1. An apparatus for treating a target region in a subject'"'"'s body with TTFields, the target region being located in a portion of the subject'"'"'s body that has a longitudinal axis, the apparatus comprising:

  • a first set of one or more capacitively coupled electrodes;

    a first substrate configured to hold the first set of one or more electrodes against the subject'"'"'s body so that the first set of one or more electrodes surrounds a first part of the subject'"'"'s body at a position that is longitudinally prior to the target region;

    a second set of one or more capacitively coupled electrodes;

    a second substrate configured to hold the second set of one or more electrodes against the subject'"'"'s body so that the second set of one or more electrodes surrounds a second part of the subject'"'"'s body at a position that is longitudinally subsequent to the target region;

    a third set of one or more capacitively coupled electrodes;

    a third substrate configured to hold the third set of one or more electrodes against the subject'"'"'s body on a first side of the target region, at a position that is longitudinally between the first set of one or more electrodes and the second set of one or more electrodes;

    a fourth set of one or more capacitively coupled electrodes; and

    a fourth substrate configured to hold the fourth set of one or more electrodes against the subject'"'"'s body on a second side of the target region that is opposite to the first side, at a position that is longitudinally between the first set of one or more electrodes and the second set of one or more electrodes.
