Radiotherapy couches: is kevlar an obstacle? Attenuation study of three differe...
Silva, Célia; Mateus, Dalila; Vieira, Sandra; Rodrigues, Milton; Eiras, Margarida; Greco, CarloIntroduction: Treatment tabletops are usually made of carbon fibre due to its high mechanical strength and rigidity, low specific density, extremely light and regularly considered radio translucent. Our clinic acquired a Calypso 4D Localization System where electromagnetic (EM) frequencies to detect implanted transponders in the patient are used. Carbon fibre is an electrical conductive material which interfere...
Comparação do movimento respiratório adquirido com TC 4D e com o sistema Calyps...
Costa, Sónia Oliveira; Sá, Ana Cravo; Mateus, Dalila; Marques, João; Coelho, Carina Marques; Monsanto, FátimaObjetivo do estudo - Comparar as amplitudes respiratórias segundo os eixos x, y e z adquiridos com a tomografia computorizada (TC) 4D e o sistema Calypso® em cancro de pulmão.
Calypso’s array attenuation
Silva, Célia; Mateus, Dalila; Vieira, Sandra; Rodrigues, Milton; Eiras, Margarida; Greco, CarloIntroduction: The Calypso 4D Localization System gives the possibility to track the tumour during treatment, with no additional ionising radiation delivered. To monitor the patient continuously an array is positioned above the patient during the treatment. We intend to study, for various gantry angles, the attenuation effect of the array for 6- and 10 MV and flattening filter free (FFF) 6- and FFF 10 MV photon ...
Calypso® 4D localization system: a review
Silva, Célia; Mateus, Dalila; Eiras, Margarida; Vieira, SandraPurpose: Calypso® 4D Localization System is a system based on electromagnetic transponders detection enabling precise 3D localization and continuous tracking of tumour target. This review intended to provide information in order to (1) show how Calypso® 4D Localization System works, (2) to present advantages and disadvantages of this system, (3) to gather information from several clinical studies and, finally, ...
