Concept
Backprojection is a computational technique used in image reconstruction, particularly in computed tomography (CT) and other imaging modalities, to transform raw data into a visual format by projecting it back into image space. It is foundational in creating cross-sectional images from projection data, but it often requires additional filtering to enhance image quality and reduce artifacts.
Concept
Tomographic reconstruction is a computational technique used to create a 3D image from a series of 2D projections taken at different angles, commonly used in medical imaging and industrial applications. It involves solving an inverse problem to reconstruct the internal structure of an object, enabling non-invasive analysis and diagnostics.
