Abstract This paper reviews reported methods of the electrochemical deposition nickel layers which are used as target materials for accelerator production medical radioisotopes. The review focuses on electrodeposition carried out from aqueous electrolytes. It describes main challenges related to preparation suitable Ni layers, such work with limited amounts expensive isotopically enriched nicke...

The experimental results on DDX (double differential neutron production cross section data), TTY (thick target neutron production yield data), heavy-ion produced neutron transport data, and spallation products production cross section data taken at Heavy Ion Medical Accelerator (HIMAC), National Institute of Radiological Sciences (NIRS), Japan, are presented for heavy ions of He to Xe in the en...

The demand for clinical use of accelerated heavy chargedparticle (proton and light-ion) beams for cancer treatment is now burgeoning worldwide. Clinical trials are underway at more than a dozen accelerators. Several hospital-based accelerator facilities dedicated to radiation treatment of human cancer have been constructed, and their number is growing. Many instruments in medical systems have b...

The goal of this project is to develop a compact device which can produce an intense flux of monochromatic Xrays for medical applications. It is based on Compton back-scattering resulting from collisions between laser pulses and relativistic electron bunches. Intense laser beams can be obtained with a high gain Fabry-Perot cavity coupled with either a high average power fiber amplifier or a hig...

The present work is devoted to develop a computational model using the Monte Carlo code MCNP5 (Monte Carlo N-Particle) for the simulation of a 6 MV photon beam given by Elekta Precise medical linear accelerator treatment head. The model includes the major components of the multileaf accelerator head and a cube-shaped water tank. Calculations were performed for a photon beam with 10 cm x 10 cm i...

Radiation therapy is an established method of cancer treatment. New technologies in cancer radiotherapy need a more accurate computation of the dose delivered in the radiotherapy treatment plan. This study presents some results of a Geant4-based application for simulation of the absorbed dose distribution given by a medical linear accelerator (LINAC). The LINAC geometry is accurately described ...

Medical robotics is an exciting and relatively new field. Robotics plays an important role in medical engineering. Medical robots were initially used in the 1980s, in the field of urology. Robotic arms were developed and used for prostate resection. They can also be highly specialized and assist in diagnosing and treating patients. While there is still much more work to be done, using robots ca...

In this paper, we present an accelerator that is designed to improve performance of network processing applications, particularly layer seven networking applications. The accelerator can easily be integrated in Network Processors. We present the design details of two different FPGA implementations: a design where each task is implemented in the accelerator and another one where the accelerator ...
