Abstract
A transducer apparatus for delivering tumor treating fields to a subject's body, the transducer apparatus including: an array of electrode elements, the array configured to be positioned over the subject's body with a face of the array facing the subject's body; wherein, when viewed from a direction perpendicular to the face of the array, an outer perimeter of the array substantially tracing the electrode elements has a shape including: at least one convex edge portion protruding away from a centroid of the array; and at least one concave edge portion recessed toward the centroid of the array.
Claims19
A transducer apparatus for delivering tumor treating fields to a subject's body, the transducer apparatus comprising:
- an array of electrode elements, the array configured to be positioned over the subject's body with a face of the array facing the subject's body and to deliver tumor treating fields to the subject's body;
- wherein, when viewed from a direction perpendicular to the face of the array, an outer perimeter of the array traces the electrode elements and has a shape comprising:
- a centroid located within the outer perimeter of the shape;
- at least one convex edge portion protruding away from the centroid of the array;
- and
- at least one concave edge portion recessed toward the centroid of the array,
- wherein, when viewed from the direction perpendicular to the face of the array, the at least one convex edge portion and the at least one concave edge portion are complimentary shapes capable of fitting together adjacent to each other on a surface of the subject's body without overlapping each other,
- wherein, when viewed from the direction perpendicular to the face of the array, the outer perimeter of the array has a bow-tie shape, infinity symbol shape, peanut shell shape, or butterfly shape.
A transducer apparatus for delivering tumor treating fields to a subject's body, the transducer apparatus comprising:
- an array of electrode elements, the array configured to be positioned over the subject's body with a face of the array facing a subject's body and to deliver tumor treating fields to the subject's body;
- wherein, when viewed from a direction perpendicular to the face of the array, an outer perimeter of the array traces the electrode elements and has a shape comprising:
- a centroid located within the outer perimeter of the shape;
- at least one convex edge portion protruding away from the centroid of the array;
- and
- at least one concave edge portion recessed toward the centroid of the array,
- wherein, when viewed from the direction perpendicular to the face of the array, the outer perimeter of the array has a shape comprising at least two concave edge portions and at least two convex edge portions,
- wherein, when viewed from the direction perpendicular to the face of the array, the outer perimeter of the array has a bow-tie shape, infinity symbol shape, peanut shell shape, or butterfly shape.
