Our patient positioning routine comprises a novel robust dynamic fusion (RDF) algorithm for accurate 3D patient body modeling. ...
With its multi-modal inference capability, RDF can be trained once and used across different applications (without re-training) having various sensor choices, a key feature to enable system deployment ...
Much recent algorithmic work [7] - [9] in patient positioning has focused on estimating the 2D or 3D keypoint locations on the patient body. ...
