    Abstract: Provided herein as a guidewire controller cassette for positioning a guidewire within a patient body, including a housing having an interior space; a translational module received within the interior space and having an entry side, an opposed exit side and a lateral wall being disposed therebetween, the translational module comprising a first guidewire path extending between the entry side and the exit side and configured to move the guidewire translationally along the first guidewire path; and a rotational module received within the interior space and mounted at the lateral wall, the rotational module comprising an opening for receiving the proximal end of the guidewire, a rotating axis allowing the proximal end of the guidewire being rotated thereabout, and a second guidewire path which is a loop path extending out from the opening to the entry side.

    Abstract: Methods for correcting one or more image aberrations in an electron microscopy image, including cryo-EM images, are provided. The method includes obtaining a plurality of electron microscope (EM) images of an internal reference grid sample having one or more known properties, the plurality of electron microscope images obtained for a plurality of optical conditions and for a plurality of coordinated beam-image shifts. The method may also include, among other features, determining an aberration correction function that predicts aberrations for every point in the imaged area using kernel canonical correlation analysis (KCCA).
