Abstract: Among the various aspects of the present disclosure is the provision of devices, systems, and methods for tracking the positions and orientations of at least one bone screw implanted within a surgical site. The disclosed device includes an extension that includes an extension base configured to couple to the bone screw, a marker arm coupled at one end to the extension base in a hinged arrangement, and an optical marker attached to a free end of the marker arm opposite the hinged attachment. The optical marker includes a pair of lenticular arrays in a coplanar arrangement in which the major axes of the lenticular arrays are mutually perpendicular. Each lenticular array is configured to display different hues at different viewing angles. The disclosed method includes transforming a single image of a surgical site containing at least one bone screw and extension into the global positions of each bone screw based on the pixel positions and hues corresponding to the lenticular arrays of each optical marker.

Abstract: A computer-implemented method for correcting artifacts within CT images of a subject includes providing iteratively correcting a CT volumetric image with a high-contrast mask by overpainting the high-contrast mask within CT volumetric image set by evaluating a model function and updating the CT projections to reflect the overpainting using a gradient descent based on previous overpainted CT projections, back-projecting the corrected CT projections to produce a corrected volumetric image set, and comparing the corrected CT volumetric image set against a previous corrected CT volumetric image set until convergence. The original voxels overpainted by the high-contrast mask are re-inserted into the converged CT volumetric image to produce the final CT volumetric image set.
Abstract: Among the various aspects of the present disclosure is the provision of methods to predict the risk of developing immunotherapy-associated neurotoxicity in a subject by measuring neurofilament light chain (NfL) levels in a biological sample obtained from the subject, wherein the subject is receiving or may receive an immunotherapy such as CAR T cell therapy.

Abstract: Low-pass whole genome sequencing, as well as targeted hybrid-capture next-generation sequencing, were performed to detect both small mutations and genome-wide copy number alterations to more precisely detect MRD after physician's-choice neoadjuvant chemotherapy. A machine learning model using both cell-free DNA and pre-treatment clinical characteristics is disclosed. With this method, it was possible to significantly predict both progression-free and overall survival.
