Question

Data produced by one kind of this technology is stored by the NIfTI (“nifty”) file format, which was created to improve on the lack of orientation in the Analyze 7.5 format. At low SNR, the distribution of data produced by this technology is biased due to noise that has a Rician (“RICE-ian”) distribution, instead of the Gaussian noise at higher SNR. In this technology, applying frequency and phase encoding gradients gives spatial data that is stored in a k-space matrix, which is then Fourier-transformed to produce the output. Classes of pulse sequences programmed into this technology’s machines include (*) inversion recovery and spin echo. (10[1])RF coils (10[1])are used in this technology to receive signals from excited atoms, typically hydrogen due to its abundance in the body. For 10 points, (10[1])name this medical technology, whose control room computers must be shielded because it uses very strong magnetic (10[1])fields. ■END■ (10[1])
