Fourier Transformation is a mathematical technique that transforms signals between time (or spatial) domain and frequency domain. This process is essential in analyzing waveforms and complex signals, allowing for a deeper understanding of their frequency components. In the context of medical imaging, Fourier Transformation plays a crucial role in reconstructing images from raw data collected during procedures like CT scans and MRIs, enabling the conversion of complex data into visual representations that can be interpreted by medical professionals.

By transforming data into the frequency domain, Fourier Transformation helps identify various characteristics of signals, including their frequency content, which is critical in solving linear differential equations and understanding waveforms. This analysis not only applies to visual data but can also be extended to various forms of signal processing, making it a fundamental tool within the field of medical imaging and technology.
