Patent number: 8676296Abstract: A dual-echo sequence technique provided herein empowers simultaneous acquisition of both TOF MRA and BOLD MRV in a single MR acquisition. By this approach, an echo-specific K-space ordering scheme permits the adjustment of the scan parameters that are compatible for each of the MRA and MRV. The image quality in the MRA and MRV acquired by this compatible dual-echo arteriovenography (CODEA) technique is comparable to that for conventional, single-echo MRA and MRV. When the technique is integrated with MOTSA, seamless vascular connectivity is achieved in both MRA and MRV over a large area of brain anatomy. The technique will facilitate routine clinical acquisition and application of dual-echo MRA and MRV, as both MRA and MRV can be acquired with minimal impact on the image quality and without adversely affecting the scan throughput.Type: GrantFiled: September 14, 2009Date of Patent: March 18, 2014Assignee: Univerity of Pittsburgh—Of The Commonwealth System of Higher EducationInventors: Sung-Hong Park, Kyongtae Ty Bae

Patent number: 7747063Abstract: In an embodiment of a method of inspecting a substrate, the substrate on which minute structures are formed is divided into a plurality of inspection regions. A main inspection region among the inspection regions is selected. A main image of the main inspection region and sub-images of sub-inspection regions adjacent to the main inspection region are obtained. An average image of the main image and the sub-images is obtained. The average image is then compared with the main image to detect defects in the main inspection region. Gray levels may be used. The average image may have improved quality so that the defects in the selected inspection region may be rapidly and accurately detected. This process has an improved reliability. Further, the number of inspecting processes for the substrate may be reduced. And a line for the inspection process may be automated so that a worker-free line may be established.Type: GrantFiled: August 8, 2006Date of Patent: June 29, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-Taek Lim, Chung-Sam Jun, Young-Jee Yoon, Sung-Hong Park

Patent number: 7626164Abstract: In an embodiment, a method of scanning a substrate, and a method and an apparatus for analyzing crystal characteristics are disclosed. A sequential scan on the scan areas using a first electron beam and a second electron beam are repeatedly performed. The electrons accumulated in the scan areas by the first electron beam are removed from the scan areas by the second electron beam. When a size of the scan area is substantially the same as a spot size of the first electron beam, adjacent scan areas partially overlap each other. When each of the scan areas is larger than a spot size of the first electron beam, the adjacent scan areas do not overlap each other. Images of the scan areas are generated using back-scattered electrons emitted from each of the scan areas by irradiating the first electron beam to analyze crystal characteristics of circuit patterns on the substrate.Type: GrantFiled: November 29, 2006Date of Patent: December 1, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Young-Jee Yoon, Jung-Taek Lim, Tae-Sung Kim, Chung-Sam Jun, Sung-Hong Park
