Background
To determine the diagnostic role of CT added to ultrasound for the diagnosis of recurrent differentiated thyroid cancer (DTC) and to evaluate potential benefits for patients.
Methods
A total of 193 patients with recurrent DTC were retrospectively included. The diagnostic performances of ultrasound and combination of ultrasound and CT (ultrasound/CT) in detecting recurrence were compared...
Electrical capacitance tomography (ECT) is a noninvasive imaging reconstruction technique to visualize cross-sectional permittivity distribution of dielectric objects inside a domain, which is based on the measured capacitance on the electrodes mounted on the periphery. Numerous iterative image reconstruction methods have been developed to accelerate convergence rate and to enhance the quality of...
In general, image reconstruction algorithms for electrical capacitance tomography (ECT) can be classified into iterative and noniterative algorithms. Iterative algorithms produce better quality images however they can only be used off-line due to intensive computational burden. In the context of computational burden, in this paper we propose a fast noniterative image reconstruction algorithm called...
