To provide a composition for an
acoustic wave probe which can significantly improve the
hardness and the
mechanical strength (tensile strength at break, tensile elongation at break, tear strength, and abrasion resistance) of a
silicone resin while maintaining a low
acoustic attenuation, a
silicone resin for an
acoustic wave probe and the
acoustic wave probe using the composition for an acoustic wave probe, an acoustic wave measurement apparatus, and an
ultrasound diagnostic apparatus.To provide an
ultrasound probe in which cMUT is used as an ultrasonic diagnostic
transducer, and the composition for an acoustic wave probe and the
silicone resin for an acoustic wave probe which can improve the sensitivity of the photoacoustic wave measurement apparatus and the
ultrasound endoscope.Provided are a composition for an acoustic wave probe containing a polysiloxane mixture containing polysiloxane having a vinyl group, polysiloxane having two or more Si—H groups in a molecular chain, and one or more
inorganic compound particles, in which the average primary particle
diameter of the
inorganic compound particles is less than 25 nm and the
inorganic compound particles are selected from the group consisting of
magnesium oxide,
titanium oxide,
iron oxide,
zinc oxide,
zirconium oxide,
barium oxide,
tin oxide, and
ytterbium oxide; a
silicone resin for an acoustic wave probe; an acoustic wave probe; an acoustic wave measurement apparatus; an ultrasound diagnostic apparatus; an
ultrasound probe; a photoacoustic wave measurement apparatus; and an ultrasound
endoscope.
