Subjective Evaluation of the In-Line Phase-Sensitive Imaging Systems in Breast Cancer Screening and Diagnosis
(2022-08-04)
Breast x-ray imaging remains the gold standard screening tool despite the various imaging modalities. The phase-sensitive breast imaging is an evolving technology that may provide higher diagnostic accuracy and potentially ...
TECHNIQUES AND INSTRUMENTATION FOR PHASED ARRAY CALIBRATION
(2020-05-08)
Active phased arrays suffer the inherent problem of excitation errors, i.e., incorrect phase and amplitude excitation of the antenna elements. Excitation errors degrade critical performance parameters since they increase ...
Artificial Intelligence-based Network Modeling for enabling Zero Touch Automation in Next Generation Cellular Networks
(2023-08-04)
The crux of contemporary network design involves mathematical models to describe the quantitative impact of system components on overall performance. However, these models often grapple with trade-offs between accuracy and ...
RF Modeling and Electromagnetic Analysis of Implantable Devices in Magnetic Resonance Imaging
(2017-12)
Magnetic Resonance Imaging (MRI) has become a generally accepted medical procedure and it is estimated that all the U.S. population will have at least one MRI scan in their lifetime. Unlike common radiography and computed ...
Design of low-density parity-check codes for magnetic recording channels.
(2002)
A technique for designing low-density parity-check (LDPC) error correcting codes for use with the partial-response channels commonly used in magnetic recording is presented. This technique combines the well-known density ...
Applying novel machine learning technology to optimize computer-aided detection and diagnosis of medical images
(2021-05-14)
The purpose of developing Computer-Aided Detection (CAD) schemes is to assist physicians (i.e., radiologists) in interpreting medical imaging findings and reducing inter-reader variability more accurately. In developing ...
A real-time multitarget tracker by adaptive hypothesis testing for airborne surveillance systems.
(1982)
A multitarget, multisensor tracking algorithm is formulated specifically for the environment of an airborn surveillance system. The algorithm divides report/track pairs into unique associations and clusters of cross ...
TOWARD A MORE CLARIFIED DETECTIVE QUANTUM EFFICIENCY METHODOLOGY: STUDY OF THE DQE THEORY AND APPLICATIONS
(2009)
Detective quantum efficiency (DQE) is widely accepted as the golden rule to objectively evaluate the performance of x-ray imaging systems. It provides a comprehensive characterization of an x-ray imaging system, because ...
