Abstract Background Stereotactic ablative radiotherapy (SABR) with dose escalation is increasingly used for pancreatic cancer; however, the dosimetric impact of metallic biliary stents remains poorly characterized. Self‐expanding metal stents (SEMS), commonly placed for obstructive jaundice, contain high‐density nitinol that produces computed ...

Abstract Background Radiotherapy for vulvar carcinoma often employs the “frog‐leg” position to minimize skin toxicity, but this position is biomechanically unstable and prone to setup errors using conventional skin markings. Purpose To evaluate the clinical efficacy of Surface‐Guided Radiotherapy (SGRT) for setup accuracy in vulvar cancer patients ...

Abstract Background Volumetric‐modulated arc therapy (VMAT) represents a standard of care for head and neck cancer (HNC). However, treatment plan quality depends heavily on the planner's expertise, thereby challenging the standardization of treatment quality.

Abstract Additively manufactured (3D‐printed) surgical reconstruction implants are increasingly encountered in head and neck oncology and may introduce density assignment challenges during radiotherapy treatment planning. This case report describes a clinically significant dosimetric discrepancy arising from the application of nominal bulk material ...

Abstract Background Accurate dose deposition in superficial radiotherapy remains challenging due to the inherent skin‐sparing effect of megavoltage photon beams and difficulties in ensuring bolus conformity. Purpose This study aims to comprehensively evaluate the dosimetric characteristics of the room‐temperature‐malleable high‐density bolus, to ...

Abstract Background Flattening filter‐free (FFF) beams are increasingly deployed for stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS). The Elekta Versa HD (VHD) and Varian TrueBeam (TB) are the two most widely used FFF‐capable platforms; however, no prior study has compared their 6 MV FFF commissioning parameters under fully ...

Abstract Background The current standard radiotherapy treatment planning workflow typically requires several hours to days, during which patients must wait before treatment can be initiated. In certain oncological situations, however, treatment should commence as soon as possible.
