Positive perspectives from proton therapy

Proton Therapy of eye using MCNPX code

Introduction: Proton radiotherapy is the one of advanced teletherapy methods. The protons deposit their maximum energy in a position called Bragg peak. Therefore, for treatment of cancer, the tumor should be placed at the Bragg peak or SOBP. The scattered photons and neutrons is a challenge in proton radiotherapy. The aim of this study is calculation of absorbed dose from scatt...

Feminist Therapy: A Review From Two Perspectives

The current review represents the views of two reviewers who approach the book from very different perspectives. While Mary Ballou is a colleague of the book author, has participated in the development of feminist theory over the past few decades, and has written collaboratively with Brown, Elizabeth Markle is relatively new to the literature on feminist therapy. Therefore, this review combines...

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....
