1. A method for determining placement positions for transducer arrays on a subject's body for applying tumor treating fields, the method comprising:
determining, by a processor and based on two-dimensional (2D) image data associated with a portion of a subject's body, one or more landmarks and one or more skin surface conditions, wherein the 2D image data is based on an exterior view of the subject's body obtained by a user device;
determining, by the processor, a representation of the one or more landmarks and the one or more skin surface conditions in three-dimensional (3D) space based on the one or more landmarks and one or more skin surface conditions determined from the 2D image data;
determining, by the processor and based on the representation of the one or more landmarks, the one or more skin surface conditions in 3D space, and a tumor location in the subject's body, a plurality of placement positions for one or more transducer arrays on the subject's body for applying tumor treating fields to the tumor location in the subject's body;
determining, by the processor and based on the one or more skin surface conditions in 3D space, one or more recommended placement positions of the plurality of placement positions for the one or more transducer arrays; and
outputting, by the processor, an indication of the one or more recommended placement positions for the one or more transducer arrays.
