In the treatment of superficial lesions with 8-13 MeV electrons, lead shields are often used to protect the underlying tissue. Measurements were made with film and ion chamber to analyse various aspects of external and internal shielding in electron beam therapy. Data were obtained on the thickness of lead required for shielding, the effect of blocking on dose-rate, electron-backscattering from...
background: radiation therapy is among the most conventional cancer therapeutic modalities with effective local tumor control. however, due to the development of radio-resistance, tumor recurrence and metastasis often occur following radiation therapy. in recent years, combination of radiotherapy and gene therapy has been suggested to overcome this problem. the aim of the current study was to e...
Consider potential of gold nanoparticles with proton therapy compared with KV and MEV X-ray therapy.
Introduction: Many study shown the effectiveness dose enhancement with gold nanoparticles (GNPs), especially with low-energy x-rays. Recently, proton beam radiation therapy (PBRT) has attention as a treatment for tumors. The advantage in PBRT, which releases high dose at the controllable Bragg peak position that localized for Au target and the released dose increased in depth....
