Provided are a resin material that provides a resin shaped article (such as a resin sheet) having an acoustic impedance close to that of a living body, a reduced acoustic wave attenuation even at high frequencies (such as 10 MHz), and high hardness and high tear strength, and that is suitable as a lens material for acoustic wave probes; an acoustic lens, an acoustic wave probe, an acoustic wave determination device, an ultrasound diagnostic apparatus, a photo-acoustic wave determination device, and an ultrasonic endoscope that employ the above-described resin material as a constituent material; and a method for producing the above-described acoustic lens.
An acoustic wave probe comprising an acoustic lens which comprises an acoustic-wave-probe resin material comprising a polymer that includes (a) a moiety having a polysiloxane bond, and (b) a moiety having at least one of an ester bond, an amide bond, a urethane bond, a urea bond, or an aromatic-ring-vinyl-derived structure, and that has a gel fraction of 60 mass % or more.
A photo-acoustic wave determination device comprising an acoustic lens which comprises an acoustic-wave-probe resin material comprising a polymer that includes (a) a moiety having a polysiloxane bond, and (b) a moiety having at least one of an ester bond, an amide bond, a urethane bond, a urea bond, or an aromatic-ring-vinyl-derived structure, and that has a gel fraction of 60 mass % or more.
An ultrasonic endoscope comprising an acoustic lens which comprises an acoustic-wave-probe resin material comprising a polymer that includes (a) a moiety having a polysiloxane bond, and (b) a moiety having at least one of an ester bond, an amide bond, a urethane bond, a urea bond, or an aromatic-ring-vinyl-derived structure, and that has a gel fraction of 60 mass % or more.
