The strategic and operational characteristics of a distributed phased archive for a multivendor incremental implementation of picture archiving and communications systems
Journal of Digital Imaging - Tập 12 - Trang 71-74 - 1999
Edward M. Smith, John Wandtke, Arvin Robinson
The long-term (10 years) multimodality distributed phased archive for the Medical Information, Communication and Archive System (MICAS) is being implemented in three phases. The selection process took approximately 10 months. Based on the mandatory archive attributes and desirable features, Cemax-Icon (Fremont, CA) was selected as the vendor. The archive provides for an open-solution allowing inco...... hiện toàn bộ
Detection of Microcalcification Clusters Using Hessian Matrix and Foveal Segmentation Method on Multiscale Analysis in Digital Mammograms
Journal of Digital Imaging - Tập 25 - Trang 607-619 - 2012
Balakumaran Thangaraju, Ila Vennila, Gowrishankar Chinnasamy
Mammography is the most efficient technique for detecting and diagnosing breast cancer. Clusters of microcalcifications have been mainly targeted as a reliable early sign of breast cancer and their earliest detection is essential to reduce the probability of mortality rate. Since the size of microcalcifications is very tiny and may be overlooked by the observing radiologist, we have developed a Co...... hiện toàn bộ

Computer-Generated Index for Evaluation of Idiopathic Scoliosis in Digital Chest Images: A Comparison with Digital Measurement
Journal 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
Ultra-Low-Dose Spectral CT Based on a Multi-level Wavelet Convolutional Neural Network
Journal of Digital Imaging - Tập 34 - Trang 1359-1375 - 2021
Minjae Lee, Hyemi Kim, Hyo-Min Cho, Hee-Joung Kim
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
Integrating Natural Language Processing and Machine Learning Algorithms to Categorize Oncologic Response in Radiology Reports
Journal of Digital Imaging - Tập 31 - Trang 178-184 - 2017
Po-Hao Chen, Hanna Zafar, Maya Galperin-Aizenberg, Tessa Cook
A significant volume of medical data remains unstructured. Natural language processing (NLP) and machine learning (ML) techniques have shown to successfully extract insights from radiology reports. However, the codependent effects of NLP and ML in this context have not been well-studied. Between April 1, 2015 and November 1, 2016, 9418 cross-sectional abdomen/pelvis CT and MR examinations containi...... hiện toàn bộ
A psychophysical comparison of two methods for adaptive histogram equalization
Journal of Digital Imaging - Tập 2 - Trang 82-91
John B. Zimmerman, Steve B. Cousins, Karin M. Hartzell, Mark E. Frisse, Michael G. Kahn
Adaptive histogram equalization (AHE) is a method for adaptive contrast enhancement of digital images. It is an automatic, reproducible method for the simultaneous viewing of contrast within a digital image with a large dynamic range. Recent experiments have shown that in specific cases, there is no significant difference in the ability of AHE and linear intensity windowing to display gray-scale c...... hiện toàn bộ
