Status of Electron Beam Ion Sources for Particle Therapy∗
The technical performance of ion sources of the Electron Beam Ion Source (EBIS) type has substantially improved during the last years. This is demonstrated by proof-ofprinciple experiments which have been done using a roomtemperature EBIS, a so-called Dresden EBIS-A, which has been in use for several years. A new superconducting EBIS, a so-called Dresden EBIS-SC, has been taken into operation. ...
متن کاملBeam Monitors of Nirs Fast Scanning System for Particle Therapy
At National Institute of Radiological Sciences (NIRS), more than 6500 patients have been successfully treated by carbon-ion beams since 1994. The successful results of treatments have led us to construct a new treatment facility equipped with three-dimensional pencil beam scanning irradiation system. The commissioning of NIRS fast scanning system installed into the new facility was started in S...
متن کاملDosimetric consequences of pencil beam width variations in scanned beam particle therapy.
Scanned ion beam delivery enables the highest degree of target dose conformation attainable in external beam radiotherapy. Nominal pencil beam widths (spot sizes) are recorded during treatment planning system commissioning. Due to changes in the beam-line optics, the actual spot sizes may differ from these commissioning values, leading to differences between planned and delivered dose. The purp...
متن کاملFocused particle beam-induced processing
In light of the success of 3D printing using fused-deposition modeling or higher-resolution variants with lasers applicable to polymers and metals, one may wonder whether an analogous approach exists on the nanometer scale. Indeed it does. With the aid of focused particle beam-induced deposition (FPBID) it is possible to create solid-state structures on the nanoscale. However, in contrast with ...
متن کاملParticle Beam may have Higher Effectiveness in Treating Chemo-resistant Cancers than Low-LET Photon Beam Therapy.
It is now well-established that outcomes of radiotherapy depend on quality of radiation. A large body of experimental evidences suggests that high-LET (linear energy transfer) radiation or particle radiation has the ability to kill tumor cells more efficiently than low-LET photon beams such as X-rays and γ-rays [1,2]. The unique characteristics of particle beam, which includes precise dose dist...
