Cone beam computed tomography: A review
International Journal of Oral Health Dentistry, 2020 Successful management of endodontic problems is reliant on diagnostic imaging techniques to provide critical information about the teeth under investigation. CBCT is of great help in diagnosing conditions and diseases related to pulp and periapical tissue.

Journal of Applied Clinical Medical Physics, EarlyView.ABSTRACT Background In radiotherapy for early‐stage glottic cancer, evaluating the target surface dose at the glottic air–tissue boundary is crucial, as buildup effect can cause underdosing. The accuracy of dose evaluation in the surrounding tissues is affected by both the dose calculation algorithms and the accuracy of the Hounsfield unit values in ...

Identification of nonlinear beam-hardening effects in X-ray tomography [PDF]
arXiv, 2023 We study streaking artifacts caused by beam-hardening effects in X-ray computed tomography (CT). The effect is known to be nonlinear. We show that the nonlinearity can be recovered from the observed artifacts for strictly convex bodies. The result provides a theoretical support for removal of the artifacts.

Experimental Comparison of Efficient Tomography Schemes for a Six-Qubit State [PDF]
Phys. Rev. Lett. 113, 040503 (2014), 2014 Quantum state tomography suffers from the measurement effort increasing exponentially with the number of qubits. Here, we demonstrate permutationally invariant tomography for which, contrary to conventional tomography, all resources scale polynomially with the number of qubits both in terms of the measurement effort as well as the computational power ...
