Methods and Algorithms For Cell Enumeration in a Low-Cost Cytometer

The enumeration of cells in fluids by flow cytometry is widely used across many disciplines such as assessment of leukocyte subsets in different bodily fluids or of bacterial contamination in environmental samples, food products and bodily fluids. For many applications the cost, size and complexity of the instruments prevents wider use, for example, CD4 analysis in HIV monitoring in resource-poor countries. The novel device, methods and algorithms disclosed herein largely overcome these limitations. Briefly, all cells in a biological sample are fluorescently labeled, but only the target cells are also magnetically labeled. In addition, non-magnetically labeled cells are imaged for viability in a modified slide configuration. The labeled sample, in a chamber or cuvet, is placed between two wedge-shaped magnets to selectively move the magnetically labeled cells to the observation surface of the cuvet. An LED illuminates the cells and a CCD camera captures the images of the fluorescent light emitted by the target cells. Image analysis performed with a novel algorithm provides a count of the cells on the surface that can be related to the target cell concentration of the original sample. The compact cytometer system provides a rugged, affordable and easy-to-use technique, which can be used in remote locations.

A system whose most common use is that of inspecting conduits such as sewers, drainage pipes, water, gas and oil conduits. Contrary to camera systems currently on the market, the system has individual components that are easily disconnected and reconnected so that a failed component can be determined and replaced in the field, yet it maintains its integrity against damage from the type of effluent in which it is required to operate. The system's control unit is easily disconnected and replaced, and is mounted on a carrier. The system includes a push rod assembly that has male or female plugs providing quick disconnects at each end so that it can readily be disconnected from opposite gender plugs on a rotary contact assembly at one end and a video camera assembly at its other end. The rotary contact assembly is mounted on the carrier and is similarly connected to and from the control unit, which is physically separate and is also mounted on the carrier. The carrier also has a reel on which the push rod assembly is stored. Electrical power is provided from a power source for the camera and the video equipment that receives video signals from the camera. The power source may or may not be mounted upon the carrier. The novel splices between the wires of various units and either a male or a female plug by which units are connected are a major contribution to the success of the invention. Similar splices can also be used for field repairs to damaged push rod assemblies or for increasing the overall length of the push rod assembly.
