TG-43-based dose calculations disregard tissue heterogeneities and finite scatter conditions. prompting the introduction of model-based dose calculation algorithms (MBDCAs) to improve accuracy in high-dose-rate (HDR) brachytherapy. This study evaluated the effectiveness of MBDCAs over TG-43 in HDR 192Ir brachytherapy of extended scalp lesions. Treatment planning dose calculations were... https://jalyttlers.shop/product-category/hat/
