Patent number: 8891844Abstract: A time synchronization calibration method and system for image taking and coordinate reading and a delay time calculation method thereof are disclosed. The time synchronization calibration method is as follows. Firstly, every time point, a calibrator coordinate, an operation target coordinate and an image thereof are obtained. The image similarity index of every image and the image of previous time point thereof is calculated. When the image similarity index is lower than a preset similarity index, a reading time of the image is output followed with calculating the difference of the reading time and a time delay to obtain a taking time of the image. Finally, calculating the coordinate transformation of the calibrator coordinate and the operation target coordinate, and corresponding it to the image to output an image-coordinate correspondence relation. The time delay can be obtained correctly with only one test, and provided for the consequent synchronization calibration.Type: GrantFiled: March 8, 2013Date of Patent: November 18, 2014Assignee: National Central UniversityInventors: Ching-Shiow Tseng, Alex Tse, Chih-Ju Chang

Patent number: 8768023Abstract: A method for determining an axial direction of a bore of a bone fixator includes the following steps: obtaining X-ray images of the bore, calculating perpendicular bisectors, determining spatial planes, and obtaining the axial direction of the bore. After X-ray images of the bore are taken from two X-ray source positions, two overlapping images of the bore are obtained for calculating two perpendicular bisectors therein respectively. Each perpendicular bisector and its corresponding X-ray source position define one spatial plane. The intersection of the two spatial planes defines the axial direction of the bore. Now that the axial direction of the bore can be derived from only two X-ray images of the bore taken during an orthopedic surgery, radiation exposure of the patient and of the medical personnel involved can be significantly reduced.Type: GrantFiled: November 16, 2012Date of Patent: July 1, 2014Assignee: National Central UniversityInventors: Ching-Shiow Tseng, Pei-Chun Chen, Hung-Kang Wu
