Abstract

280 MeV/nucleon nitrogen ion beam was stopped in a beryllium target. Radioactive isotope ¹¹C (half life 20.34 min) has been produced by the fragmentation of the incident ion. We call this phenomenon “auto activation”.

An overview of recent developments in FLUKA PET TOOLS
2018, Physica Medica
The new developments of the FLUKA Positron-Emission-Tomography (PET) tools are detailed. FLUKA is a fully integrated Monte Carlo (MC) particle transport code, used for an extended range of applications, including Medical Physics. Recently, it provided the medical community with dedicated simulation tools for clinical applications, including the PET simulation package. PET is a well-established imaging technique in nuclear medicine, and a promising method for clinical in vivo treatment verification in hadrontherapy. The application of clinically established PET scanners to new irradiation environments such as hadrontherapy requires further experimental and theoretical research to which MC simulations could be applied. The FLUKA PET tools, besides featuring PET scanner models in its library, allow the configuration of new PET prototypes via the FLUKA Graphical User Interface (GUI) Flair. Both the beam time structure and scan time can be specified by the user, reproducing PET acquisitions in time, in a particle therapy scenario. Furthermore, different scoring routines allow the analysis of single and coincident events, and identification of parent isotopes generating annihilation events. Two reconstruction codes are currently supported: the Filtered Back–Projection (FBP) and Maximum–Likelihood Expectation Maximization (MLEM), the latter embedded in the tools. Compatibility with other reconstruction frameworks is also possible. The FLUKA PET tools package has been successfully tested for different detectors and scenarios, including conventional functional PET applications and in beam PET, either using radioactive sources, or simulating hadron beam irradiations. The results obtained so far confirm the FLUKA PET tools suitability to perform PET simulations in R&D environment.
Effective source size, radial, angular and energy spread of therapeutic 11C positron emitter beams produced by 12C fragmentation

However, it was recently shown that sufficiently intense 11C ion beam with a suitable mean energy to reach even deep sited tumors could be produced during the deceleration of an incoming low emittance 12C beam provided the target material was carefully selected [11]. The mentioned projectile fragmentation method partially follows the steps of the pioneering studies conducted at the Lawrence Berkeley Laboratory [12–14], during the EULIMA collaboration [15], and subsequently further developed at the Japanese facility of HIMAC [4,5,16]. With the target material chosen by the Japanese group (beryllium) the outcoming intensity of the 11C particles varied from 0.1% to 1% of the primary 12C ion beam intensity [17], depending on the momentum acceptance of the beam line.
The use of positron emitter light ion beams in combination with PET (Positron Emission Tomography) and PET–CT (Computed Tomography) imaging could significantly improve treatment verification and dose delivery imaging during radiation therapy.
The present study is dedicated to the analysis of the beam quality in terms of the effective source size, as well as radial, angular and energy spread of the ¹¹C ion beam produced by projectile fragmentation of a primary point monodirectional and monoenergetic ¹²C ion beam in a dedicated range shifter of different materials. This study was performed combining analytical methods describing the transport of particles in matter and the Monte Carlo code SHIELD-HIT+.
A high brilliance and production yield of ¹¹C fragments with a small effective source size and emittance is best achieved with a decelerator made of two media: a first liquid hydrogen section of about 20 cm followed by a hydrogen rich section of variable length.
The calculated intensity of the produced ¹¹C ion beam ranges from about 5% to 8% of the primary ¹²C beam intensity depending on the exit energy and the acceptance of the beam transport system. The angular spread is lower than 1 degree for all the materials studied, but the brilliance of the beam is the highest with the proposed mixed decelerator.
Present and future sources of protons and heavy ions
1977, International Journal of Radiation Oncology, Biology, Physics
A brief outline of existing medical heavy-ion facilities is given. The beam specifications for future dedicated medical ion accelerators are discussed. Machines capable of delivering dose rates of approximately 1 krad/min in volumes of a few liters are shown to represent existing technology. A cost and performance analysis shows the synchrotrons to be the most economical source for the heavier ions while conventional cyclotrons seem optimal for an exclusive proton facility. It is seen that the incorporation of additional capabilities such as neutron generation or radioisotope production can be achieved at modest incremental costs.
In addition to the accelerators, feasible layouts of hypothetical facilities are discussed, and three-dimensional beam scanning is shown to allow the irradiation of large volumes without sacrificing the precise dose localization capabilities of heavy-ion beams. Concepts of quality-controlled engineering and modern computer technology are introduced as a means to obtain the desired high degree of reliability and ease of operation and maintenance.
Particle radiography and autoactivation
1977, International Journal of Radiation Oncology, Biology, Physics
Two new techniques are being developed using accelerated heavy-ion beams that will allow better localization of deep-seated tumors and diagnostic imaging adjustment of therapy beams. Both depend on the unique physical characteristics of the interaction of heavy particles with matter. Heavy-ion radiography uses monoenergetic particle beams for imaging the distribution of electron densities in tissue with very high sensitivity for small density differences. It is based on the exact range-energy relationship of heavy particles. Images are obtained of the pattern of stopping heavy ions in a stack of plastic nuclear detector foils. Differences as small as 0.2% in tissue stopping power have been detected and measured. Work is in progress on computerized tomography. 260 MeV/nucleon carbon ions give considerably better depth and lateral resolution than protons or helium ions at low doses. When ordinary heavy-ion beams pass through matter, some of the particles become radioactive and form an “autoradioactive” component of the beam. Following deposition of the radioactive particles, γ-ray coincidence techniques have been used to measure the depth penetration of the beam in tissue. Work is in progress on a special γ-ray camera to image the distribution of beam stopping regions; since measurements are made between beam pulses, this technique can be used to alter by feedback methods the range penetration of the therapy beams. ¹¹₆C, ¹⁵₈O and ¹⁹₂₀Ne isotopes have been used. In the future, it may be feasible to use pure radioactive heavy-ion beams for therapy with simultaneous imaging of the therapy distribution.
