Question

Quizplus · Accepted Answer

Fast Fourier Transformation (FFT) is the most widely used technique for MR image reconstruction. It is a mathematical algorithm that can convert time domain signals (raw data) into frequency domain signals (image). The raw data acquired during MRI scanning is in the form of k-space data, which is a 2D matrix. The FFT algorithm is applied to the k-space data to generate the final MR image. It is preferred over back projection and interpolation techniques as it produces high-quality images with a high signal-to-noise ratio and short reconstruction time. Larmor equation precession (LEP) is not a commonly used technique for MR image reconstruction.
