摘要： According to the present invention, a clear transmitted wave image of a boundary of tissues is generated in a short time. An ultrasonic imaging device of the present invention includes a transducer array in which a plurality of transducers transmitting and receiving an ultrasound wave are arrayed; a transmission unit which delivers an electric signal to at least one of the plurality of transducers, such that the delivered electric signal is converted into an ultrasound wave, and transmits the ultrasound wave to a target; a reception unit which receives a received signal that is an electric signal output by each of the plurality of transducers having received a reflected wave and a transmitted wave of the ultrasound wave of the target; and an image generation unit which individually generates a reflected wave image of a cross section of the target using a received signal of the reflected wave and a transmitted wave image of the cross section of the target using a received signal of the transmitted wave. The image generation unit includes a reflected wave image boundary detection unit detecting a boundary of the target in the reflected wave image and generating the transmitted wave image such that a boundary in the transmitted wave image corresponding to the boundary detected by the reflected wave image boundary detection unit is emphasized.

摘要： An imaging apparatus for diagnosis is disclosed, which has a motor drive unit (MDU) configured to be connected to a catheter, and which generates a vascular optical coherence tomographic image and an ultrasound tomographic image of a subject, based on a signal output from the catheter. The apparatus includes a first inspection unit that inspects the presence or absence of the ultrasound transceiver, based on intensity distribution of the electric signal of the reflected wave which is obtained by a first drive unit, and a second inspection unit that generates line image data in a radial direction, regarding a position of the imaging core as an origin, based on the electric signal of the interference light which is obtained by a second drive unit, and that inspects the presence or absence of the optical transceiver, based on pixel data distribution within a predetermined range from a position of the origin.

摘要： The speed of sound data corresponding to transmission of ultrasound through a cancerous lesion is different than the speed of sound data corresponding to transmission of ultrasound through a benign lesion. The system can assign a coloration to a speed of sound image according to the speed of sound through the tissue as obtained from quantitative transmission ultrasound. The shape indicative of a lesion can be identified through the reflection data with the type of lesion identifiable by the coloration from the speed of sound data.

摘要： A system and method for efficiently transmitting and receiving focused ultrasound through a medium, such as bone, is provided. The focal region of the focused ultrasound is iteratively updated to provide an improved focus through the medium. This method may be carried out using a transducer assembly that includes two or more transmit arrays each operating at a different frequency. An initial focus is set and updated by delivering focused ultrasound with a lower frequency transmit array. The phase corrections determined in the first iteration are applied to subsequently higher frequency transmit arrays and received signals, and the process repeated until a desired focus or image resolution is achieved.

摘要： A sensing assemblage (1) for capturing a transit time, phase, or frequency of energy waves propagating through a medium is disclosed to measure a parameter of the muscular-skeletal system. The sensing assemblage (1) comprises a transducer (2) and a waveguide (3). The transducer (2) is coupled to the waveguide (3) at a first location. A second transducer (11) can be coupled to the waveguide (3) at a second location. An interface material that is transmissive to acoustic energy waves can be placed between transducers (402, 404) and a waveguide (414) to improve transfer. The interface material (408, 410) can affix the transducers (402, 404) to the waveguide (414). Alternatively, a reflecting feature (5) can be placed at a second location of the waveguide (3) to reflect acoustic waves back to the transducer (2) where transducer (2) emits energy waves into the medium and detects propagated energy waves.
