Automatic adaptive radiotherapy triggering based on CBCT using deep learning for esophageal cancer underwent volumetric modulated arc therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Esophageal cancer (EC) is a highly fatal malignancy for which radiotherapy plays a critical role in treatment. However, anatomical changes during radiotherapy can lead to increased doses to surrounding organs at risk (OARs). Adaptive radiotherapy (ART) is a strategy that incorporates patient‐specific anatomic changes into treatment ...

PCA‐based respiratory motion modeling for individualized PTV margin optimization in NSCLC radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Respiratory motion remains a major challenge in radiotherapy for non‐small cell lung cancer (NSCLC), often requiring a balance between target coverage and normal tissue sparing. Introduction This study aimed to develop and validate a clinically implementable, individualized PTV margin strategy by integrating principal component ...

Performance evaluation of the binary MLC system on a novel biology‐guided radiotherapy machine using beamlet sequence log data from daily clinical treatments

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Purpose To evaluate the clinical performance of a binary multi‐leaf collimator (MLC) that makes high‐frequency transitions on a novel ring‐gantry medical linac. Methods Beamlet sequence data from treatment plans and daily treatments were retrieved for ten patients treated with image‐guided radiotherapy (IGRT) on the novel machine, with five ...

Selective Targeting of Immune Checkpoints HLA‐G and CD47 Using Novel Dual Signaling Protein DSP216 Promotes Innate Anticancer Immunity

Advanced Science, Volume 13, Issue 35, 24 June 2026.
The inhibitory immune checkpoints HLA‐G and CD47 are expressed on certain tumor types and inhibit immune cells in the tumor microenvironment. DSP216 binds specifically to cancer cells expressing both HLA‐G and CD47, and blocks their inhibitory signaling.

Collision avoidance for CTV: Requirements and capabilities

, 1991
Cargo transfer vehicle (CTV) operations near Space Station Freedom will require positive collision avoidance maneuver (CAM) capability to preclude any change of collision, even in the event of CTV failures. The requirements for CAM are discussed, and the
