Appliing Fourier Analysis zw Ct Skanery
Fourier analysis is a mathematical technique used to transform signals between time or spatial domains andd frequency domains. In medical maing, specilarly in computid tomography (CT), this methods plays a ccial role in improwing imes quality and reconstruction closacy.
Basics of Fourier Analysis in CT Imabing
In CT scans, X- ray data is collected from multiple angles around the body. Fourier analysis helps convert this raw data into frequency contents, enabling more efficient image reconstruction. This process simplifies the complex data, making it easyr to interpret and process.
Enhancing Image Reconstruction
Inflying Fourier transformas allows for filtering and noise reduction in thee frequency domayn. Thies improwises the e clarity of thee reconstructed images, making it easyr to identify inoralities. Techniques such as filtered back projection rely heavily on Fourier analysis to produce exate images.
