- ПубликацияТолько метаданныеEmission and X-ray characteristics of vertically and random aligned carbon nanotubes(2020) Ilin, O. I.; Koltunova, N. V.; Rudyk, N. N.; Savin, V. I.; Bratsuk, A. V.; Kiselev, D. S.; Simonov, A. A.; Taubin, M. L.; Киселев, Дмитрий Сергеевич; Таубин, Михаил Львович© 2020 American Institute of Physics Inc.. All rights reserved.Carbon nanotubes (CNTs) have gained great popularity due to their unique physicochemical properties. In this work, an important advantage of CNTs is the cold emission of electrons, which occurs when only an electric field is supplied to the nanotube. The use of CNTs as electron emitters in X-ray sources provides several advantages, which allows the use of X-ray sources in the treatment of a number of oncological diseases. In this work, we compared the emission and X-ray characteristics of random and vertically aligned carbon nanotubes (VACNTs). Random CNTs were synthesized by the method of atmospheric pressure alcohol catalytic chemical vapor deposition (AP ACCVD), and VACNTs were synthesized using plasma chemical vapor deposition (PECVD). It was found that random CNTs provided an X-ray dose rate of 1.4 Gy/h at an emission current density of 4 mA/cm2and an electric field of 2.05 V/μm, while VACNTs provided 0.63 Gy/h at an emission current density of 0.2 mA/cm2and an electric field of 4.8 V/μm. The characteristics of both random CNTs and VACNTs obtained at room temperature are already acceptable for single fractions in contact therapy of some oncological diseases (for example, skin cancer).
- ПубликацияТолько метаданныеExperimental studies of emissive and dosimetry characteristics of ultra-compact x-ray emitters(2020) Bugorkov, S. D.; Golovin, N. A.; Savin, V. I.; Koltunova, N. V.; Taubin, M. L.; Bratsuk, A. V.; Simonov, A. A.; Таубин, Михаил Львович© 2020 American Institute of Physics Inc.. All rights reserved.In this research we developed an ultra-compact X-ray tubes. The paper presents the results of investigations into the emission and dose characteristics of ultra-compact X-ray tubes. The dose distribution in the anode area along the height and azimuth of the X-ray tube is shown. The data on the dose dependence on time during exposure are illustrated.
- ПубликацияТолько метаданныеA Miniature Source of Ionizing Radiation for Electronic Brachytherapy(2019) Chesnokov, D. A.; Taubin, M. L.; Таубин, Михаил Львович© 2019, Springer Science+Business Media, LLC, part of Springer Nature.The paper presents a miniature source of ionizing radiation for intracavitary therapy of cancer. The developed source can be implanted near the tumor. It is shown that small radiation sources can provide satisfactory treatment results if made of new materials that have not been previously used in X-ray technology. The results of a model study of the radiation dose emitted by the source are presented. The developed source can be used in gynecology, urology, proctology, mammology, etc.
- ПубликацияТолько метаданныеMiniature x-ray emitters with carbon nanotube cathodes for radiotherapy(2019) Bratsuk, A. V.; Simonov, A. A.; Chesnokov, D. A.; Taubin, M. L.; Таубин, Михаил Львович© 2019 Author(s). This paper presents the results of development of miniature emitters of ionizing radiation for intracavitary and surface therapy of oncological deceases. The emitter can be placed close to the tumor in the organism and used for the purposes of gynecology, urology, proctology, mammology, etc.
- ПубликацияТолько метаданныеCold cathodes based on carbon nanotubes for the x-ray sources used in radiation therapy and diagnostics(2019) Bratsuk, A. V.; Simonov, A. A.; Taubin, M. L.; Таубин, Михаил Львович© 2019 Author(s). The goal of the work is to develop carbon nanotube (CNT) cold cathodes for X-ray tubes used for medical diagnostics and therapy. Within the scope of work cathodes with emissive layer formed of carbon nanotubes on their surface by CVD have been studied. Being the catalysts for CNT synthesis, nickel, cobalt and kovar were used as the substrate. X-ray dose rate dependences on voltage and emission current have been acquired. X-ray images of various objects have been taken.
