Medical Imaging: Petri plate calibration

Although automation is widely used in clinical chemistry, hematology and immunology laboratories, the microbiology laboratory has only recently adopted automation.

Automation of the clinical microbiology laboratory is a multifunctional process, including the incubation and imaging of inoculated cultures on plates. The end-user is now assessing an image instead of a physical plate in order to perform a presumptive identification.

Currently, there is no agreement among manufacturers on the way to handle these Petri plate images from a color acquisition and a visualization perspective.

Proposal

Interested parties should develop a proposal for assessing Petri plate readers and display management.

The following activities are included:

Establish a measurement setup and associated protocol in order to allow the spectral characterization of inoculated plates, in both reflectance and transmittance.
Establish a common control colorimetric method to asses the color image quality of a Petri plate reader system
Propose a unified display management framework for Petri plate images (color and potentially multispectral).
