The acoustic signal transmission couplants can conform to the receiving medium (e.g., skin) of the subject such that there is an acoustic impedance matching between the receiving medium and the transducer. In one aspect, an acoustic coupling medium includes a hydrogel including polymerizable material that form a network structured to entrap an aqueous fluid inside the hydrogel. The hydrogel is structured to conform to the receiving body, and the acoustic coupling medium is operable to conduct acoustic signals between acoustic signal transducer elements and a receiving medium when the hydrogel is in contact with the receiving body such that there is an acoustic impedance matching between the receiving medium and the acoustic signal transducer elements.



PROGRAM, METHOD AND DEVICE FOR ULTRASONIC DIAGNOSIS

Thu, 25 Aug 2016 08:00:00 EDT

An ultrasonic diagnosing device is provided, which accurately grasps a state of a detected part even in a case of analyzing the state of the detected part in a percutaneous manner. The ultrasonic diagnosing device includes a level assigning module configured to assign an echo intensity to one of a plurality of levels of echo intensities, the echo intensity being an intensity of each of echo signals respectively corresponding to positions in an area-of-interest, and a characteristic amount calculating module configured to calculate, by targeting two or more of samples having the echo intensities assigned to the plurality of levels by the level assigning module, characteristic amounts indicating a characteristic of the area-of-interest, based on a combination of the echo intensities of the two or more of the samples, the two or more of the samples having a given positional relationship with each other.
