| 20080314114 | FLUORESCENCE CALIBRATOR FOR MULTIPLE BAND FLAT FIELD CORRECTION - A fluorescence reference plate for a fluorescence spectroscopic instrument is arranged with fluorescent layers having different excitation and emission characteristics. The fluorescent layers are ordered in the form of a stack for providing a flat-field calibration standard over multiple bands of wavelengths. | 12-25-2008 |
| 20090067582 | IMAGING TARGET FOR TESTING QUALITY OF MULTIPLE-MAGNIFICATION FOCUS AND IMAGE CO-REGISTRATION - An imaging target, suited for use in multi-modal imaging systems, includes test patterns for testing quality of both focus and co-registration for multiple magnifications and multiple modalities of operation of a multimodal imaging system. | 03-12-2009 |
| 20090080608 | METHOD AND APPARATUS FOR MEASURING LONG BONE DENSITY OF SMALL-ANIMALS - A method and apparatus are disclosed for measuring long bone density of small animals. A phosphor screen or plate is provided of a type that transduces incident ionizing radiation to emitted light. A small animal is positioned before the phosphor screen or plate and exposed to soft X-radiation having an energy level in the range of 11 to 16 Kev. Light emitted by the phosphor screen or plate is captured using a digital camera and a digital X-ray image is prepared of a long bone of the animal. The X-ray image is transformed into an X-ray density image and a region of interest is defined on the long bone in the X-ray density image. At least one row of pixels is scanned within the region of interest of the X-ray density image. A nonlinear least squares analysis of data obtained from the scanning step is conducted using a cylindrical model for the long bone within the region of interest. | 03-26-2009 |
| 20090273944 | VARIABLE CONDENSER FOR DELIVERY OF ILLUMINATION INCLUDING RECURSIVELY NESTED CIRCLE-TO-LINE FIBER OPTIC CONVERTER CABLE - A variable condenser for delivery of illumination, including a recursively nested circle-to-line fiber optic shape-converting cable and a focusable input lens system. At the input of the fiber optic cable, sets of individual optical fibers comprise successively smaller annuli recursively nested about a common center. At the output of the fiber optic cable, the sets of individual optical fibers comprise pairs of line segments recursively nested about the line midpoint, whereby the nesting level of the pairs of line segments has an exact or an approximate correspondence to the nesting level of the annuli. The output may be split into a plurality of lines, whereby the sets of individual optical fibers are distributed among the plurality of lines. The input lens system has a single adjustable focus means to vary the radius of an illumination spot incident upon the input of the fiber optic cable circle input. | 11-05-2009 |
| 20100022866 | TORSIONAL SUPPORT APPARATUS AND METHOD FOR CRANIOCAUDAL ROTATION OF ANIMALS - A torsional support apparatus is disclosed for craniocaudal rotation of test animals to enable multiple-view imaging. The animal is supported in a U-shaped loop of optically transparent material and the loop is moved to apply torsion to the animal to rotate it about its craniocaudal axis. Methods of imaging also are disclosed that use the torsional support technique. | 01-28-2010 |
