To reduce the likelihood of errors in organ delineations used for radiotherapy treatment planning, a knowledge-based quality control (KBQC) system, which discriminates between valid and anomalous delineations is developed.The KBQC is comprised of a g

The purpose of this study was to develop a novel algorithm to create a robust internal respiratory signal (IRS) for retrospective sorting of four-dimensional (4D) computed tomography (CT) images.The proposed algorithm combines information from the Fo

Improved three-dimensional Look-Locker acquisition scheme and angle map filtering procedure for T1 estimation

Autor: CheukKai, Hui, Emilio, Esparza-Coss, Ponnada A, Narayana

Publikováno v: NMR in biomedicine. 26(11)

The three-dimensional (3D) Look-Locker (LL) acquisition is a widely used fast and efficient T1 mapping method. However, the multi-shot approach of 3D LL acquisition can introduce reconstruction artifacts that result in intensity distortions. Traditio
