Abstract[English]
A method of applying tumor treating fields to a torso of a subject's body, the method including: locating a first transducer at a first location of the subject's body, the first location being on the torso of the subject's body; locating a second transducer at a second location of the subject's body, the second location being below the torso of the subject's body; and inducing an electric field between at least part of the first transducer and at least part of the second transducer. Also provided is a system to apply tumor treating fields to a torso of a subject's body, the system comprising: a first transducer adapted to be located at a first location of the subject's body, the first location being on the torso of the subject's body; a second transducer adapted to be located at a second location of the subject's body, the second location being below the torso of the subject's body; a voltage generator adapted to be coupled to the first transducer and the second transducer and capable of providing first voltage to the first transducer and second voltage to the second transducer; and a controller coupled to the voltage generator, the controller comprising one or more processors and memory accessible by the one or more processors, the memory storing instructions that when executed by the one or more processors, cause the controller to instruct the voltage generator to generate the first voltage and the second voltage to induce an electric field in the torso of the subject's body, the electric field having field intensities of at least 1.0 V/cm in at least 50% of volume of the torso of the subject's body. A computer- implemented method to determine placement of transducers on a subject's body for inducing tumor treating fields, the computer comprising one or more processors and memory accessible by the one or more processors, the memory storing instructions that when executed by the one or more processors cause the computer to perform the method, the method comprising: selecting a plurality of pairs of locations on the subject's body, each pair of locations having a first location to locate a first transducer and a second location to locate a second transducer; obtaining a model of AC electrical conductivity in a portion of the subject's body; obtaining, for each location in the plurality of pairs of locations on the subject's body, an indication of heat removal potential at a surface of the subject's body; selecting one or more recommended pairs of first locations and second locations based at least on the model of AC electrical conductivity and the indication of heat removal potential for each location; and outputting the one or more recommended pairs of first locations and second locations.[French]
L'invention concerne un procédé d'application de champs de traitement de tumeur au torse du corps d'un sujet, le procédé comprenant : la localisation d'un premier transducteur à un premier emplacement du corps du sujet, le premier emplacement étant sur le torse du corps du sujet ; la localisation d'un second transducteur à un second emplacement du corps du sujet, le second emplacement étant au-dessous du torse du corps du sujet ; et l'induction d'un champ électrique entre au moins une partie du premier transducteur et au moins une partie du second transducteur.
