    Abstract: Described herein are biomimetic Janus particles useful as artificial antigen presenting cells capable of activating T cells in vitro. “Bull's eye” ligand patterns mimicking either the native or reverse organization of the T cell immunological synapse are provided on the surface of nano- or micro-sized particles. Methods for activating T cells in vitro using biomimetic Janus particles described herein are also provided. T cells activated by the biomimetic Janus particles can be used in adoptive immunotherapies for treating cancer, tolerance induction in autoimmune disease, autologous immune enhancement therapy, and viral infection immunotherapy. Also described herein are methods for producing a biomimetic Janus particle.

    Abstract: A computing device is provided having at least one processor (104) operative to facilitate motion correction in a medical image file (102). The at least one processor (104) is configured to generate at least one unified frame file (110) based on motion image data (204), depth map data (206) corresponding to the motion image data, and region of interest data (200). Further, at least one corrected image file derived from the medical image file (102) is generated by performing the motion correction based on the at least one unified frame file (110) using the processor (104). Subsequently, the at least one corrected image file is outputted for display to one or more display devices (122).
