Abstract
A simulated biological material for photoacoustic diagnostic apparatus contains a polyol or a cured material produced from a polyol and a polyisocyanate, and titanium oxide fine particles in the polyol or the cured material. The titanium oxide fine particles are surface-treated with a polysiloxane having a Si—H partial structure.
Claims10
A simulated biological material for photoacoustic diagnostic apparatuses, the material comprising:
- a polyol;
- and
- titanium oxide fine particles in the polyol, the titanium oxide fine particles being surface-treated with a polysiloxane having a Si—H partial structure.
A simulated biological material for photoacoustic diagnostic apparatuses, the material comprising:
- a urethane resin that is a cured material produced from a polyol and a polyisocyanate, and
- titanium oxide fine particles in the urethane resin, the titanium oxide fine particles being surface-treated with a polysiloxane having a Si—H partial structure.
A method for manufacturing a simulated biological material for photoacoustic diagnostic apparatuses, the method comprising:
- adding titanium oxide fine particles surface-treated with a polysiloxane having a Si—H partial structure to a polyol;
- and
- preparing a dispersion liquid by mixing and stirring the titanium oxide fine particles and the polyol so that the titanium oxide fine particles are uniformly dispersed in the polyol.
A method for manufacturing a simulated biological material for photoacoustic diagnostic apparatuses, the method comprising:
- adding titanium oxide fine particles surface-treated with a polysiloxane having a Si—H partial structure to a polyol;
- preparing a dispersion liquid by mixing and stirring the titanium oxide fine particles and the polyol so that the titanium oxide fine particles are uniformly dispersed in the polyol;
- preparing a curable composition containing the titanium oxide fine particles uniformly dispersed therein by adding a polyisocyanate to the dispersion liquid, and mixing and stirring the polyisocyanate and the dispersion liquid;
- and
- producing a urethane resin containing the titanium oxide fine particles uniformly dispersed therein by injecting the curable composition in a mold, and allowing the polyol to react with the polyisocyanate.
