introduction hadron-therapy is an effective technique used to treat tumors that are located between or nearby vital organs. the italian national center of oncological hadron-therapy (cnao) has been realized as the first facility in italy to treat very difficult tumors with protons and carbon ions. the on-line monitor system for cnao has been developed by the department of physics of the univers...

nce solely a research tool, the laser is now an enabling technology for a wide range of applications in semiconductor manufacturing and inspection, industrial marking, materials processing, biomedical systems, reprographics, information display, and telecommunications. Given today’s accelerated product-development schedules, laser-based optical systems are being pushed to produce finer resoluti...

The purpose of this study is to describe the comprehensive commissioning process and initial clinical performance of the Vero linear accelerator, a new radiotherapy device recently installed at UT Southwestern Medical Center specifically developed for delivery of image-guided stereotactic ablative radiotherapy (SABR). The Vero system utilizes a ring gantry to integrate a beam delivery platform ...

Hadron radiotherapy is a cutting-edge cancer treatment method. Proton and carbon ion beams are frequently used in modern therapeutic centers. The Bragg peak at the end of the particle range delivers a higher radiation dose to tumors situated close to critical organs. However, the accuracy of the dose deposition in the tumor volume depends on the irradiation method. The present paper presents a ...

Abstract VHEE (Very High Energy Electron) therapy can be superior to conventional radiotherapy for the treatment of deep seated tumours, whilst not necessarily requiring space and cost proton or heavy ion facilities. Developments in high gradient RF technology have allowed electrons accelerated energies a compact space, meaning that could possible with shorter linac. A crucial component is tran...

We describe a novel code system, TRiP, dedicated to the planning of radiotherapy with energetic ions, in particular 12C. The software is designed to cooperate with three-dimensional active dose shaping devices like the GSI raster scan system. This unique beam delivery system allows us to select any combination from a list of 253 individual beam energies, 7 different beam spot sizes and 15 inten...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

For radiotherapy with external beams, quality assurance (QA) of beam delivery is mandatory. Dynamical irradiation which changes parameters of beam delivery devices during the irradiation has to be assessed with a great caution. At GSI a dynamic beam delivery system, so called beam tracking system [1] was developed and integrated into the GSI therapy system [2] to irradiate moving tumours with i...
