The Paul Scherrer Institute (PSI/Switzerland) is developing, within the PROSCAN project, a new method of proton radiotherapy for treating cancers using a gantry based spot scanning technique for irradiating deep-seated tumors. Among the innovative elements are the laminated magnets in the beam lines, including the newly conceived Gantry 2, that will enable rapid energy changes (<150 ms) to modulate...
The recently proposed exothermic chemical reaction based tumor hyperthermia method presented a new way of realizing truly minimally invasive treatment for tumor. This method utilizes heat generated from the reaction between acid and alkali solutions to allow for tumor ablation. Successful clinical implementation of this method requires a clearer understanding and quantification of the ablation area...
A technique for steering of flexible bevel-tipped needles through tissue, providing proportional control of trajectory curvature by means of duty-cycled rotation or spinning during insertion, has been presented previously, and tested in vitro in gelatin samples. The present paper presents the results of testing under more authentic conditions. Thirty-two needle insertions were performed in cadaver...
The authors propose to build equipment for hyperthermia which could be utilized together with radiotherapy or chemotherapy in the treatment of mammary gland cancer and dermic carcinoma. The project consists of three parts: the first was the design, development, and construction of the equipment; the second, taking place now, is experimentation with animals and phantoms, the third will be the application...
