20090028399 | System and Method for Detecting Stripe Artifacts in MIP Rendered Images - A method for efficiently rendering a chessboard artifact free Maximum intensity projection (MIP) image is disclosed is disclosed. MIP is a widely used volumetric rendering technology in medical diagnostic imaging. When a volume dataset containing wideband noise is rendered using MIP, the resultant MIP image can show chessboard or stripe like artifacts. A method is disclosed for automatically detecting stripe artifacts present in the MIP rendered images and to determine whether suitable mitigation algorithms need to be applied during rendering. This automatic detection method eliminates the need for human review of images to determine whether mitigation is required, and thus speeds the overall process. | 01-29-2009 |
20110157344 | METHOD AND APPARATUS FOR FAST FOCUS IMAGING BIOLOGIC SPECIMENS - A method and apparatus for imaging a biologic fluid sample quiescently residing within a chamber is provided. The method includes the steps of: a) positioning the chamber at a Z-axis position relative to an objective lens having a lens axis, wherein the Z-axis is parallel to the lens axis; b) moving one or both of the chamber and the objective lens relative to one another at a velocity along the Z-axis; and c) creating one or more images of the biologic fluid sample as one or both of the chamber and the objective lens are moving at a velocity relative to one another within a focus search range along the Z-axis. | 06-30-2011 |
20110164803 | METHOD AND APPARATUS FOR DETERMINING MEAN CELL VOLUME OF RED BLOOD CELLS - A method and apparatus for determining a cell volume of a red blood cell is provided. The method includes the steps of: a) depositing a sample into an analysis chamber, the chamber defined by an first panel interior surface, a second panel interior surface, and a known or determinable height, which height is such that at least one red blood cell subject to a sphering agent assumes a partially compressed spherical shape in contact with the interior surfaces; b) imaging the at least one partially compressed spherical red blood cell contacting the interior surfaces, and producing image signals; c) determining a radius of the partially compressed spherical red blood cell from the image signals; and d) determining a volume of the imaged red blood cell using the determined radius. | 07-07-2011 |
