What is FFT Full Form in Medical?

The FFT full form in medical is Fast Fourier Transformation. In Medicine, Fast Fourier Transform techniques would imply algorithms that will be used in any signal analysis or processing by converting the signals from the time domain to the frequency domain. FFT Techniques usually can be found in medical areas like medical imaging and electrocardiography or ECG, electroencephalography, EEG, and further diagnostic technologies. Thus FFT makes it possible for extracting useful information from these complex biological signals, thus improving diagnostic and monitoring efforts.

Applications of FFT in medicine:

The FFT is predominantly used for the analysis of complicated signals possessing several frequency components. For instance, in medical imaging, FFT is employed to process the raw data through reconstruction of images merging frequency domain data in Magnetic Resonance Imaging or Computed Tomography. In electrocardiograms or electroencephalograms, the FFT aids in isolating certain known frequency parts from the electrical signals produced by the heart or brain, thus assisting in the diagnosis of maladies such as arrhythmias or epilepsy.

Implementation of FFT:

There are different methods to implement FFT. One among them is the Cooley-Tukey algorithm which is the most widely employed algorithm. It finds an efficient way of computing DFT by recursively decomposing the signal into smaller pieces. This can therefore quickly be reduced in calculating the number of calculations needed. Being powerful and efficient, FFT can find application in several fields including telecommunications, acoustics, medical diagnosis, and data analysis.
