Research ArticleOpen accessPhrase in the titleThe Existing Methods for Motion Control of Flexible Needles along a Curved Path as Part of Robotic Systems for BrachytherapyAleksandr Vitaljevich Lopota, Nikolai Anatoljevich Gryaznov, Olga Valerjevna Velichko et al.Review of the recent developments in steerable needles and control algorithms of their movements in curvilinear directions in the human body for the modern robotic system to perform brachytherapy in prostate cancer patients is presented. Advantages of steerable needles over the standard ones are described; design aspects of these needles and results of the phantom studies are discussed. Scientific novelty … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 22 Jan 2016 · 7,488 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCalculating Curved Needles Deformation in Automated High-Dose Rate Brachytherapy OperationsNikolai A. Gryaznov, Olga V. Velichko, Konstantin Yu. Senchik et al.The article outlines the approach to applying the mechatronic technologies and robotic systems in carrying out the brachytherapy operations. To calculate the elastic state of the flexible needles of different geometry in the prostate model, a mathematical model of the flexible needle deformation has been applied which took into account the medium reaction and was based on the theory of … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 30 Mar 2016 · 7,333 accessesView PDF Cite
