1. A method for imaging a volume of tissue and defining a boundary of the volume of tissue using an ultrasound transducer array comprising a set of emitter-receiver pairs, the method comprising: acquiring a baseline dataset and a reconstruction dataset with the ultrasound transducer array, wherein the baseline dataset is representative of a first set of signals interacting with a medium without the volume of tissue present in the medium and the reconstruction dataset is representative of a second set of signals interacting with the medium and the volume of tissue present in the medium; receiving the baseline dataset from the set of emitter-receiver pairs; receiving the reconstruction dataset from the set of emitter-receiver pairs; generating a set of similarity metrics, each similarity metric comparing a first metric of the baseline dataset, associated with an emitter-receiver pair from the set of emitter-receiver pairs, with a second metric of the reconstruction dataset, associated with the emitter-receiver pair; based upon the set of similarity metrics, determining a set of direct emitter-receiver pairs, wherein each direct emitter-receiver pair in the set of direct emitter-receiver pairs defines a direct trajectory that does not pass through the volume of tissue; from the set of direct emitter-receiver pairs, determining a set of tangential emitter-receiver pairs, wherein each tangential emitter-receiver pair in the set of tangential emitter-receiver pairs defines a bounding vector comprising a tangent point along the boundary; and transforming the reconstruction dataset into an image rendering, based upon reconstruction of a set of interior pixels of the reconstruction dataset, that are within the boundary.
