Abstract: A method and ultrasound imaging system for detecting a coherent reflector includes acquiring ultrasound channel data from a volume with a probe, calculating a transform function from the ultrasound channel data, identifying a first angle of a projection of the coherent reflector in a plane parallel to the 2D aperture based on the transform function, detecting a line-shaped echo pattern in the ultrasound channel data, and determining a second angle of the coherent reflector with respect to the 2D aperture based on the position of the line-shaped echo pattern. The method and system includes determining a position and orientation of the coherent reflector based on the first angle and the second angle, enhancing a representation of the coherent reflector in an image generated based on the ultrasound channel data, and displaying the image on a display device after enhancing the representation of the coherent reflector.

Abstract: Various methods and systems are provided for ultrasound imaging with multi-line transmit. In one example, a method for ultrasound imaging comprises reducing an acoustic intensity at a position away from an array transducer of a combined beam formed from a plurality of transmit beams emitted by the array transducer in a multi-line transmit event by selectively adjusting one or more pulse parameters of one or more individual transmit beams of the combined beam for a given energy level of the one or more individual transmit beams.

Abstract: A system for measuring radiation dose comprises an excitation device adapted for directing an energy wave at a volume of a substance comprising gas-filled microparticles, a detector for detecting a response signal emitted and/or modified from the volume of the substance comprising gas-filled microparticles; and a control unit. The control unit is adapted for calculating a dose of ionizing radiation previously received by the volume of the substance based on the response signal. A method includes measuring a received dose of ionizing radiation and using a contrast agent for non-invasive in-situ dosimetry.
