Radiobiology studies of gold nanoparticle‐enhanced radiosensitization in proton therapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Approximately 50%$\%$ of newly diagnosed cancer patients worldwide receive radiotherapy, most commonly with X‐rays. Proton therapy has emerged as a promising alternative, offering complementary advantages over conventional X‐rays due to its highly localized energy deposition at the Bragg peak, thereby reducing radiation exposure to ...

An ion treatment planning framework for inclusion of nanodosimetric ionization detail through cluster dose

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Nanodosimetry relates the cumulative or statistical moments of Ionization Detail (ID) with biological endpoints of relevance to cancer radiotherapy using charged particles. This association suggests to develop an additional physics‐detailed layer of modeling that may complement biological modeling and treatment planning.

Towards automated dose‐guided patient positioning at clinical timescale in head‐and‐neck cancer proton radiotherapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background In intensity modulated proton therapy (IMPT) accurate patient positioning prior to treatment delivery is important to ensure that the prescribed dose is delivered as intended. Typically, in‐room 3D imaging is utilized to position the patient based on anatomical features, which can be challenging due to interfractional anatomical ...

Photon minibeam‐based LATTICE radiotherapy for small and medium‐sized tumors: A dosimetric planning study

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Lattice radiotherapy (LRT) is a spatially fractionated technique that delivers three‐dimensional high‐dose vertices within tumors. However, conventional LRT is constrained by geometric limitations when applied to small and medium‐sized tumor volumes, primarily due to the large beam sizes that restrict optimal lattice pattern ...

A comparison of relative stopping power derived by fast kV‐switching dual‐energy CT, single‐energy CT, and proton CT in phantom and tissue

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background The accuracy of relative stopping power (RSP) is a critical aspect for safe treatment planning in proton therapy. Dual‐energy CT (DECT) has the ability to estimate RSP more accurately than conventional single‐energy CT (SECT) due to its improved material separation. RSP accuracy is commonly determined in homogeneous phantom material
