Tomographic reconstruction is a type of multidimensional technique used in image processing to create a 3D model of an object from a series of 2D images. This technique is commonly used in medical imaging technologies such as computed tomography (CT) and magnetic resonance imaging (MRI).

Overview[edit | edit source]

Tomographic reconstruction involves the process of obtaining a tomogram (a two-dimensional image of a slice through an object) via tomography. Tomography as a method is used in diverse fields such as radiology, archaeology, oceanography, astrophysics, quantum information, and materials science.

Process[edit | edit source]

The process of tomographic reconstruction involves several steps. First, a series of 2D images are taken around a single axis of rotation. These images are then used to reconstruct a 3D model of the object. This is achieved through a mathematical procedure known as the Radon transform and its inverse.

Applications[edit | edit source]

Tomographic reconstruction is widely used in medical imaging. It is a fundamental part of CT scans, which use X-rays to create detailed images of the body. It is also used in MRI scans, which use magnetic fields and radio waves to create images of the body. Other applications include electron tomography, seismic tomography, and optical tomography.

Challenges[edit | edit source]

Despite its wide applications, tomographic reconstruction faces several challenges. These include the need for a large number of images, the requirement for precise alignment of the images, and the computational complexity of the reconstruction process.
