Patent number: 10575817Abstract: According to one embodiment, an ultrasound diagnosis apparatus transmits ultrasound waves to a subject from a plurality of transducers each corresponding to one of a plurality of channels, and receives reflected waves generated in the subject by the transducers. The ultrasound diagnosis apparatus includes a control circuit and a receiving circuit. The control circuit controls channels used to transmit ultrasound waves and channels not used to transmit ultrasound waves among the channels. The receiving circuit receives the reflected waves, and includes a preamplifier and an impedance control circuit. The preamplifier amplifies the reflected waves. The impedance control circuit is located on the upstream side of the preamplifier, and sets line impedance in a transmitting period, in which the ultrasound waves are transmitted from the transducers to the inside of the subject, to be lower than that in a receiving period, in which the reflected waves are received by the transducers.Type: GrantFiled: February 8, 2017Date of Patent: March 3, 2020Assignee: Canon Medical Systems CorporationInventors: Hiroyuki Shibanuma, Isao Uchiumi, Nobuyuki Iwama, Wataru Kameishi, Yuhei Fukuo

Patent number: 10564273Abstract: An ultrasonic diagnostic apparatus according to a present embodiment includes a transmission circuit, a reception circuit, a data processing circuit, an image generating circuit, a switching power supply circuit, and a control circuit. The switching power supply circuit is configured to generate a drive voltage for at least one of the transmission circuit, the reception circuit, the data processing circuit, and the image generating circuit. The control circuit is configured to control the transmission circuit to repeatedly transmit an ultrasonic pulse, and control a timing of a switching operation of the switching power supply circuit to synchronize the timing with a transmission timing or a reception timing of the ultrasonic pulse.Type: GrantFiled: August 25, 2016Date of Patent: February 18, 2020Assignee: Canon Medical Systems CorporationInventors: Nobuyuki Iwama, Yuhei Fukuo, Koichi Morikawa, Wataru Kameishi, Isao Uchiumi, Hiroyuki Shibanuma

Publication number: 20180333138Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes a processor. The processor generates assistance information to assist an operation of a puncture needle based on pressure information acquired from a pressure sensor attached to the puncture needle. The processor displays on a display the assistance information and an ultrasonic image which includes at least an image of a tip of the puncture needle, the ultrasonic image being acquired by transmission and reception of ultrasonic waves by using an ultrasonic probe.Type: ApplicationFiled: May 15, 2018Publication date: November 22, 2018Applicant: Canon Medical Systems CorporationInventors: Takatoshi OKUMURA, Kazutoshi SADAMITSU, Yuhei FUKUO, Norihisa KIKUCHI, Masatoshi NISHINO, Yoshinori GOTO, Naoki YONEYAMA

Publication number: 20160151039Abstract: According to one embodiment, an ultrasound diagnosis apparatus includes a transmitter, a receiver, a needle tip position acquisition unit, a ROI setting unit, an image generator, and a display controller. The transmitter transmits ultrasound beams to a subject into which a puncture needle is inserted while scanning the subject. The receiver receives signals reflected from the subject. The needle tip position acquisition unit successively acquires the position of the needle tip of the puncture needle. The ROI setting unit sets a region of interest at least in a direction in which the puncture needle is inserted. The image generator generates an image of the region of interest according to the position of the needle tip based on the signals. The display controller displays the image of the region of interest.Type: ApplicationFiled: November 25, 2015Publication date: June 2, 2016Applicants: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Koichi MORIKAWA, Isao Uchiumi, Nobuyuki Iwama, Toru Hirano, Hironobu Hongou, Yuhei Fukuo
