In Vivo 31P‐MRS of the Human Orthotopic Kidney at 3 Tesla

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
31P‐MRS of healthy human orthotopic kidneys at 3T yielded improved spectral quality within a clinically feasible scan time. The resulting summed spectrum characterizes normal renal phosphorus metabolism and may serve as a reference for detecting metabolic alterations associated with kidney disease and transplantation.

SRS/SBRT commissioning process with a hybrid beam data model in new preconfigured CyberKnife system

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background A new preconfigured CyberKnife system was introduced to improve the SRS/SBRT commissioning efficiency. The vendor provides a reference beam data set, termed “beam data model (BDM)”, and recommends its validation and combination with measurement data to develop a hybrid beam data model (h‐BDM).

Omission of lateral isocenter shifts in robust optimization of proton therapy treatment plans for prostate cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Proton therapy is routinely used to treat prostate cancer using bilaterally opposed beams and can achieve lower dose to nearby organs‐at‐risk (OARs) such as the bladder and rectum. Pencil beam scanning (PBS) proton therapy offers the most conformal treatment plans to best spare healthy tissue.

Correlation of size specific dose estimates with organ dose in abdominal spectral computed tomography

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background In abdominal spectral Computed Tomography (CT), organ dose assessment is important for radiation safety but remains challenging due to the complexity of Monte Carlo (MC) simulations. Purpose This study aimed to compare the correlations of three size‐specific dose estimate (SSDE) metrics (including the central slice SSDEcenter, the ...
