Abstract: An endoscope system comprises an image acquisition unit, a discrimination processing unit, and a discrimination processing control unit. The image acquisition unit acquires an endoscope image obtained by imaging an observation target using an endoscope. The discrimination processing unit discriminates a portion having a specific feature in the observation target by performing discrimination processing, using an endoscope image. The discrimination processing control unit controls a start or an end of the discrimination processing on the basis of a change in operation of an endoscope or the endoscope image.

Abstract: Provided are a sound speed calculation system and a sound speed calculation method that can calculate a sound speed in a region of interest of a subject with high accuracy. A focus (F) of ultrasonic waves (w) is set in a portion that is farthest in the transmission direction of the ultrasonic waves (w) in a region of interest (35). Several second ultrasound transducers (51) to (69) receive ultrasound echoes from the focus (F). A sound speed in the region of interest (35) is calculated using ultrasound echo signals output from a first ultrasound transducer (60) that is closest to the focus (F), two second ultrasound transducers (51) and (69) that are other than the first ultrasound transducer, are located on straight lines (L2) passing through the focus (F) and the region of interest (35) of the subject, and have the first ultrasound transducer (60) interposed therebetween, and other ultrasound transducers (52) to (59) and (61) to (68) between the first ultrasound transducer (60) and the second ultrasound transducers (51) and (69).

Abstract: There are provided an ultrasound image generating apparatus, which generates a high-quality ultrasound image even in a deep portion of a subject, and a control method thereof. In an ultrasound image (Img), for a portion (Ar1) equal to or less than a depth threshold value (D1), a real scanning line (L1) obtained from an acoustic wave echo signal is used. In the ultrasound image (Img), for a portion (Ar2) deeper than the depth threshold value (D1), an interpolation scanning line (L2) located between the real scanning lines (L1) is generated from an acoustic wave echo signal having a positional deviation between a focusing position of ultrasound waves and an observation target position. Also for a portion deeper than the interpolation scanning line (L2), a high-quality ultrasound image (Img) is obtained.
