Evaluation of variable relative biological effectiveness and the creation of homogenous biological dose in the tumor region in helium ion radiation to the V79 cell line
In radiation therapy, ions heavier than proton have more biological advantages than a proton beam. Recently, ion helium has been considered due to high linear energy transfer (LET) to the medium and a higher relative biological effect (RBE). To design the spread-out Bragg peak (SOBP) of biological dose for radiation with any type of ion, we need exact values of RBE, which is dependent to dose, ...
متن کاملAdvantages of Helium and Neon Ion Beams for Intelligent Imaging
Scanning electron microscopy (SEM) has become a crucial tool to visualize the exterior morphology and surface structures for samples in both biology and material science. Conventional SEMs are usually limited by relative low resolution and charging effects. Carbon or metal coating is required for insulator samples to minimize charging effects. However, the coating layer can sometimes obscure mi...
متن کاملHeavy Ion Radiotherapy: Yesterday, Today and Tomorrow*
At EO Lawrence Berkeley National Laboratory (LBNL), clinical trials were conducted (1975-1992) for treating human cancer using heavy ion beams, in which about 700 patients were treated with helium-ion and about 300 patients with neon-ion beams. Clinical trials at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany used carbon-ion beams to treat about 250 patients (1997-2005). ...
متن کاملQualitative and quantitative difference in mutation induction between carbon- and neon-ion beams in normal human cells.
We investigated the difference in cell-killing effect and mutation induction between carbon- and neon-ion beams in normal human cells. Carbon- and neon-ion beams were accelerated by the Riken Ring Cyclotron (RRC) at the Institute of Physical and Chemical Research in Japan. Cell-killing effect was measured as the reproductive cell death using the colony formation assay. Mutation induction at the...
متن کاملDeflection of carbon dioxide laser and helium-neon laser beams in a long-pulse relativistic electron beam diode
Deflection of carbon dioxide and helium-neon laser beams has been used to measure plasma and neutral density gradients during the operating mode and after the shorting time of a long-pulse field-emission electron beam diode. Plasma density gradients of (10’4-10’5) cme4 were observed throughout the diode during the fmal microsecond of the 2-3 ps electron beam pulse. The neutral density gradient ...
