Patent number: 12206387Abstract: Surface acoustic wave resonators are disclosed. In certain embodiments, a surface acoustic wave resonator can include a high impedance layer, a piezoelectric layer over the high impedance layer, an interdigital transducer electrode over the piezoelectric layer, and a low impedance layer between the high impedance layer and the piezoelectric layer. An acoustic impedance of the high impedance layer is greater than an acoustic impedance of the piezoelectric layer. An acoustic impedance of the low impedance layer is lower than the acoustic impedance of the high impedance layer. The piezoelectric layer can have a cut angle in a range from 115° to 135°. The surface acoustic wave resonator is configured to generate a Rayleigh mode surface acoustic wave having a wavelength of ?.Type: GrantFiled: April 28, 2023Date of Patent: January 21, 2025Assignee: Skyworks Solutions, Inc.Inventors: Rei Goto, Keiichi Maki

Patent number: 10980498Abstract: A radiography apparatus sequentially determines, on the basis of the positions of markers as time-sequential feature points (of a plurality of frames), positions at which the markers in the frames are displayed. This makes it possible to display a moving object while the position, direction and size thereof are properly set. Another advantage is that when a plurality of markers are extracted, information relating to the direction and size of the object is retained and the proximal and distal directions of the object and the length of a device (e.g., stent) can be intuitively determined from an image. Since positioning is performed using the plurality of positions of markers and the plurality of display positions, the position and direction of a corrected image to be finally displayed can also be set properly.Type: GrantFiled: December 28, 2015Date of Patent: April 20, 2021Assignee: SHIMADZU CORPORATIONInventors: Shota Sato, Wataru Takahashi, Michel Dargis, Takihito Sakai, Keiichi Goto, Sebastien Matte

Patent number: 10856825Abstract: [Purpose] To provide a radiographic imaging apparatus capable of quickly acquiring three-dimensional image data of a target-of-interest when performing an operative procedure such as interventional treatment [Solving Means] A region-of-interest extraction unit 39 extracts a predetermined region as a region-of-interest from each of a series of two-dimensional images. The reconstruction unit 41 reconstructs a three-dimensional image of a region including a stent based on each of the images of the portion corresponding to the region-of-interest. That is, since the reconstruction unit 41 reconstructs each of a series of two-dimensional images P using an image of the region-of-interest corresponding to a part of the whole, the time required to reconstruct the three-dimensional image of the region including the stent can be shortened.Type: GrantFiled: March 16, 2018Date of Patent: December 8, 2020Assignee: Shimadzu CorporationInventors: Michel Dargis, Wataru Takahashi, Keiichi Goto

Patent number: 7940887Abstract: An X-ray tube and a flat panel X-ray detector (FPD) are constructed movable parallel to each other in the same direction along a body axis which is a longitudinal direction of a patient. The X-ray tube intermittently emits radiation and the FPD detects radiation transmitted through the patient irradiated intermittently whenever the X-ray tube and FPD move every pitch. X-ray images O1, O2, . . . , OI, . . . , and OM are decomposed for every pitch noted above. The decomposed images are composed for each projection angle to obtain projection images P1, P2 and so on. Therefore, a sectional image with a long field of view in the longitudinal direction can be obtained by carrying out a reconstruction process based on the composed projection images.Type: GrantFiled: August 8, 2007Date of Patent: May 10, 2011Assignee: Shimadzu CorporationInventors: Koichi Shibata, Kazuhiro Mori, Shingo Baba, Daisuke Notohara, Shinya Hirasawa, Keiichi Goto, Yukio Mishina
