TL;DR: The rapid delivery of SRS and SBRT with RapidArc improved workflow on the linac with these otherwise time-consuming treatments and limited the potential for intrafraction organ and patient motion, which can cause significant dosimetric errors.

Defining functional changes in the brain caused by targeted stereotaxic radiosurgery.
TL;DR: The results suggest that certain cognitive decrements are linked to changes in neurogenesis, and that the unilaterally irradiated brain exhibits distinct neurogenic responses that may be regulated by regional differences in neuroinflammation.

TL;DR: A 12-week, low-cost telehealth training program on HDR brachytherapy improved confidence in treatment delivery and teaching for clinicians in 10 participating LMICs and demonstrated increases in confidence in all 15 competencies.
Stem cell transplantation strategies for the restoration of cognitive dysfunction caused by cranial radiotherapy.
TL;DR: Cognitive testing paradigms have demonstrated that animals engrafted with hNSCs exhibit significant improvements in cognitive function, suggesting that this procedure may one day afford a promising strategy for the long-term functional restoration of cognition in individuals subjected to cranial radiotherapy.
Dosimetric characteristics of the Novoste Beta-Cath 90Sr/Y source trains at submillimeter distances.
TL;DR: Measurements were performed on the 30, 40, and 60 mm 90Sr/Y beta-emitter source trains used in the Novoste Beta-Cath system to determine their dosimetric characteristics at submillimeter distances and provide the necessary TG-60 parameters for mapping their dose distributions.
