Insulated ceramic arrays Explanation: To evaluate the absorption of the RT energy by TTFields transducer arrays – insulated ceramic arrays with hydrogel – identical to those in the Novo-TTF100A system used for the treatment of GBM patients – were placed on a solid-state phantom. The surface-to-source distance was 100 cm; field size was set to 10 × 10 cm. Dosimetry was assessed using a PTW Unidos Markus plane parallel ion chamber for high-energy electron measurements in solid-state phantoms (RPD Inc., Albertville, Minnesota, USA) connected to a PTW Unidos Webline (RPD inc, Albertville, Minnesota, USA). Doses of 2 Gy were applied using a 6 MV photon beam (Elekta Precise linear accelerator, Elekta Oncology Systems, Stockholm, Sweden) and dosimetry at the depths of 0, 20 and 60 mm below the arrays were measured. Absorption of the RT energy was tested perpendicular to the surface and other angles of attack were not evaluated. -------------------------------------------------- Note added at 5 mins (2020-08-05 00:44:13 GMT) -------------------------------------------------- insulated ceramic discs Sorry for typo -------------------------------------------------- Note added at 5 mins (2020-08-05 00:44:47 GMT) -------------------------------------------------- https://cjon.ons.org/cjon/20/5/supplement/optune-practical-n... Optune is a portable device that delivers alternating electric fields, termed TTFields. Transducer arrays with insulated ceramic discs are connected to the device and strategically placed on the patient’s head to deliver the treatment. Optune consists of an electric field generator, a rechargeable battery pack, a power supply, and disposable ceramic discs, or arrays. Novocure filed with the FDA for approval of second-generation Optune, which was granted on July 13, 2016. The second-generation system is about 50% lighter at 2.7 pounds and has many advanced features to facilitate convenience of portability (see Figure 1). -------------------------------------------------- Note added at 6 mins (2020-08-05 00:45:30 GMT) -------------------------------------------------- You can use (arrays) for your question regarding المصفوفات https://ro-journal.biomedcentral.com/articles/10.1186/s13014-017-0941-6 |
