Abstract: A method of analyzing a blood sample from a subject includes loading the blood sample into a single chamber; acquiring, via an imaging system, a stack of serial focal plane images of the blood sample from a plurality of fields of view of the chamber; creating a virtual three dimensional image of the blood sample from selected ones of the stacks of serial focal plane images; and analyzing the virtual three dimensional image to identify blood formed elements within the blood sample. Identifying blood formed elements within the blood sample may include identifying a type and amount of white blood cells, and/or identifying an amount of red blood cells and/or hematocrit, and/or identifying an amount of platelets. Identifying blood formed elements within the blood sample may include determining numbers and percentage by volume in the blood sample of one or more types of white blood cells.

Abstract: An electrode configured to adhere to a patient's skin to conduct electrical potentials therefrom includes a substrate, a skin adhesive configured to adhere the electrode to a patient's skin, and a conductor plate mounted on the substrate. A conductive gel is configured to contact the patient's skin and to conduct electrical potentials from the patient's skin to the conductor plate when the electrode is adhered to the patient's skin. A removable separator is positioned between the conductive gel and the conductor plate, wherein the removable separator is configured to be removed prior to operating the electrode to conduct electrical potentials.

Abstract: An X-ray imaging apparatus comprises a digital X-ray detector housed in a radiation shielded enclosure with multiple pinhole apertures in the front panel of the housing. An X-ray source illuminates a target and X-rays are backscattered towards the X-ray imaging apparatus. The multiple pinhole apertures arranged in a pattern so that each pinhole generates a respective pinhole image on the X-ray detector. The size of each image is controlled by the thickness of the front panel and the width of the pinhole aperture (acting as optical stops), and the distance to the X-ray detector, and these values are selected to prevent overlap between any pair of pinhole images on the X-ray detector. An image processor is used to generate a synthetic combined image of the object form the multiple pinhole images.
