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.

Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms

New Phytologist, Volume 252, Issue 1, Page 427-442, October 2026.
Variation in key fern genomic traits across families, mapped onto a summary phylogenetic tree. Summary Ferns and angiosperms represent the two largest vascular plant lineages but exhibit striking genomic and ecological contrasts. We investigated whether differences in genome size, chromosome architecture, GC content, and stomatal traits reveal ...

Mutual antagonism between auxin and diacylglycerol acyltransferase 2 regulates high‐temperature‐induced hypocotyl elongation

New Phytologist, Volume 252, Issue 1, Page 222-240, October 2026.
Proposed model for auxin–DGAT2 crosstalk regulating high‐temperature‐induced hypocotyl elongation. Summary Cell elongation is a fundamental process in plant growth and development, and it is significantly affected by temperature changes. While the signaling mechanisms driving high‐temperature‐induced cell elongation have been extensively studied, the ...

The combination of morphogenic regulators BABY BOOM and GRF‐GIF improves maize transformation efficiency and promotes leaf regeneration

New Phytologist, Volume 252, Issue 1, Page 260-275, October 2026.
Maize regeneration via somatic embryogenesis by ectopic expression of morphogenic factors TaGRF4‐TaGIF1 and ZmBBM. Summary Transformation is an indispensable tool for plant genetics and functional genomics. Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic ...

Beam geometry optimization and convergence mode evaluation for knowledge‐based planning of hippocampal avoidance whole‐brain radiotherapy: A cross‐platform study with quantitative scorecard assessment

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Hippocampal avoidance whole‐brain radiotherapy (HA‐WBRT) is used to treat brain metastases while preserving cognitive function by sparing the hippocampi. Volumetric modulated arc therapy (VMAT) is commonly used due to its ability to generate conformal dose distributions.
