NettetIn some cases, the ranges of the scanning angles are less than 180 ∘ or 180 ∘ +fan, which are known as the limited-angle CT. The reasons for limited-angle scanning might be to reduce the scanning time and X-ray dose exposed to patients or physical constraints (e.g., the object is too large and the scanner can’t image all of the object ... Nettet1. mai 2024 · Limited-angle X-ray computed tomography (CT) reconstruction is a typical ill-posed problem. To recover satisfied reconstructed images with limited-angle CT … rosie house cleaning

Nettet6. jan. 2024 · Under some circumstances, in order to reduce the scan time, decrease the X-ray radiation or scan long objects, furthermore, to avoid the inconsistency of the detector for the large angle scanning, we use the limited-angle TCT scanning mode to scan an object within a limited angular range. Nettet31. mai 2024 · In this paper, we consider minimizing the L1/L2 term on the gradient for a limited-angle scanning problem in computed tomography (CT) reconstruction. We design a specific splitting framework for an unconstrained optimization model so that the alternating direction method of multipliers (ADMM) has guaranteed convergence under … Nettet7. apr. 2013 · This paper presents a compressed sensing (CS)-inspired reconstruction method for limited-angle computed tomography (CT).
