Description
Huipeng Meng and co-authors probe a tuning knob in HyperArc radiosurgery planning for small numbers of brain metastases. The aperture shape controller, or ASC, limits how wildly the beam-shaping leaves may move, trading plan complexity against dose accuracy and treatment speed. The team replanned cases for 17 patients with one to three brain lesions, each under six ASC strengths, from off to very high.
Dose quality for tumor and organs at risk did not differ in any firm way across the settings, and neither did the gamma pass rates that check dose truth. Segment counts, complexity scores, and leaf travel were likewise flat. Aperture regularity improved at moderate and high ASC strength. Total monitor units, a proxy for beam-on time, did differ across settings. Planners can raise ASC to tame complexity without paying in dose quality, if they watch delivery time.
