Patent number: 9535247Abstract: Interferometric focusing (IF), rather than conventional geometric focusing, of excitation light onto a guide-star that is embedded deeply in tissue, increases its fluorescence intensity. The method can extend the depth of wavefront measurement and improve correction inside of tissues because of its ability to suppress both scattering of diffuse light and aberration of ballistic light. The results showed more than two times improvement in SNR and RMS error of the wavefront measurement. Although only ballistic light in the excitation path is corrected, the intensity after wavefront correction increased by 1.5 times. When applying IF to a two-photon microscope with a near infra-red laser, this method would further extend the measurement depth and achieve high SNR for the wavefront sensor.Type: GrantFiled: May 27, 2016Date of Patent: January 3, 2017Assignee: The Regents of the University of CaliforniaInventors: Xiaodong Tao, Joel A.

Patent number: 8369600Abstract: The present techniques provide systems and methods for registering images of tissue spots on a tissue microarray (TMA). In studies involving multiple biomarkers being studied on the same TMA, the TMA slide is removed from the microscope, stained, and then imaged, often multiple times.

Patent number: 8274721Abstract: A variable view imaging system for observation of micro object with variable view orientation and position includes a telecentric lens group, a scanning mirror, wedge prisms, a deformable mirror and related optical elements. The combination of a scanning mirror and a telecentric lens group decouples the motion of scanning mirror and the view angle. The view angle is determined only by the angle of the wedge prisms. This design increases the zenith angle of the view and simplifies the kinematics of the system. The wedge prisms and the scanning mirror can supply a flexible view in a compact way. The wavefront error induced by the wedge prisms is corrected by the deformable mirror. In order to achieve the desired view state during operation, the scanning mirror angle and the wedge prisms angle are calculated iteratively based on the kinematics and Jacobian matrix of system.Type: GrantFiled: March 3, 2009Date of Patent: September 25, 2012Assignee: Korea Advanced Institute of Science and Technology (Kaist)Inventors: Hyungsuck Cho, Xiaodong Tao

Patent number: 8238642Abstract: A method for determining 3D distances on a 2D pixelized image of a part or object includes acquiring a real 2D pixelized image of the object, creating a simulated image of the object using the 3D CAD model and the 2D pixelized image, determining a specified cost function comparing the simulated image with the real 2D pixilated image and repositioning the simulated image in accordance with iterated adjustments of a relative position between the CAD model and the 2D pixilated image to change the simulated image until the specified cost function is below a specified value. Then, the workstation is used to generate a 3D distance scale matrix using the repositioned simulated image, and to measure and display distances between selected pixels on a surface of the real image using 2D distances on the 2D pixelized image of the object and the 3D distance scale matrix.Type: GrantFiled: November 20, 2008Date of Patent: August 7, 2012Assignee: General Electric CompanyInventors: Yanyan Wu, Donald Robert Howard, Harry Israel Ringermacher, Robert August Kaucic, Zhaohui Sun, Francis Howard Little, Xiaodong Tao, Patrick Joseph Howard, Matthew Edward Dragovich, Eric Scott Foster

Patent number: 8189884Abstract: The present techniques provide fully automated methods for quantifying the location, strength and percent of expressed target molecules or other biological markers in immunohistochemically stained biological samples. The samples may be automatically segmented, for example into subcellular compartments, from images of compartmental markers. Then, the distribution of a target molecule on each of these compartments is calculated that includes the percentage and strength of expression. This is different than existing intensity or ratio based methods where abundant low expression levels are indistinguishable from scarce high expression levels.Type: GrantFiled: March 26, 2008Date of Patent: May 29, 2012Assignee: General Electric CompanyInventors: Ali Can, Michael John Gerdes, Musodiq Olatayo Bello, Xiaodong Tao
