摘要： The invention relates to a method of MR imaging of at least a portion of a body (110) of a patient placed in an examination volume of a MR device, the method comprising the steps of:—subjecting the portion of the body (110) to an imaging sequence comprising at least one RF pulse, the RF pulse being transmitted toward the portion of the body (110) via a RF coil arrangement (109) to which RF signals are supplied by two or more RF power amplifiers the RF power amplifiers being activated alternately during the imaging sequence in a time-multiplexed fashion, wherein the imaging sequence requires a RF duty cycle and/or a RF pulse duration exceeding the specification of at least one of the RF power amplifiers;—acquiring MR signals from the portion of the body (110); and—reconstructing a MR image from the acquired MR signals. Moreover, the invention relates to a method of MR spectroscopy involving the alternating use of RF power amplifiers in a time-multiplexed fashion.

摘要： The invention provides for a magnetic resonance imaging system (100) comprising: a magnet (104) for generating a main magnetic field with an imaging zone (110), and a gradient coil system (110, 112). The gradient coil system comprises a set of unshielded gradient coils (110). The magnetic resonance imaging system further comprises a processor (130) for controlling the magnetic resonance imaging system. Execution of the instructions stored in a memory cause the processor to: acquire (200, 304) imaging magnetic resonance data (152) from a volume (109) within the imaging zone using a zero echo time pulse sequence; reconstruct (202, 306) a three-dimensional image (156) using the imaging magnetic resonance data; subtract a calibration image from the three-dimensional image, the calibration image having been acquired without a subject in the imaging zone; and render the three-dimensional image on a display by projecting it on a two-dimensional plane.

摘要： The invention relates to a method of MR imaging of an object positioned in an examination volume of a MR device (1).It is an object of the invention to enable 'silent' ZTE imaging with sampling of k-space center. According to the invention, the object (10) is subjected to an imaging sequence of RF pulses (20) and switched magnetic field gradients (G), wherein an initial RF pulse (20) is radiated before setting a readout magnetic field gradient (G). An initial MR signal is acquired with the readout magnetic field gradient(G) ramping up after a delay after the initial RF pulse (20). Thereafter, the magnetic field gradient (G) remains switched on and the readout direction is gradually varied. Further RF pulses(22) are radiated in the presence of the readout magnetic field gradient(G) and further MR signal are acquired like in conventional ZTE imaging. Finally, a MR image is reconstructed from the acquired MR signals. Moreover, the invention relates to a MR device and to a computer program for a MR device.
