gradient pulses. The method may also include determining a global peripheral nerve stimulation (PNS) value of the preliminary gradient pulse configuration according to a PNS model. The method may further include determining a target gradient pulse configuration based at least in part on the preliminary gradient pulse configuration, the global PNS value, and a PNS threshold.

Systems and methods for pulse sequence configuration in magnetic resonance imaging

A method for magnetic resonance imaging (MRI) may include cause, based on a pulse sequence, a magnetic resonance (MR) scanner to perform a scan on an object. The pulse sequence may include a steady-state sequence and an acquisition sequence that is different from the steady-state sequence. The steady-state sequence may correspond to a steady-state phase of the scan in which no MR data is acquired. The acquisition sequence may correspond to an acquisition phase of the scan in which MR data of the object is acquired. The method may also include generating one or more images of the object based on the MR data.

Systems and methods for magnetic resonance imaging

Systems and methods for generating an image of a subject using a magnetic resonance imaging (MRI) device may be provided. The method may include obtaining a radial sampling scheme including a plurality of radial lines that each pass through a center of k-space. The method may include selecting the plurality of radial lines of the radial sampling scheme. Each of the plurality of radial lines may be selected in a random and unrepeatable manner. The method may include acquiring k-space data along the selected radial lines. The method may include reconstructing at least one image of the subject based on the acquired k-space data.
