Abstract: Provided are methods of making and using pre-lithiated cathodes for use in lithium ion secondary cells as the means of supplying extra lithium to the cell. The chemically or electrochemically pre-lithiated cathodes include cathode active material that is pre-lithiated prior to assembly into an electrochemical cell. The process of producing pre-lithiated cathodes includes contacting a cathode active material to an electrolyte, the electrolyte further contacting a counter electrode lithium source and applying an electric potential or current to the cathode active material and the lithium source thereby pre-lithiating the cathode active material with lithium.

In some embodiments, an apparatus includes a sample bag defining an inner volume configured to receive a biological tissue sample, and a sealing member coupled to the sample bag. An imaging window is disposed and configured to be placed in contact with at least a portion of the biological tissue sample, and a positioning member is coupled to the imaging window and is configured to be disposed against the sealing member to substantially seal the inner volume. The positioning member includes a vacuum port disposed and configured to be aligned with a vacuum source to withdraw air from the inner volume of the sample bag.

Abstract: Medical imaging data can include imaging data of tissue portions, such as, for example, tissue samples. A processor is configured to receive imaging data obtained from imaging tissue. The imaging data includes a two-dimensional scan of tissue, such as, for example, a B-scan. The processor is configured to analyze the imaging data, and to identify imaging data associated with suspicious areas. The processor is configured to generate a visual interface that displays the imaging data associated with the suspicious areas in a stitched view. The processor, via the visual interface, enables a user to navigate to locations in the two-dimensional scan that correspond to imaging data associated with suspicious areas that the user determines to be positive for a characteristic (e.g., cancer).

Abstract: A system includes an imager configured to acquire at least one image of a tissue, a memory configured to store processor executable instructions, and a processor operably coupled to the imager and the processor. Upon execution of the processor executable instructions, the processor is configured to train a convolutional neural network (CNN) using a plurality of training images, and implement the CNN to determine a probability of abnormality of at least one region of tissue in the at least one image.

Abstract: Various embodiments are described herein for a system and method of integrated X-ray imaging and microscopic imaging of an imaging area having a sample on a sample stage. An X-ray apparatus may be disposed within the imaging area and be configured to acquire X-ray image data of at least a portion of the sample.

Abstract: A method and system for registering an imaging system to a sample container include a sample container configured to support a biological tissue sample and an imaging system for generating optical images of the biological tissue sample. The sample container includes an imaging window having a top surface in contact with the biological tissue sample and a bottom surface. The imaging system includes a scanning area that receives a portion of the sample container and an imaging device disposed below the scanning area. The imaging device emits a focused sample light signal towards the imaging window and receives a reflected sample light signal from the imaging window. By scanning the focal point of the sample light signal and measuring the reflected sample light signal, the location of the top surface of the imaging window can be determined, thus registering the imaging device to the imaging window of the sample container.
