Scoutless whole-body imaging with fast positioning |
摘要 |
A method and apparatus are provided for forming a magnetic resonance angiographic image of a human body. A plurality of spatially non-selective radio-frequency pulses and a plurality of different combinations of phase-encoding gradients are applied to the human body, that are temporally non-coincident with the radio-frequency pulses and where each combination includes a pulse value in a slice selective direction and a pulse value in an in-plane direction and magnetic resonance imaging data are detected. A slice processor and/or a thickness processor identify the presence, location and/or thickness of a body portion of the human body. Identification of a body portion in a first imaging volume becomes the basis of application of a second plurality of spatially non-selective radio-frequency pulses to a second imaging volume of the human body.
