Abstract
Since a medium having light propagation properties and sound propagation properties similar to those of human tissues is provided, reflection of light and an acoustic wave at a surface of a test portion is prevented, and accuracy control of a photoacoustic wave diagnostic apparatus is realized. A photoacoustic matching material is provided which includes a polyol, an inorganic oxide, and a pigment, the latter two being dispersable in the polyol, and in this photoacoustic matching material, a dispersed amount of the inorganic oxide to the polyol is in a range of 0.10 to 0.25 percent by weight, and a dispersed amount of the pigment to the polyol is in a range of 0.0001 to 0.0005 percent by weight.
Claims4
A phantom for a photoacoustic wave diagnostic apparatus, the phantom comprising:
- a base material;
- and
- an object to be detected,
- wherein the base material and the object to be detected contain polyol, an inorganic oxide and a pigment which are dispersable in the polyol, and an isocyanate compound,
- wherein a dispersed amount of the inorganic oxide to the polyol is in a range of 0.10 to 0.25 percent by weight,
- wherein a dispersed amount of the pigment to the polyol is in a range of 0.0001 to 0.0005 percent by weight, and
- wherein the dispersed amount of the pigment to the polyol in the base material is different from the dispersed amount of the pigment to the polyol in the object to be detected.
