Super-resolution imaging in a multiple layer EPID [PDF]

Biomedical Physics & Engineering Express, 2017
Abstract A new portal imager consisting of four vertically stacked conventional electronic portal imaging device layers has been constructed in pursuit of improved detective quantum efficiency. We hypothesize that super-resolution (SR) imaging can also be achieved in such a system by shifting each layer laterally ...

Early Interaction Between Scripture, Rule of Faith, and Evolving Christian Doctrine and Tradition: A Response to Alister McGrath’s The Nature of Christian Doctrine

International Journal of Systematic Theology, EarlyView.
Abstract This response to Alister McGrath’s The Nature of Christian Doctrine examines the interplay between Scripture, the Rule of Faith, and evolving Christian doctrine and tradition. Focusing on McGrath’s critique of Lindbeck’s presentation of doctrinal modalities, the article explores how doctrinal formation involves primarily synchronic (canonical),

A review of electronic portal imaging devices (EPIDs) [PDF]

Medical Physics, 1992
On‐line electronic portal imaging devices are beginning to come into clinical service in support of radiotherapy. A variety of technologies are being explored to provide real‐time or near real‐time images of patient anatomy within x‐ray fields during treatment on linear accelerators.

Reporting treatment planning, delivery, and dose evaluation for 3‐dimensional MLC‐based SFRT: A single institutional clinical experience

Journal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Purpose/Objective We report our institutional clinical experience of treatment planning, dose evaluation, and delivery via the same‐day 3D MLC‐based crossfire method for spatially fractionated radiotherapy (SFRT) in conjunction with combination therapy. Additionally, we aimed to model our clinical outcome data to provide clinical insights into
