    Abstract: An apparatus that configures a culture plate for precisely assigning coordinates to a selected colony by assigning fiducials to the culture plate using simple mechanical techniques. The fiducials correspond to the plate center and the center of a barcode label applied to the side of the culture plate by the apparatus. The apparatus then deploys mechanisms to apply coordinates to colonies identified by the user relative to the fiducials. One such mechanism is a webcam pointed at the culture plate that allows a technician to mark the colonies on a display using a computer mouse or equivalent cursor. Another mechanism deploys a laser pointer directed at the colony wherein the apparatus assigns coordinates to the location of the colony onto which the laser pointer is directed. In a third mechanism, the user views the surface of the culture plate through a viewfinder and manually registers coordinates when the view finder cross hairs are over a target colony. The selected colonies are assigned precise coordinates with reference to the two fiducials. Software is provided such that pixels in the image of the culture plate correspond to the coordinates of the culture dish relative to the fiducials.

    Abstract: An imaging system and method provides automated microbial growth detection for antibiotic sensitivity testing. A processing system having an image sensor for capturing images of an inoculated culture plate having antibiotic disks disposed on the culture media captures images of the plate at separate times (e.g., first and second images). The system generates pixel characteristic data for pixels of the second image from a comparison of the first image and second image. The pixel characteristic data may be indicative of plate growth. The system may access growth modeling data concerning the antibiotic disk(s) and generate simulated image data with a growth model function. The growth model function uses the growth modeling data. The simulated image data simulates growth on the plate relative to the disk(s). The system compares the simulated image and the pixel characteristic data to identify pixel region(s) of the second image that differ from the simulated image.
