Fast Calculation of T2 Relaxation Time in Magnetic Resonance Imaging
Original language description
The main parameters displayed by means of magnetic resonance include, for example, relaxation times T1 and T2 or diffusion parameters. This paper presents the computation of relaxation time T2 measured indirectly with the Spin Echo method. The sensing coil of the tomograph provides a signal in which the important factor is the location of the peaks from individual measurements. These points must be interleaved with an exponential function. The relaxation time T2 can be directly determined from the exponential shape. The described process has to be repeated for each pixel of the sensed tissue, and this requirement makes the processing of larger images very demanding in terms of both the actual computation and the time needed for the entire operation. More concretely, if we assume the common resolution of 256x256, 20 slices, and five measurements with different times TE, it is necessary to reconstruct 1.3x106 exponential functions in total, which requires the processing of more than 6 MB
