摘要
A method and appertaining device is provided for magnetic resonance imaging of a contiguous region of a subject under application of the partially parallel acquisition via modulation of the spin magnetization by way of radio-frequency pulses, as well as via spatial coding of the subject region and via subsequent measurement in cycles of the radio-frequency response signals showing the excited spins. Based on the measurement of the radio-frequency response signals by a coil array comprising two or more radio-frequency receiver coils via which both the coil sensitivity information and the radio-frequency response signals are acquired, each radio-frequency receiver coil acquires a reduce data set for implementation of the image reconstruction and additional modulations of the spin magnetization are used; additional modulations are comprised of modulations of radio-frequency pulses and/or additional modulation of gradients used for spatial coding of the subject regions.
