Original sentence: However, Damadian's scanner neither included the fundamental concept of a frequency-encoding magnetic field gradient, which encodes the one-dimensional intensity projection of an object in such a way that it may be recovered by a simple Fourier transformation, nor did he describe a technique for true two-dimensional imaging.Instead, Damadian's idea of a scanner was designed to map an object sequentially point by point.MR scanners currently used in medical and non-medical practice all rely on the gradient imaging technology first published by Paul Lauterbur in his 1973 paper, and they use the tissue signals that Damadian discovered to create the needed contrast in the image.While Damadian's scanner did not include the fundamental concept of a frequency-encoding magnetic field gradient, , which encodes the one-dimensional intensity projection of an object in such a way that it may be recovered by a simple Fourier transformation, his original conception of a whole-body NMR scanner and discovery of the T1 and T2 signal differences between normal tissues and cancer tissues, as well as among the different tissues of the body, are foundational to the development of the MRI
