Derivation of an Observer Model Adapted to Irregular Signals Based on Convolution Channels
Ivan Diaz,Craig K. Abbey,Pontus Timberg,Miguel P. Eckstein,Francis R. Verdun,Cyril Castella,François Bochud +6 more
TL;DR: A new linear model observer based on convolution channels is derived, referred to as the “Filtered Channel observer” (FCO), as an extension of the channelized Hotelling observer (CHO) and the nonprewhitening with an eye filter (NPWE) observer, which can take the form of a single template with an external noise term.
Proceedings ArticleDOI
Human-observer templates for detection of a simulated lesion in mammographic images
Craig K. Abbey,Miguel P. Eckstein,Steven S. Shimozaki,Alan H. Baydush,David Mark Catarious,Carey E. Floyd +5 more
TL;DR: A probit regression approach for maximum-likelihood (ML) estimation of a linear observer template from human-observer data in two-alternative forced-choice experiments that constrain the observer template to be represented by a limited number of linear features.
Proceedings ArticleDOI
Improved image guidance of coronary stent deployment
TL;DR: It is demonstrated that layer decomposition of a clinical cine x-ray image sequence greatly improves the visibility of a previously deployed stent and it is shown that layer decayposition of contrast-filled vessels removes background structures and reduces noise.
Journal ArticleDOI
Simulating coronary arteries in x‐ray angiograms
Craig A. Morioka,Craig K. Abbey,Miguel P. Eckstein,Robert A. Close,James S. Whiting,Michelle T. LeFree +5 more
TL;DR: This work embedding simulated coronary artery segments with known geometry in clinical angiograms with good agreement in the measured diameters with measurements of an x-ray Telescopic-Shaped Phantom with the same diameters are compared.
Proceedings ArticleDOI
Observer efficiency in discrimination tasks simulating malignant and benign breast lesions with ultrasound
TL;DR: This work uses the ideal observer approach to investigate performance in a number of tasks idealized from the use of ultrasonic imaging for the discrimination of malignant and benign breast tissue and reports the statistical efficiency of human observers in these tasks-as evaluated by psychophysical studies-with respect to the ideal observers.
