Magnetic resonance method and apparatus with display of data acquisition progress for a subject continuously moving through the apparatus
Abstract:
In a method and magnetic resonance apparatus to display progress of the acquisition of measurement data of an examination region of an examination subject during continuous travel of the examination region through a magnetic resonance apparatus, a current projection image is calculated on the basis of current measurement data acquired from central k-space during the continuous travel of the examination region, and the currently calculated projection image is displayed. By the calculation of the projection images on the basis of measurement data from central k-space, this calculation can ensue particularly quickly and with little effort. A particularly fast display of the projection images is therefore possible. A projection image can be calculated particularly quickly and simply from measurement data along a central k-space line—i.e. a k-space line that runs through the center of k-space—using a one-dimensional Fourier transformation along this central k-space line.
