Background and purpose Interfraction volumetric changes/rotations in the prostate and
proximal seminal vesicles (SVs) might compromise target coverage when tight margins are …

Purpose Stereotactic magnetic resonance (MR)–guided adaptive radiation therapy (SMART)
for prostate cancer allows for MR-based contouring, real-time MR motion management, and …

Purpose: To assess the optimal planning target volume (PTV) margins for stereotactic body
radiotherapy (SBRT) of prostate cancer based on inter-and intra-fractional prostate motion …

Background The assessment of organ motion is a crucial feature for prostate stereotactic
body radiotherapy (SBRT). Rectal spacer may represent a helpful device in order to …

Purpose To reconstruct the dose delivered during single-fraction urethra-sparing prostate
stereotactic body radiotherapy (SBRT) accounting for intrafraction motion monitored by …

Purpose To determine whether image guidance with rigid registration (RR) to intraprostatic
markers (IPMs) yields acceptable coverage of the pelvic lymph nodes in the context of a …

Background and purpose Accurate delivery of radiotherapy is critical to achieve optimal
treatment outcomes. Interfraction translational IGRT is now standard, and intrafraction …

Objectives: To measure the magnitude of intra-fraction prostate motion (IFPM) during
stereotactic radiotherapy (SBRT) delivered without intra-fraction tracking. To assess if …

Background Stereotactic body radiotherapy (SBRT) is becoming increasingly used in
treating localized prostate cancer (PCa), with evidence showing similar toxicity and efficacy …

PURPOSE: The objectives of this study were to quantify residual interfraction displacement
of seminal vesicles (SV) and investigate the efficacy of rotation correction on SV …
