MONTE CARLO MODELING OF THE GAMMA KNIFE PERFEXION<sup>TM</sup>
The Gamma Knife Perfexion<sup>TM</sup> is a radiosurgical treatment device used to irradiate targets in the head such as tumors, blood vessel defects, and malfunctioning nerves. It uses 192 high activity Cobalt-60 sources collimated to a common focus to impart radiological damage to the target …

End-to-end testing of the Leksell Gamma Knife Icon system
The Leksell Gamma Knife Icon is a stereotactic radiosurgery system that is used to non-invasively treat brain lesions. It incorporates 192 fixed cobalt-60 sources, which ensures the highest degree of accuracy during treatment due to the minimization of potential error from stationary sources. The …

A Complete Dosimetric Model of the Gamma Knife Perfexion Using Penelope Monte Carlo Codes
The Gamma Knife Perfexion is a radiosurgical treatment device used to irradiate targets in the head. It uses 192 high-activity Cobalt-60 sources collimated to a common focus to impart radiological damage to the target structure while minimizing dose to adjacent healthy tissue. Tungsten collimators …

New Optimization Technique for Radiation Therapy Planning
… new optimization paradigm, we have applied it to Gamma Knife radiosurgery and High-Dose Rate Brachytherapy (HDR) for prostate cancer. Mathematically, Gamma Knife radiosurgery is a ball-packing process whose goal is to 'pack' some spherical high dose volumes into a tumor volume, while brachytherapy …

Dynamic photon painting
… beams is limited to a few hundred. For example, Gamma Knife radiosurgery, which has long been a gold standard for radiosurgery, uses about two hundred beams. In this research, we investigated the use of Dynamic Photon Painting (DPP) to further increase dose falloff rate. The key idea of DPP is to …

A comparison of health technology adoption in four countries (Japan, Korea, the UK, and the US)
… transplantations, caesarean section deliveries, Gamma knife units and kidney transplants in four countries: Japan, Korea, the UK and the US. The interactions between the micro factors of health technologies and the macro environment in the adoption of health technologies are examined on the basis …

HIGH FIELD MAGNETIC RESONANCE IMAGING-BASED GEL DOSIMETRY FOR SMALL RADIATION FIELDS
Small megavoltage photon radiation fields (< 3cm diameter) are used in advanced radiation therapy techniques, such as intensity modulated radiotherapy, and stereotactic radiosurgery, as well as for cellular and preclinical radiobiology studies (very small fields, <1 mm diameter). Radiation dose …

Commissioning of Micro-Cube Thermoluminescent Dosimeters For Small Field Dosimetry Quality Assurance In Radiotherapy
… assurance and to test this design on linac, Gamma Knife, and CyberKnife treatment delivery machines. The final aim was to use TLD micro-cubes to evaluate photon fields which are smaller than 1.25 cm in diameter.</p> <p>This study was designed by first defining the handling process, including: …
