Purpose: Ultrahypofractionation presents challenges for a subset of high-risk prostate cancer patients due to the large planning target volume (PTV) margin required for the seminal vesicles. Online adaptive radiation therapy could potentially reduce this margin. This paper focuses on the development, preclinical validation, and clinical testing of online adaptive robotic stereotactic body radiation therapy for this patient group.

Background And Purpose: A novel ring-gantry cone-beam computed tomography (CBCT) imaging system shows improved image quality compared to its conventional version, but its effect on autosegmentation is unknown. This study evaluates the impact of this high-performance CBCT on autosegmentation performance, inter-observer variability, contour correction times and delineation confidence, compared to the conventional CBCT.

Materials And Methods: Twenty prostate cancer patients were enrolled in this prospective clinical study.

Background: This study was undertaken to understand the role of the Health Care Assistants and how they negotiate roles and responsibilities with Registered Nurses in adult acute hospitals.

Methods: The qualitative approach of focused ethnography used non-participant observation and interviews with staff from four acute wards. Field notes and interview data, analysed using NVIVO10, moved data from description through explanation, interpretation and identification of themes.

Article Synopsis
  • * The study introduces enhanced modeling techniques for neutrino flux and detector response, and it distinguishes between starting (inside) and throughgoing (outside) neutrino interaction events to improve energy resolution.
  • * The findings indicate a best-fit point for the 3+1 model with sin²(2θ_{24})=0.16 and Δm_{41}²=3.5 eV², supporting previous studies while showing consistency with no evidence of sterile neutrinos, as reflected
