“…Just like the above mentioned superconducting proton gantries, it is based on a series of dipoles and quadrupoles. A more compact version of this gantry with a reduction of about 2/3 in size and weight is in preclinical commissioning at Yamagata University and a rotating gantry of the same type is to be installed for the Yonsei University Health System (Seoul, South Korea) and Seoul National University Hospital (Seoul, South Korea) [66]. An even more compact version is being designed in collaboration with Toshiba (Tokyo, Japan) [67].…”

In the last decades, important technological progress has been made to enhance the quality and efficiency of particle therapy treatments. Continuous improvements in dose delivery, treatment planning and verification techniques have lead to higher dose conformity and better sparing of healthy tissue. At the same time, particle therapy treatments are complex and much more expensive than conventional radiotherapy, and only highly specialized facilities can offer these treatments. Cost reduction is thus a strong drive behind technological developments in the field. The number of treatment facilities offering proton and carbon therapy has strongly grown in the last decades, and the amount of research efforts and innovations have increased continuously.From a technological perspective, advances in hardware are often accompanied by innovations in software and computation, and vice versa. In this review we will present a basic overview of technological advances in particle therapy hardware (accelerators, gantries, applications of superconductivity, treatment verification techniques), software (Monte Carlo simulations, treatment planning calculations), and studies towards clinical applications. By combining a broad selection of topics into a single review and by covering both proton and carbon therapy, we aim at providing the reader a unique overview of the evolution of various technologies developed for particle therapy.

“…For example, a CIRT facility in Yamagata prefecture in Japan and one under construction at Yonsei University in Seoul have the latest superconducting rotating gantry that is 2/3 the size of the gantry in QST Hospital, Japan. This is due to a more compact novel design of scanning magnets that are 1/3 smaller than the existing ones at QST Hospital and an increase of the magnetic field strength in the superconducting magnets ( 116 ).…”

In this review, we attempt to make a case for the establishment of a limited number of heavy ion cancer research and treatment facilities in the United States. Based on the basic physics and biology research, conducted largely in Japan and Germany, and early phase clinical trials involving a relatively small number of patients, we believe that heavy ions have a considerably greater potential to enhance the therapeutic ratio for many cancer types compared to conventional X-ray and proton radiotherapy. Moreover, with ongoing technological developments and with research in physical, biological, immunological, and clinical aspects, it is quite plausible that cost effectiveness of radiotherapy with heavier ions can be substantially improved.

Recent accelerator projects for radiation-therapy centers demand strongly curved magnets in transfer lines and gantries. Several advances have been achieved in designing and manufacturing strongly curved, cosine-theta, and canted-cosinetheta type magnets. This paper presents a new computer-aided design (CAD) engine for generating coil geometries for various types of mandrel surfaces (elliptical, curved, conical) and interfacing with field simulation software as well as CAD tools. The CAD engine is based on the differential geometry of the Frenet frame and allows the analytical computation of the curvature parameters, such as curvature, twist, and torsion. Applying the theory of developable surfaces it is possible to generate conductor geometries with zero Gaussian curvature, which are particularly interesting for strain-sensitive supercondors such as high-temperature superconductor tapes.
