Research Groups Promoting Proton Therapy “Lite”

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...

Proton Therapy

Methyl groups or additional aromatic groups donate tumour promoting activity.

There are many examples in chemical carcinogenesis in which the introduction of methyl groups or aromatic rings increased the potency of polycyclic hydrocarbons and aromatic amines. Examination of the data in the light of the multistage process of carcinogenesis indicates that these groups convert initiators into complete carcinogens. As complete carcinogens have both initiating and promoting a...

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....

Proton beam therapy physics

Contrary to popular opinion, the concept of treating cancer using high energy beams of protons is not new. First conceived in 1946, following a period in which patients were treated only in laboratory facilities, the first hospital-based facility opened in 1990 at Loma Linda University Medical Center (United States). Currently there are 67 centres in operation, with a further 32 in the construc...
