Computer-Generated Index for Evaluation of Idiopathic Scoliosis in Digital Chest Images: A Comparison with Digital MeasurementJournal of Digital Imaging - Tập 21 - Trang 113-120 - 2007
Fuk-hay Tang, Lawrence W. C. Chan, Hin-pong Lau, Po-yan Tsui, Chi-wa Cheung
An intelligence system was used to generate index for scoliosis. Tests were designed to evaluate the consistency of the automatic computer-generated index and to quantify the correlation between Cobb angle and computer generated scoliosis classification index (SCI). A fully automatic computer-generated index can be used to assess the extent of spinal curvature rather than manual measurement on rad...... hiện toàn bộ
Proposal of a Quality-Index or Metric for Soft Copy Display Systems: Contrast Sensitivity StudyJournal of Digital Imaging - Tập 16 - Trang 185-202 - 2003
Jihong Wang, Ken Compton, Qi Peng
In addition to the inherent qualities of a digital image, the qualities of the monitor and graphics control card as well as the viewing conditions will affect the perceived quality of an image that is displayed on a soft copy display (SD) system. With the implementation of picture archiving and communication systems (PACS), many diagnoses are being made based on images displayed on SD devices, and...... hiện toàn bộ
Ultra-Low-Dose Spectral CT Based on a Multi-level Wavelet Convolutional Neural NetworkJournal of Digital Imaging - Tập 34 - Trang 1359-1375 - 2021

Spectral computed tomography (CT) based on a photon-counting detector (PCD) is a promising technique with the potential to improve lesion detection, tissue characterization, and material decomposition. PCD-based scanners have several technical issues including operation in the step-and-scan mode and long data acquisition time. One straightforward solution to these issues is to reduce the number of...... hiện toàn bộ
