Abstract: A method and system provide for augmenting a photograph. An unlabeled photograph is obtained. A weakly augmented photograph and a strongly augmented photograph are obtained from the unlabeled photograph based on different types of data augmentation methods. The weakly augmented photograph is processed through a model to generate multiple weakly augmented photograph class predictions (with assigned probabilities). The multiple weakly augmented photograph class predictions are converted into positive pseudo-labels (indicating a presence of a class) or negative pseudo-labels (indicating absence of a class) using different fixed percentile thresholds. The strongly augmented photograph is processed through the model to generate a strongly augmented photograph class prediction. The model is trained to make the strongly augmented photograph label prediction match the positive pseudo-label via a cross-entropy loss. The trained model is then utilized to label the unlabeled photograph with multiple labels.

Abstract: A cooling system of a computed tomography (CT) system provides for a more efficient operation than known heretofore. The cooling system of the CT system includes a gantry and a table that moves an object into a bore of the gantry. The gantry includes part boxes mounted therein, and blade elements are formed in regions of the part boxes. The cooling system of the CT system includes a cooling method that includes a multiple cooling method including a stand-by mode and an operating mode.

Abstract: A gantry of a computed tomography (CT) apparatus includes a rotating frame configured to rotate around a rotation axis and a rotation driver configured to rotate the rotating frame. The gantry also includes a stator configured to support the rotating frame while the rotating frame rotates and electronic components arranged along a circumferential direction of the rotating frame. The rotating frame includes a plurality of annular frames positioned concentrically around the rotation axis and a plurality of rib frames arranged on circumferential surfaces of the plurality of annular frames and parallel to the rotation axis in such a manner as to connect the plurality of annular frames. At least one of the plurality of annular frames and the plurality of rib frames has a recessed portion along a longitudinal direction thereof.

Abstract: A computed tomography (CT) system having a cooling system includes: a gantry unit, including a rotor and an assembly component; an intake provided on a first surface of the rotor; and an outtake provided on a second surface opposite to the first surface of the rotor; wherein the gantry unit is cooled by air moving through the intake and the outtake due to a rotation force or a centrifugal force generated by a rotation movement of the rotor.

Abstract: Cooling systems of a CT system and methods of cooling the CT system are disclosed. The CT system includes a gantry and a table that moves an object into a bore of the gantry, wherein the gantry includes a cover having a front surface in which at least an inlet slot is formed and a rear surface in which exhaust holes are formed along with exhaust fans in the rear surface of the cover of the gantry. Fans for the in-take and exhaustion of air are not required to be formed on the front surface of the cover of the gantry. A hole through which external air is taken in through the inlet slot is moved in a rotor of the gantry.

Abstract: Provided is an ultrasound diagnosis apparatus cooling system including: a case configured to contain hardware components for operating an ultrasound diagnosis apparatus; a cooler located in a first direction with respect to the case and configured to cause air to flow in the first direction in the case; and an air distribution layer located between the case and the cooler and configured to direct air from the case to the cooler.
