Patent number: 10413270Abstract: According to one embodiment, a medical image diagnostic apparatus includes a holding device, a driving unit, a first encoder, a second encoder, and processing circuitry. The holding device holds an X-ray generator and an X-ray detector such that the X-ray generator and the X-ray detector are rotatable. The driving unit transmits a rotating force of a driving motor to a rotation axis through a power transmission mechanism. The first encoder detects a rotation of the driving motor. The second encoder detects a rotation of the rotation axis. The processing circuitry detects an abnormal state of the power transmission mechanism, based on a time difference between a first pulse output from the first encoder and a corresponding second pulse output from the second encoder.Type: GrantFiled: November 14, 2017Date of Patent: September 17, 2019Assignee: Canon Medical Systems CorporationInventors: Koji Noda, Tsuyoshi Kojima, Toshio Muroi, Shinji Nishizawa, Yoshihito Abe, Junko Shibata

Patent number: 8267867Abstract: An ultrasound image diagnosis apparatus and a method for setting an ultrasound drive voltage by which appropriate probe motion parameters are established by individually estimating temperature changes which occur due to a plurality of heat sources existing within the probe. By individually storing or correcting relative temperature change data associated with motion parameters due to a plurality of heat source elements, an optimum driving voltage for the ultrasound transducers is set. Since a transmission drive voltage is larger than the conventional drive voltage can be set under a permissible probe temperature, image diagnosis can be improved.Type: GrantFiled: March 10, 2011Date of Patent: September 18, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Yoshihito Abe, Tomohisa Imamura
