Dual‐scan conformal cone‐beam CT for targeted image‐quality improvement using dynamic collimation

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is routinely used for image guidance in radiation therapy, but conventional full‐field CBCT acquisition may expose anatomically irrelevant regions and generate substantial scatter, which degrades soft‐tissue contrast and limits the accuracy of target localization and adaptive radiotherapy ...

Feasibility Study of Combined Systemic Therapy and Carbon‐Ion Radiotherapy for Hepatocellular Carcinoma Patients

open access: yesCancer Medicine, Volume 15, Issue 7, July 2026.
ABSTRACT Background Recent advances in systemic therapy, including tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs), have improved outcomes for hepatocellular carcinoma (HCC) and enabled downstaging strategies that allow subsequent local treatments. Carbon‐ion radiotherapy (CIRT) can provide excellent tumor control with minimal

Methods for Producing Transgenic Plants Resistant to CTV

open access: yes, 2019
Conventional breeding of citrus types demands a long-term effort due to their complex reproductive biology and long juvenile period. As a compelling alternative, genetic engineering of mature tissues allows the insertion of specific traits into specific elite cultivars, including well-known and widely grown varieties and rootstocks, thus reducing the ...

Safety and Efficacy of a Sandwich Total Neoadjuvant Therapy Strategy for Low‐Risk Distal Locally Advanced Rectal Cancer: Results From the TESS Phase II Trial

open access: yesMedComm, Volume 7, Issue 7, July 2026.
The proposed sandwich total neoadjuvant treatment (TNT) strategy (NeoCT–CRT–NeoCT) represents a safe and effective therapeutic option for carefully selected patients with low‐risk distal locally advanced rectal cancer (LARC). By sequentially integrating induction chemotherapy, concurrent chemoradiotherapy, and consolidation chemotherapy, this approach ...
