ON THE IMPACT OF IMPROVED DOSE CALCULATION ACCURACY IN CLINICAL TREATMENT PLANNING FOR SUPERFICIAL HIGH-DOSE-RATE BRACHYTHERAPY OF EXTENSIVE SCALP LESIONS

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.Treatm

The effect of intermediate stress (in situ tunnel axial) on a strainburst is studied with a three-dimensional (3D) bonded block distinct element method (DEM).A series of simulations of strainbursts under true triaxial in situ stress conditions (i.e.high tangential stress, moderate intermediate stress and low radial stress) of near-boundary rock mas

Chemical vapor deposition synthesis of graphene on copper foil from methane is the most promising technology for industrial production.However, an important problem of the formation of the additional graphene layers during synthesis arises due to the strong roughness of the Dog-Harnesses initial copper foil.In this paper, various approaches are dem

Recurring green tides (also called Ulva prolifera) cause significant damage to marine ecosystems in the Yellow Sea of China, especially in the settlement region.The settlement region is a critical area for the natural decay and decomposition of green tides, which obviously has ecological consequences.Recent studies in relation to this topic are mos

High-resolution water depth data are of great significance in island research and coastal ecosystem monitoring.However, the acquisition of high-resolution imagery has been a challenge due to the difficulties and high costs associated with obtaining such data.To address this issue, this study proposes a water depth inversion method based on Gaofen-1
