Patent number: 11660075Abstract: According to one embodiment, an ultrasound diagnosis apparatus includes a transmission beam former and a transmitting circuit. The transmission beam former generates a transmission pulse. The transmitting circuit supplies an ultrasound transducer with the transmission pulse received from the transmission beam former as a drive signal. The supply of a clock necessary for the generation of the transmission pulse is stopped during a substantial reception period of echo signals from the ultrasound transducer.Type: GrantFiled: December 15, 2017Date of Patent: May 30, 2023Assignee: Canon Medical Systems CorporationInventor: Teruki Hagihara

Patent number: 11129595Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes at least a memory circuitry, a processing circuitry, a data interpolation circuitry, and an image generating circuitry. The memory circuitry stores a plurality of pieces of reception data in an order of reception, the plurality of pieces of reception data being received continuously in a time series by a plurality of transducers, and specifies reading positions in an order different from the order of reception. The processing circuitry calculates a delay time, and calculates, based on the delay time, reading positions for acquiring reception data being used for calculating interpolation data from the memory circuitry. The data interpolation circuitry calculates interpolating data based on the plurality of pieces of reception data acquired from the calculated reading positions of the memory circuitry. The image generating circuitry generates an ultrasonic image based on a reception beam formed by using the interpolation data.Type: GrantFiled: October 22, 2015Date of Patent: September 28, 2021Assignee: Canon Medical Systems CorporationInventors: Teruki Hagihara, Wataru Kameishi, Hiroyuki Shibanuma, Masaaki Ishitsuka, Shuta Fujiwara, Satoshi Kamiyama, Tomohiro Fujita

Patent number: 10624606Abstract: An ultrasound diagnostic apparatus according to a present embodiment includes driving pulse generating circuitries and a transmission control circuitry. The transmission control circuitry turns on a switching element of respective driving pulse generating circuitries of the driving pulse generating circuitries to be grounded, and thereby controls so as to make an output impedance of the respective driving pulse generating circuitries become a low impedance. The transmission control circuitry turns off the switching element of the respective driving pulse generating circuitries, and thereby controls so as to make the output impedance become a high impedance by means of a resistance value of the resistance.Type: GrantFiled: December 21, 2015Date of Patent: April 21, 2020Assignee: Canon Medical Systems CorporationInventors: Wataru Kameishi, Hiroyuki Shibanuma, Satoshi Kamiyama, Masaaki Ishitsuka, Tomohiro Fujita, Teruki Hagihara, Shuta Fujiwara

Publication number: 20180368806Abstract: According to one embodiment, the ultrasonic diagnostic apparatus includes a main body housing, an arm, a device, a table, and an avoiding mechanism. The arm is mounted to the main body housing so as to be capable of ascending and descending and pivotable about a predetermined axis. The device is supported by the arm so as to be capable of ascending and descending and pivotable according to the movement of the arm. The table has a surface which is positioned in a descending direction of the arm and the device, and an object is placed on the surface. The avoiding mechanism changes a relative position between the object and a support position of ascending and descending movement of the arm such that interference between the object and at least one of the arm and the device due to the descending movement of the arm is avoided.Type: ApplicationFiled: June 21, 2018Publication date: December 27, 2018Applicant: CANON MEDICAL SYSTEMS CORPORATIONInventors: Shingo TOYODA, Hideo Onodera, Shinichiro Kikuchi, Teruki Hagihara, Tomohiro Fujita

Patent number: 10123777Abstract: An ultrasound diagnosis apparatus includes a transformer, a first power source, a second power source, and a switching unit. The transformer includes a primary winding and a secondary winding, and drives an ultrasound transducer based on a voltage generated in the secondary winding. The first and second power sources cause a potential difference. The switching unit switches a connection path between the primary winding and at least one of the first and second power sources to a first connection path that connects the first power source to one end of the primary winding and the second power source to the other end, a second connection path that connects the first power source to the other end and the second power source to the one end, or a ground connection path that connects the first power source or the second power source to the ground through the primary winding.Type: GrantFiled: December 21, 2015Date of Patent: November 13, 2018Assignee: Toshiba Medical Systems CorporationInventors: Wataru Kameishi, Hiroyuki Shibanuma, Shuta Fujiwara, Satoshi Kamiyama, Takayuki Shiina, Masaaki Ishitsuka, Tomohiro Fujita, Teruki Hagihara
