Magnetic resonance imaging method and device based on balanced steady state free precession sequence

A magnetic resonance (MR) imaging device, comprising:

• readout gradient determination circuitry configured to determine a readout gradient time profile including a climbing period, a platform period, and a descent period;
• analog-to-digital conversion (ADC) circuitry configured to collect k-space data upon being turned on;
• sequence execution circuitry for configured to perform a balanced steady state free precession sequence,
• wherein the readout gradient is applied in the readout direction, the analog-to-digital conversion circuitry is opened during the climbing period, the analog-to-digital conversion module is maintained in an on state during the platform period and turned off during the descent period;
• conversion module circuitry configured to convert the k-space data collected by the analog-to-digital conversion module into uniform k-space data;
• and
• image generation circuitry configured to generate a magnetic resonance image based on the uniform k-space data.

A computer-readable storage medium having instructions stored thereon that, when executed a processor identified with a magnetic resonance (MR) imaging device, cause the MR imaging device to:

• determine a readout gradient time profile including a climbing period, a platform period, and a descent period;
• perform a balanced steady state free precession sequence in which the readout gradient time profile is applied in a readout direction;
• activate analog-to-digital conversion (ADC) circuitry to collect k-space data during the climbing period, the analog-to-digital conversion circuitry being maintained in an on state during the platform period;
• deactivate the ADC circuitry during the descent period;
• convert the k-space data collected by the ADC circuitry to uniform k-space data;
• and
• generate an MR image based on the uniform k-space data.
