National Institutes for Quantum Science and Technology (QST, successor organization of National Institutes for Radiological Science) started carbon ion particle therapy in 1994.
Based on positive clinical results, carbon-ion radiotherapy was authorized as a Highly Advanced Medical Technology by Japanese government from 2003 and treatment for some kinds of cancers was applied to Japanese...
Centre for Medical Radiation Physics at University of Wollongong has long history of development of the silicon radiation detectors for dosimetry in X-ray and particle radiation therapy. Overview of the developed pixelated Si detectors and their applications for high spatial and temporal resolution dosimetry on medical linac and on proton and heavy ion therapy will be presented.

According to the data and analysis of the Cancer Registry Annual Report in Taiwan, it can be seen from the trends in the past 10 years in 2020 that the growth in the incidence of major cancers is approximately 3.32% in the number of patients per year. The first new case of aggressive cancer finding in Taiwan is 116,131 and there are 30,796 patients received radiation therapy during the first...
Magnetic design and beam optics studies have been carried out for a K100 cyclotron, which can accelerate Q/A=1/2 ions to the maximum energy of 25 MeV/u. Since proton acceleration using H2+ instead of H+ or H- can double the maximum beam current primarily limited by space charge effects at the injection energy of compact cyclotron, we expect a maximum current of over 2 mA can be achieved by...
The 6-MeV and 9-MeV electron linear accelerators (LINACs) were designed and constructed in 2015 and in 2018 at the Dongnam Institute of Radiological & Medical Sciences (DIRAMS), Busan, Korea. Their C-band accelerating columns were chosen as a bi-periodic on-axis coupled structure and operated in the π/2 standing-wave mode. They are used for preclinical irradiators for in vitro studies of cells...
Various types of radioisotopes (RIs) are used in the field of nuclear medicine for diagnosis, such as PET and SPECT. In recent years, RIs are applied to therapy of cancer and the Ac-225 has been confirmed to be effective in the treatment of advanced cancer. One of the promising RI production methods for medical application is the use of high-intensity beam in accelerators. In the case of an...
Introduction: Detectors that can provide accurate dosimetry for microbeam radiation therapy (MRT) must satisfy a number of challenging criteria including having intrinsic radiation hardness, a high dynamic range, energy and dose rate independence, and a spatial resolution able to resolve x-ray microbeam spacings on the order of hundreds of microns.
At the Centre for Medical Radiation...
FLASH radiotherapy (RT) is an emerging cancer treatment modality that utilises much higher dose rates than conventional RT. Delivering radiation with ultra-high dose rates (UHDR) has been shown to spare healthy tissue while providing an equal or greater dose to the tumour. Current research suggests the use of very high-energy electrons can provide further benefits, such as treatment of deep...
This work presents recent achievements in development and applications of ANSTO’s ANTARES [1] and SIRIUS [2] microprobe systems for the high-precision irradiation of materials and devices for prototyping and applications to microelectronics, photovoltaics and space. The ANSTO systems can be optimized to deliver a required combination of linear energy transfer, ion range, scanning size and...
In recent years, Boron Neutron Capture Therapy (BNCT) has seen vigorous development, and the BNCT facility (D-BNCT) at the People's Hospital of Dongguan City, Guangdong Province, is also under construction. This report introduces the design and implementation of the accelerator control system for D-BNCT, which utilizes the Experimental Physics and Industrial Control System (EPICS) as the...
Access to proton therapy is limited by both facility cost and existing technological limitations. The beam delivery system (BDS) has been identified as a bottleneck, particularly for new and emerging methodologies such as FLASH, Arc, and multi-ion therapies. This talk will discuss a new collaborative project between Harvard/MGH, University of Melbourne and Pyramid technologies for a compact,...
Linac-based coherent THz radiation sources are being developed with the NSRRC high brightness photoinjector which has been installed in the Accelerator Test Area (ATA). The injector is equipped with a laser-driven photocathode rf gun and a 5.2-m long S-band traveling-wave linac for beam acceleration. A 25 MeV beam of bunch length as short as 240 fs has been produced from this injector by the...
As echoing to the national demanding for industry development, the Industry Application Division (IAD) in the National Synchrotron Radiation Research Center (NSRRC) in Taiwan was established and launching its mission since 2008. Serving as the acting window in NSRRC, the IAD bridges the synchrotron-radiation (SR) analytical tools mainly to key domestic industries with practical and critical...
