Patent number: 7838838Abstract: An imaging system is provided for radioimaging a region of interest (ROI) of a subject. The system includes a housing, a support structure, which is movably coupled to the housing, and at least one motor assembly, coupled to the housing and the support structure, and configured to move the support structure with respect to the housing. The system also includes at least two detector assemblies, fixed to the support structure, and comprising respective radiation detectors and angular orientators. A control unit drives the motor assembly to position the support structure in a plurality of positions with respect to the housing, and, while the support structure is positioned in each of the plurality of positions, drives the orientators to orient the respective detectors in a plurality of rotational orientations with respect to the ROI, and to detect radiation from the ROI at the rotational orientations. Other embodiments are also described.Type: GrantFiled: September 17, 2009Date of Patent: November 23, 2010Assignee: Spectrum Dynamics LLCInventors: Benny Rousso, Shlomo Ben-Haim, Haim Melman, Michael Nagler, Yoel Zilberstien, Sajed Haj-Yahya

Patent number: 6802225Abstract: A differential-pressure flow sensor for airflow measurement in the presence of water condensation, for use with mechanical ventilators. The pressure-sensing ports at either end of the interfering body are displaced from the inner surface of the surrounding tubing, so as to prevent obstruction of the pressure-sensing ports by free flowing condensed water. The leading edge of the interfering body is angulated so as to deflect airflow towards the pressure-sensing port on the trailing edge of the interfering body, thereby flushing water droplets away from the port. The sides of the interfering body are sloped so as to generate turbulent boundary layer airflow at areas distant from the pressure-sensing ports, thereby encouraging water condensation away from the ports.Type: GrantFiled: July 24, 2002Date of Patent: October 12, 2004Assignee: Versamed Medical Systems Ltd.Inventors: Mark Shahar, Boaz Misholi, Sajed Haj-Yahya
