1. A method of generating a digital model of a custom surface brachytherapy applicator, the method comprising:
a) obtaining an initial digital surface brachytherapy applicator model, wherein the initial digital surface brachytherapy applicator model comprises a patient-facing surface;
b) identifying a cut plane for bisecting the initial digital surface brachytherapy applicator model;
c) processing the initial digital surface brachytherapy applicator model to incorporate a plurality of catheter channels, thereby obtaining a modified digital surface brachytherapy applicator model, wherein the plurality of catheter channels are incorporated such that:
a first set of catheter channels are spatially distributed, relative to the cut plane, on a first side of the cut plane; and
a second set of catheter channels are spatially distributed, relative to the cut plane, on a second side of the cut plane;
wherein the cut plane is identified by:
processing the initial digital surface brachytherapy applicator model to determine, for each trial cut plane of a plurality of trial cut planes, a curvature measure associated with a curve defined by an intersection of the trial cut plane with the patient-facing surface of the initial digital surface brachytherapy applicator model; and
selecting the trial cut plane for which the curvature measure satisfies curvature criteria.
