Patent number: 5724976Abstract: Provided is a diagnostic ultrasound system producing an image whose brightness is enhanced by a contrast medium by implementing contrast echography based on intravenous injection. A diagnostic ultrasound system comprises a probe for converting an electrical driving signal into a corresponding transmission ultrasound wave and converting an echoed ultrasound wave into a corresponding electrical echo signal. The system still comprises a unit for transmitting the transmission ultrasonic wave to a subject by providing the probe the electrical driving signal substantially consisting of a fundamental component of a given driving frequency. The non-fundamental component is typically a second harmonic. A non-fundamental component of the driving frequency is intentionally lowered in power relative to the fundamental component by a suppressing element in the transmitting unit.Type: GrantFiled: December 27, 1995Date of Patent: March 10, 1998Assignee: Kabushiki Kaisha ToshibaInventors: Yoshitaka Mine, Makoto Hirama, Hiroyuki Tsujino, Shiroh Saitoh

Patent number: 5515857Abstract: A bloodstream velocity image is formed by scanning a two-dimensional region including a blood vessel in a body to be examined with an ultrasonic wave. A velocity profile is formed by distributing either one of average velocities and maximum velocities of bloodstream velocities at a plurality of positions arranged along a first direction, along a second direction which is perpendicular to the first direction and extending across the blood vessel. A bloodstream volume is calculated from the velocity profile and a blood vessel diameter. Thus, an error caused by movement of a blood vessel accompanying pulsation can be decreased.Type: GrantFiled: June 28, 1994Date of Patent: May 14, 1996Assignee: Kabushiki Kaisha ToshibaInventors: Hiroyuki Tsujino, Eiichi Shiki
