Computed Tomograph (CT) is a medical imaginag technique that uses X- ray measurements taken from different angles to create detailed cross-sectional images of thee body. Understanding thee fyzics behind CT enterves grasping thee key calculations that enable exaccerate image rekonstruktion.

Základní zásady pro CT Fyzika

CT imagg relies on t e attenuation of X- ray beams as they pas protingh tissues. Thee decepe of attenuation varies with tissue density and composition. Detectors measure the transmitted X- ray intensities, which are then used to rekonstrukt images.

Key Calculations in Image Reconstruction

Te primary access in CT is the Radon transform, which converts those measured projections into a form suable for image rekonstruktion. Te inverse Radon transform, often implemented via filtered back projection, is used to generate te te cross- sectional imases.
