We present a new computed tomography (CT) method for inverting the Radon transform in 2D. The idea relies on the geometry of the flat torus, hence we call the new method Torus CT. We prove new inversion formulas for integrable functions, solve a minimization problem associated to Tikhonov regularization in Sobolev spaces and prove that the solution ...

Ultrasound Computed Tomography

, 2022
This chapter presents theoretical, numerical, and experimental frameworks for the use of Ultrasound Computed Tomography (USCT) for cortical bone tissue imaging. Most of the research conducted on this topic concerns adult bone, although some work presented in this chapter is specific to the study of child bone.

Computed tomography of the heart [PDF]

American Journal of Roentgenology, 1976
In an attempt to evaluate the possible usefulness of transmission computed tomography, CT scans of the chest of a series of dead dogs were obtained by means of an EMI body scanner. The sections thus obtained with and without the injection of contrast material reveal a great deal of cardiac morphology.
